Although various aspects of the embodiments are illustrated in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

It will be understood by those skilled in the art that the present application may be practiced without certain specific details. In some instances, methods, means, components and circuits that are well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.
首先，对本申请涉及的一些名词进行介绍。First, some terms involved in this application are introduced.
1、单栈模式：网络设备仅启用一个协议栈的模式。若网络设备的所有接口只配置了一种目标协议类型地址，则该网络设备为该目标协议的单栈模式。例如，目标协议为互联网协议第四版(Internet Protocol version 4，IPv4)，则网络设备为IPv4单栈模式。又例如，目标协议为互联网协议第六版(Internet Protocol version 6，IPv6)，则网络设备为IPv6单栈模式。1. Single stack mode: A mode in which the network device only enables one protocol stack. If all interfaces of a network device are configured with only one target protocol type address, the network device is in single-stack mode for that target protocol. For example, if the target protocol is Internet Protocol version 4 (IPv4), the network device is in IPv4 single-stack mode. For another example, if the target protocol is Internet Protocol version 6 (IPv6), the network device is in IPv6 single-stack mode.
2、双栈模式：网络设备同时启用两个协议栈的模式。若网络设备既存在配置了第一协议类型地址的接口，也存在配置了第二协议类型地址的接口，则该网络设备为双栈模式。例如，第一协议为IPv4，第二协议为IPv6。2. Dual stack mode: A mode in which the network device enables two protocol stacks at the same time. If the network device has both an interface configured with an address of the first protocol type and an interface configured with an address of the second protocol type, the network device is in dual-stack mode. For example, the first protocol is IPv4 and the second protocol is IPv6.
3、微分段(microsegmentation)：基于对报文进行分组后的组标识进行流量策略控制的技术。相关技术基于虚拟局域网(Virtual Local Area Network，VLAN)或虚拟网络接口(Virtual Network Interface，VNI)进行子网划分，再基于子网进行业务隔离，划分粒度较粗。微分段可以提供更细粒度、更灵活的分组方式，例如，微分段基于互联网协议(Internet Protocol，IP)地址、媒体存取控制(Media Access Control，MAC)地址、虚拟机名等对报文进行分组。因此，微分段可以进一步细化安全域的大小，实现更精细的业务隔离，提升网络安全性。3. Microsegmentation: A technology for traffic policy control based on group identifiers after grouping packets. Related technologies divide subnets based on virtual local area network (Virtual Local Area Network, VLAN) or virtual network interface (Virtual Network Interface, VNI), and then perform business isolation based on subnets, with a coarser granularity. Micro-segmentation can provide a more fine-grained and flexible grouping method. For example, micro-segmentation groups packets based on Internet Protocol (IP) addresses, Media Access Control (MAC) addresses, virtual machine names, etc. Group. Therefore, micro-segmentation can further refine the size of the security domain, achieve more refined business isolation, and improve network security.
4、SG表项：组播路由表中的(S，G)表项。每个(S，G)表项表示源S向组播组G发送组播数据的路由信息。例如，一个(S，G)表项包括源S(例如，一个单播IP地址)，组播组G(例如，一个组播IP地址)和接口标识，该接口标识指示的接口用于转发由源S发往组播组G的报文。4. SG entry: (S, G) entry in the multicast routing table. Each (S, G) entry represents routing information for source S to send multicast data to multicast group G. For example, a (S, G) entry includes source S (for example, a unicast IP address), multicast group G (for example, a multicast IP address), and an interface identifier indicating the interface used to forward the Packets sent by source S to multicast group G.
5、资源规格：一种资源在一个网络设备中的最大存储量。例如，资源为ARP表，网络设备A的ARP表的资源规格为1000条，表示该网络设备A中最多能存储1000条ARP表项。又例如，资源为MAC表，网络设备A的MAC表的资源规格为2000条，表示该网络设备A中最多能存储2000条MAC表项。资源规格又称为产品规格。5. Resource specifications: the maximum storage amount of a resource in a network device. For example, the resource is an ARP table, and the resource specification of the ARP table of network device A is 1000 entries, which means that network device A can store up to 1000 ARP entries. For another example, the resource is a MAC table, and the resource specification of the MAC table of network device A is 2000 entries, which means that network device A can store up to 2000 MAC table entries. Resource specifications are also called product specifications.
6、容量风险：网络设备中的一个或多个资源的使用量超过阈值。例如，若ARP表的资源规格为1000条，ARP表的风险阈值为80％，当网络设备中实际已存储的ARP表项的数量超过800条(即，ARP表的使用量超过800)时，表示该网络设备存在容量风险。也就是说，当网络设备的某一资源的存储量超过一定阈值时，后续可能会出现该资源存储失败的现象，导致与该资源相关的网络业务故障。 6. Capacity risk: The usage of one or more resources in the network device exceeds the threshold. For example, if the resource specification of the ARP table is 1000 entries and the risk threshold of the ARP table is 80%, when the actual number of ARP table entries stored in the network device exceeds 800 (that is, the usage of the ARP table exceeds 800), Indicates that the network device has capacity risk. That is to say, when the storage amount of a certain resource of a network device exceeds a certain threshold, subsequent storage failure of the resource may occur, resulting in network service failure related to the resource.
一种资源可能占用网络设备的多种存储资源。例如，一个ARP表项表示的是一个IP地址和一个MAC地址之间的对应关系，则存储一个ARP表项需要存储该IP地址、该MAC地址，和该IP地址和该MAC地址的对应关系。又例如，一个MAC表项表示的是一个MAC地址和一个接口的对应关系，则存储一个MAC表项需要存储该MAC地址、该接口的标识和该MAC地址和该接口的对应关系。网络设备通常将诸如IP地址、MAC地址等资源存储于网络设备的转发芯片的硬件存储资源中。网络设备通常将各表项包含的对应关系存储于网络设备的内存中，例如，将一个ARP表项关联的IP地址和MAC地址在转发芯片中的存储位置或索引存储于内存中。因此，一种资源的资源规格既与网络设备内转发芯片的资源分配规则相关，又与网络设备中的内存大小相关。One resource may occupy multiple storage resources of a network device. For example, an ARP entry represents the correspondence between an IP address and a MAC address. To store an ARP entry, you need to store the IP address, the MAC address, and the correspondence between the IP address and the MAC address. For another example, a MAC table entry represents the correspondence between a MAC address and an interface. To store a MAC table entry, you need to store the MAC address, the identifier of the interface, and the correspondence between the MAC address and the interface. Network devices usually store resources such as IP addresses and MAC addresses in hardware storage resources of the forwarding chip of the network device. Network devices usually store the corresponding relationships contained in each entry in the memory of the network device. For example, the storage location or index of the IP address and MAC address associated with an ARP entry in the forwarding chip is stored in the memory. Therefore, the resource specification of a resource is related to both the resource allocation rules of the forwarding chip in the network device and the memory size in the network device.
相关技术中，持续地向网络设备中配置同一种资源，直至配置失败，将配置失败时网络设备中已经存储的该资源的数量作为该资源的预设规格。针对于同一种网络设备，相关技术确定出的同种资源的预设规格相同。In the related art, the same resource is continuously configured in the network device until the configuration fails, and the quantity of the resource that has been stored in the network device when the configuration fails is used as the preset specification of the resource. For the same network device, the default specifications of the same resource determined by the relevant technology are the same.
然而，实际使用中，网络设备的存储空间(包括转发芯片的存储空间和内存的存储空间)可能会被多种资源占用，例如，ARP表，MAC表、FIB表等。因此，某一资源实际能占用的网络设备的存储空间会小于网络设备的最大存储空间。基于资源实际能占用的网络设备的存储空间确定的规格为资源的实际规格。因此，资源的预设规格通常与该资源的实际规格之间有较大的偏差，资源的预设规格通常会远大于资源的实际规格。网络设备基于预设规格计算出的资源利用率会偏小，可能导致网络设备的容量风险被漏报。However, in actual use, the storage space of the network device (including the storage space of the forwarding chip and the storage space of the memory) may be occupied by various resources, such as ARP table, MAC table, FIB table, etc. Therefore, the storage space of the network device that a certain resource can actually occupy will be less than the maximum storage space of the network device. The specifications determined based on the storage space of the network device that the resource can actually occupy are the actual specifications of the resource. Therefore, there is usually a large deviation between the default specifications of a resource and the actual specifications of the resource. The default specifications of a resource are usually much larger than the actual specifications of the resource. The resource utilization calculated by the network device based on the preset specifications will be too small, which may cause the capacity risk of the network device to be missed.
鉴于此，本申请实施例提供一种资源规格的确定方法和相关装置。本申请实施例基于网络设备的运行模式确定网络设备中资源的资源规格。网络设备的运行模式指示网络设备的至少一种功能的使能状态。使能不同功能的网络设备可能会存储不同种类的资源。本申请实施例基于网络设备的运行模式，考虑不同运行模式中每种运行模式对应的多种资源在网络设备内的共同存储情况，从而为多种资源中的每种资源分别确定资源规格，使得确定出的资源规格更接近资源在网络设备中的实际规格，进而使得基于该资源规格计算的资源利用率更准确，可以尽量避免网络设备漏报容量风险的问题。本申请实施例的详细方案请参考下述描述。In view of this, embodiments of the present application provide a method and related devices for determining resource specifications. The embodiment of the present application determines resource specifications of resources in the network device based on the operating mode of the network device. The operating mode of the network device indicates an enabling state of at least one function of the network device. Network devices that enable different functions may store different types of resources. Based on the operating mode of the network device, the embodiment of the present application considers the common storage situation of multiple resources corresponding to each operating mode in the different operating modes in the network device, thereby determining resource specifications for each of the multiple resources, so that The determined resource specifications are closer to the actual specifications of the resources in the network equipment, which in turn makes the resource utilization calculated based on the resource specifications more accurate and can minimize the risk of network equipment underreporting capacity. Please refer to the following description for detailed solutions of the embodiments of this application.
计算机设备执行资源规格的确定方法以确定目标网元的目标资源的资源规格。目标网元为网络中的一个网络设备，例如，交换机、路由器、防火墙或接入点(Access Point，AP)等。网络例如为数据中心网络(Data Center Network，DCN)、园区网络或者运营商网络等。可选地，计算机设备与目标网元是不同的设备。例如，目标网元为网络中的一个路由器，计算机设备为控制器、服务器、服务器集群、云设备、终端、网络中的网管设备，或网络中的其他网络设备。可选地，计算机设备与目标网元是相同的设备。例如，目标网元和计算机设备均为DCN中的一个路由器，该路由器根据自身的运行模式确定目标资源的资源规格。The computer device executes the resource specification determination method to determine the resource specifications of the target resources of the target network element. The target network element is a network device in the network, such as a switch, router, firewall or access point (AP), etc. The network is, for example, a Data Center Network (DCN), a campus network, or a carrier network. Optionally, the computer device and the target network element are different devices. For example, the target network element is a router in the network, and the computer device is a controller, server, server cluster, cloud device, terminal, network management device in the network, or other network equipment in the network. Optionally, the computer device and the target network element are the same device. For example, the target network element and computer equipment are both a router in the DCN, and the router determines the resource specifications of the target resources according to its own operating mode.
目标资源包括至少一种表项资源。表项资源例如为ARP表、ND协议表、IPv4路由表、IPv6路由表、组播路由表、虚拟路由转发(virtual routing and forwarding,VRF)实例表、逻辑接口表，访问控制列表(Access Control List,ACL)等。逻辑接口包括三层逻辑接口和/或二层逻辑接口。二层逻辑接口包括二层子接口。当目标资源仅包括一种表项资源时，计算机设备根据目标网元的运行模式确定该表项资源的资源规格。当目标资源包括多种表项 资源时，目标资源的资源规格包括该多种表项资源中的每种表项资源的资源规格，计算机设备根据目标网元的运行模式分别为每种表项资源确定资源规格。The target resource includes at least one entry resource. Table entry resources include, for example, ARP tables, ND protocol tables, IPv4 routing tables, IPv6 routing tables, multicast routing tables, virtual routing and forwarding (VRF) instance tables, logical interface tables, and access control lists. ,ACL) etc. Logical interfaces include Layer 3 logical interfaces and/or Layer 2 logical interfaces. Layer 2 logical interfaces include Layer 2 sub-interfaces. When the target resource only includes one entry resource, the computer device determines the resource specification of the entry resource based on the operating mode of the target network element. When the target resource includes multiple entries When resources are used, the resource specifications of the target resource include the resource specifications of each entry resource in the multiple entry resources. The computer device determines the resource specifications for each entry resource according to the operating mode of the target network element.
请参考图1，其示出了本申请实施例提供的一种资源规格的确定方法的流程示意图。该方法包括步骤101和102。Please refer to FIG. 1 , which shows a schematic flowchart of a method for determining resource specifications provided by an embodiment of the present application. The method includes steps 101 and 102.
步骤101，计算机设备获取目标网元的第一运行模式，第一运行模式指示目标网元的至少一种功能的使能状态。Step 101: The computer device acquires the first operating mode of the target network element, and the first operating mode indicates the enabling state of at least one function of the target network element.
第一运行模式指示目标网元的至少一种功能的使能状态。例如，第一运行模式为IPv4单栈模式，此时目标网元使能IPv4协议，不使能IPv6协议。又例如，第一运行模式为双栈模式，此时目标网元使能IPv4协议和IPv6协议。又例如，第一运行模式为IPv4单栈和组播模式，此时目标网元使能IPv4协议和组播功能。又例如，第一运行模式为IPv4单栈和微分段模式，此时目标网元使能IPv4协议和微分段功能。第一运行模式可以是多种运行模式中的一种，运行模式的种类由目标网元支持的功能决定。上述几种第一运行模式仅为举例，不构成对本申请实施例的限定。可以理解的是，目标网元支持的功能越多，功能间的组合也就越多，运行模式的种类会越多。The first operating mode indicates an enabling state of at least one function of the target network element. For example, the first operating mode is the IPv4 single-stack mode. At this time, the target network element enables the IPv4 protocol and disables the IPv6 protocol. For another example, the first operating mode is the dual-stack mode. At this time, the target network element enables the IPv4 protocol and the IPv6 protocol. For another example, the first operating mode is IPv4 single stack and multicast mode. At this time, the target network element enables the IPv4 protocol and multicast function. For another example, the first operating mode is IPv4 single stack and micro-segmentation mode. At this time, the target network element enables the IPv4 protocol and micro-segmentation function. The first operating mode may be one of multiple operating modes, and the type of operating mode is determined by the functions supported by the target network element. The above-mentioned first operating modes are only examples and do not constitute a limitation on the embodiments of the present application. It is understandable that the more functions the target network element supports, the more combinations between functions, and the more types of operating modes there will be.
可选地，计算机设备根据目标网元的运行场景确定目标网元的第一运行模式。不同的运行场景会要求网络设备支持不同的业务，进而导致网络设备使能不同的功能，处于不同的运行模式。例如，有的运行场景要求网络设备支持细粒度的业务隔离，此时网络设备可能需要使能微分段业务。又例如，有的运行场景要求网络设备支持IPv4业务和IPv6业务，此时网络设备需要使能双栈模式。可选地，计算机设备根据运行场景和运行模式的对应关系，将与目标网元的运行场景对应的运行模式确定为第一运行模式。例如，计算机设备维护一张运行场景和运行模式之间的映射表，该映射表的每个表项记录一种运行场景以及和该运行场景对应的运行模式。例如，每个表项存储运行场景的名称以及和该运行场景对应的运行模式的名称。计算机设备将目标网元的运行场景作为关键字，查询该映射表，以获取与该运行场景对应的第一运行模式。目标网元的运行场景可基于以下一项或多项确定：目标网元所属的网络、目标网元所处的位置，目标网元的角色，或目标网元的配置。目标网元的运行场景还可以是运维人员输入给计算机设备的。运行场景和运行模式的对应关系可以是预先配置的，例如，由运维人员配置，或者是其他的设备确定后又配置到该计算机设备。运行场景和运行模式的对应关系还可以是该计算机设备确定的，例如，该计算机设备获取网络中处于不同运行场景的网络设备使能的功能，基于每个网络设备使能的功能确定每个网络设备的运行模式，再基于每个网络设备的运行模式和该每个网络设备的运行场景确定运行场景和运行模式的对应关系。Optionally, the computer device determines the first operating mode of the target network element according to the operating scenario of the target network element. Different operating scenarios will require network equipment to support different services, which will lead to network equipment enabling different functions and operating in different operating modes. For example, some operating scenarios require network equipment to support fine-grained service isolation. In this case, the network equipment may need to enable micro-segmentation services. For another example, some operating scenarios require network equipment to support IPv4 services and IPv6 services. In this case, the network equipment needs to enable dual-stack mode. Optionally, the computer device determines the operating mode corresponding to the operating scenario of the target network element as the first operating mode according to the corresponding relationship between the operating scenario and the operating mode. For example, the computer device maintains a mapping table between operating scenarios and operating modes, and each entry in the mapping table records an operating scenario and an operating mode corresponding to the operating scenario. For example, each entry stores the name of the running scenario and the name of the running mode corresponding to the running scenario. The computer device uses the operating scenario of the target network element as a keyword to query the mapping table to obtain the first operating mode corresponding to the operating scenario. The operating scenario of the target network element can be determined based on one or more of the following: the network to which the target network element belongs, the location of the target network element, the role of the target network element, or the configuration of the target network element. The operation scenario of the target network element can also be input to the computer equipment by the operation and maintenance personnel. The corresponding relationship between the operating scenario and the operating mode can be pre-configured, for example, configured by operation and maintenance personnel, or other equipment is determined and then configured to the computer equipment. The corresponding relationship between operating scenarios and operating modes can also be determined by the computer device. For example, the computer device obtains the functions enabled by network devices in different operating scenarios in the network, and determines each network based on the functions enabled by each network device. The operating mode of the device, and then determine the corresponding relationship between the operating scenario and the operating mode based on the operating mode of each network device and the operating scenario of each network device.
可选地，计算机设备根据目标网元的至少一种功能的使能状态确定目标网元的第一运行模式。例如，目标网元使能IPv4协议，但未使能IPv6协议，则计算机设备可以将第一运行模式确定为IPv4单栈模式。又例如，目标网元使能IPv4协议和IPv6协议，又使能微分段功能，则计算机设备可以将第一运行模式确定为双栈和微分段模式。又例如，目标网元使能IPv4协议和IPv6协议，又使能组播功能，则计算机设备可以将第一运行模式确定为双栈和组播模式。图2所示的实施例详细地介绍了如何根据目标网元的至少一种功能的使能状态确定目标网元的运行模式，此处不再赘述。Optionally, the computer device determines the first operating mode of the target network element according to the enabling state of at least one function of the target network element. For example, if the target network element enables the IPv4 protocol but does not enable the IPv6 protocol, the computer device may determine the first operating mode as the IPv4 single-stack mode. For another example, if the target network element enables the IPv4 protocol and the IPv6 protocol, and also enables the micro-segmentation function, the computer device may determine the first operating mode as the dual-stack and micro-segmentation mode. For another example, if the target network element enables the IPv4 protocol and the IPv6 protocol, and also enables the multicast function, the computer device can determine the first operating mode as the dual stack and multicast mode. The embodiment shown in Figure 2 introduces in detail how to determine the operating mode of the target network element according to the enabling state of at least one function of the target network element, which will not be described again here.
步骤102，计算机设备根据第一运行模式确定目标网元的目标资源的资源规格，资源 规格指示目标资源在目标网元中的最大存储量。Step 102: The computer device determines the resource specification of the target resource of the target network element according to the first operating mode. The specification indicates the maximum storage amount of the target resource in the target network element.
计算机设备可以通过多种方式以根据第一运行模式确定目标网元的目标资源的资源规格。以下以方式一和方式二为例进行说明。The computer device may determine the resource specification of the target resource of the target network element according to the first operating mode through various methods. The following takes Method 1 and Method 2 as examples for explanation.
方式一，计算机设备根据第一运行模式，以及网络中运行模式为第一运行模式的多个网络设备的资源使用量和内存占用率确定目标网元的目标资源的资源规格。例如，计算机设备获取网络中运行模式为第一运行模式的多个网络设备的样本，每个样本包括一个网络设备的资源使用量和内存占用率。计算机设备对该多个样本进行聚类分析以获得资源使用量和内存占用率的典型区域(聚类簇)，再取聚类簇的类心附近的k个样本作为该典型区域的典型样本，之后再基于典型样本进行拟合分析(例如，神经网络拟合)。拟合的输入为内存占用率，输出为各资源的使用量。由此，计算机设备可获得内存占用率与各资源使用量之间的映射关系。根据该映射关系，计算机设备可获取当内存占用率为某个阈值(例如，80％)时，各资源使用量的一个近似值，根据各资源使用量的近似值确定该运行模式下的各资源的资源规格，例如，将各资源使用量的近似值作为该运行模式下各资源的资源规格。计算机设备可以获取网络中大量网络设备的资源使用量及内存占用率，再按运行模式对该多个网络设备进行分类，以获取多种运行模式的多个样本，再基于上述方法获取每种运行模式下各资源的资源规格。可以理解的是，上述多个网络设备和目标网元的设备类型相同，或者，上述多个网络设备的转发芯片的类型和目标网元的转发芯片的类型相同且上述多个网络设备的内存大小和目标网元的内存大小相同。可以理解的是，上述确定运行模式下的资源的资源规格的过程也可以由其他设备执行，例如，服务器执行上述过程以获取与目标网元同类型的网络设备在第一运行模式的目标资源的资源规格，并发送目标资源的资源规格给计算机设备。Method 1: The computer device determines the resource specifications of the target resources of the target network element based on the first operating mode and the resource usage and memory occupancy of multiple network devices in the network whose operating modes are the first operating mode. For example, the computer device obtains samples of multiple network devices in the network whose operating mode is the first operating mode, and each sample includes resource usage and memory usage of one network device. The computer equipment performs cluster analysis on the multiple samples to obtain typical areas (clustering clusters) of resource usage and memory usage, and then takes k samples near the center of the cluster as typical samples of the typical area. Then perform fitting analysis (for example, neural network fitting) based on typical samples. The input of the fitting is the memory usage, and the output is the usage of each resource. Thus, the computer device can obtain the mapping relationship between the memory usage and the usage of each resource. According to the mapping relationship, the computer device can obtain an approximate value of each resource usage when the memory occupancy rate is a certain threshold (for example, 80%), and determine the resources of each resource in the operating mode based on the approximate value of each resource usage. Specifications, for example, use the approximate value of each resource usage as the resource specification of each resource in this operating mode. The computer device can obtain the resource usage and memory usage of a large number of network devices in the network, and then classify the multiple network devices according to the operating mode to obtain multiple samples of multiple operating modes, and then obtain each operating mode based on the above method. Resource specifications of each resource in the mode. It can be understood that the device types of the multiple network devices and the target network element are the same, or the types of forwarding chips of the multiple network devices and the forwarding chips of the target network element are the same and the memory sizes of the multiple network devices are the same. The same as the memory size of the target network element. It can be understood that the above process of determining resource specifications of resources in the operating mode can also be performed by other devices. For example, the server performs the above process to obtain the target resource of the network device of the same type as the target network element in the first operating mode. resource specification, and sends the resource specification of the target resource to the computer device.
方式二，计算机设备根据运行模式和资源规格的对应关系以及第一运行模式，确定目标网元的目标资源的资源规格。可选地，该对应关系可以是预配置的。例如，服务器根据方式一获取与目标网元同类型的网络设备在多种运行模式下的各种资源的资源规格，并发送运行模式、设备类型和各资源的资源规格的对应关系给计算机设备，以配置运行模式和资源规格的对应关系。可选地，该对应关系可以是通过对运行模式关联的多种资源进行迭代存储测试确定的。该迭代测试过程可以包括如下步骤：Method 2: The computer device determines the resource specifications of the target resources of the target network element based on the corresponding relationship between the operating mode and the resource specification and the first operating mode. Optionally, the correspondence may be preconfigured. For example, the server obtains the resource specifications of various resources of network equipment of the same type as the target network element in multiple operating modes according to method 1, and sends the corresponding relationship between the operating mode, device type, and resource specifications of each resource to the computer device. To configure the corresponding relationship between the operating mode and resource specifications. Optionally, the corresponding relationship may be determined through iterative storage testing of multiple resources associated with the running mode. This iterative testing process can include the following steps:
步骤1，计算机设备根据第一运行模式指示的目标网元至少一种功能的使能状态确定该目标网元涉及的至少一种表项资源。例如，第一运行模式指示目标网元使能了IPv4和组播功能，则计算机设备确定该目标网元涉及IPv4路由表、组播路由表(例如，SG表)，以及其他相关的表项资源，例如，MAC表、ARP表。Step 1: The computer device determines at least one entry resource related to the target network element according to the enabling state of at least one function of the target network element indicated by the first operating mode. For example, the first operating mode indicates that the target network element has enabled IPv4 and multicast functions, then the computer device determines that the target network element involves an IPv4 routing table, a multicast routing table (for example, an SG table), and other related table entry resources. , for example, MAC table, ARP table.
步骤2，计算机设备为每个表项资源确定初始资源规格。初始资源规格可以是预设的。例如，ARP表：100，MAC表：300，IPv4路由表：1000，组播路由表：100。初始资源规格也可以是计算机设备通过方式一确定的。Step 2: The computer device determines the initial resource specification for each entry resource. Initial resource specifications can be preset. For example, ARP table: 100, MAC table: 300, IPv4 routing table: 1000, multicast routing table: 100. The initial resource specification may also be determined by the computer device through method one.
步骤3，计算机设备逐步在目标网元(或设备类型与目标网元相同的其他设备)上配置上述表项，直至满足第一条件或第二条件。针对一个表项资源，配置表项表示在目标网元上配置该资源的一个表项，例如，配置一个IPv4路由，配置一个组播路由，配置一个ARP表项，配置一个MAC表项。当接收到一个表项的配置指令时，目标网元存储该表项，例如，存储ARP表项中的IP地址、MAC地址，以及IP地址和MAC地址间的对应关系。 第一条件包括如下任一项：各个表项资源的实际配置量已达到初始资源规格(或调整后的初始资源规格)且目标网元的内存占用率小于等于(或小于)第一阈值、某一表项资源配置失败、表项资源配置失败的次数大于第二阈值、目标网元的内存占用率大于第三阈值。第二条件包括：各个表项资源的实际配置量已达到初始资源规格(或调整后的初始资源规格)且目标网元的内存占用率大于(或大于等于)第一阈值且小于(或小于等于)第三阈值。当满足第二条件时，计算机设备将各表项资源的初始资源规格(或调整后的初始资源规格)确定为第一运行模式对应的资源规格，不再执行后续步骤。当满足第一条件时，计算机设备继续执行后续步骤，以调整各表项资源的初始资源规格并再次进行测试。Step 3: The computer device gradually configures the above table entries on the target network element (or other devices of the same device type as the target network element) until the first condition or the second condition is met. For a table entry resource, configuring a table entry means configuring an entry for the resource on the target network element. For example, configuring an IPv4 route, configuring a multicast route, configuring an ARP entry, and configuring a MAC entry. When receiving a configuration instruction for an entry, the target network element stores the entry, for example, stores the IP address, MAC address in the ARP entry, and the correspondence between the IP address and the MAC address. The first condition includes any of the following: the actual configuration amount of each entry resource has reached the initial resource specification (or the adjusted initial resource specification) and the memory usage of the target network element is less than or equal to (or less than) the first threshold, a certain One table entry resource configuration fails, the number of table entry resource configuration failures is greater than the second threshold, and the memory usage of the target network element is greater than the third threshold. The second condition includes: the actual configuration amount of each entry resource has reached the initial resource specification (or the adjusted initial resource specification) and the memory usage of the target network element is greater than (or greater than or equal to) the first threshold and less than (or less than or equal to) ) third threshold. When the second condition is met, the computer device determines the initial resource specification (or the adjusted initial resource specification) of each entry resource as the resource specification corresponding to the first operating mode, and does not perform subsequent steps. When the first condition is met, the computer device continues to perform subsequent steps to adjust the initial resource specifications of each table item resource and perform testing again.
步骤4，当满足第一条件时，计算机设备调整各表项资源的初始资源规格。例如，若各个表项资源的实际配置量已达到初始资源规格且目标网元的内存占用率小于等于(或小于)第一阈值，则上调初始资源规格。又例如，若某一表项资源配置失败，或者表项资源配置失败的次数大于第二阈值，或者目标网元的内存占用率大于第三阈值，则下调初始资源规格。例如，按照一个比例(例如，5％)上调/下调表项资源的初始资源规格，或者，按照确切的数值(例如，5)上调/下调表项资源的初始资源规格。上调/下调表项资源的初始资源规格可以是上调/下调各表项资源的初始资源规格，也可以是上调/下调某一表项资源的初始资源规格，例如，仅下调存在配置失败的表项资源的初始资源规格。Step 4: When the first condition is met, the computer device adjusts the initial resource specifications of each entry resource. For example, if the actual configuration amount of each entry resource has reached the initial resource specification and the memory usage of the target network element is less than or equal to (or less than) the first threshold, the initial resource specification is increased. For another example, if a certain table entry resource configuration fails, or the number of table entry resource configuration failures is greater than the second threshold, or the memory usage of the target network element is greater than the third threshold, the initial resource specifications are lowered. For example, the initial resource specification of the entry resource is adjusted up/down according to a ratio (for example, 5%), or the initial resource specification of the entry resource is adjusted up/down according to an exact value (for example, 5). Up-adjusting/down-adjusting the initial resource specifications of table item resources can be to adjust up/down the initial resource specifications of each table item resource, or it can also be to adjust up/down the initial resource specifications of a certain table item resource. For example, only down-adjust table items with configuration failures. The resource's initial resource specification.
步骤5，基于调整后的初始资源规格，继续迭代执行步骤3，直至满足第二条件。Step 5: Based on the adjusted initial resource specifications, continue to iteratively execute Step 3 until the second condition is met.
可以理解的是，上述测试过程可以是预先进行的，例如，再部署目标网元之前对目标网元进行测试，或者再部署目标网元之后对目标网元同类型的网络设备进行测试。It can be understood that the above testing process can be performed in advance, for example, the target network element is tested before the target network element is deployed, or the same type of network equipment of the target network element is tested after the target network element is deployed.
可选地，目标网元的目标资源的资源规格用于计算目标资源的资源利用率。Optionally, the resource specification of the target resource of the target network element is used to calculate the resource utilization of the target resource.
可选地，目标资源的资源利用率用于评估目标网元是否存在容量风险。Optionally, the resource utilization of the target resource is used to evaluate whether the target network element has capacity risks.
综上所述，本申请实施例基于目标网元的运行模式确定目标网元中资源的资源规格。目标网元的运行模式指示目标网元的至少一种功能的使能状态。使能不同功能的网络设备可能会存储不同种类的资源。本申请实施例基于目标网元的运行模式，考虑不同运行模式中每种运行模式对应的多种资源在目标网元内的共同存储情况，从而为多种资源中的每种资源分别确定资源规格，使得确定出的资源规格更接近资源在目标网元中的实际规格，进而使得基于该资源规格计算的资源利用率更准确，可以尽量避免漏报网络设备的容量风险的问题。To sum up, the embodiment of the present application determines the resource specifications of the resources in the target network element based on the operating mode of the target network element.

Network devices that enable different functions may store different types of resources. Based on the operating mode of the target network element, the embodiment of the present application considers the common storage situation of multiple resources corresponding to each operating mode in the different operating modes in the target network element, thereby determining resource specifications for each of the multiple resources. , making the determined resource specifications closer to the actual specifications of the resources in the target network element, thereby making the resource utilization calculated based on the resource specifications more accurate, and minimizing the problem of underreporting the capacity risk of network equipment.

步骤201，计算机设备获取目标网元的运行特征。Step 201: The computer device obtains the operating characteristics of the target network element.
可选地，计算机设备根据目标网元的至少一种功能的使能状态获取目标网元的运行特征。可选地，计算机设备获取目标网元的配置信息，根据目标网元的配置信息确定目标网元的至少一种功能的使能状态，从而获取目标网元的运行特征。例如，计算机设备获取目标网元的配置文件以获取配置信息。配置文件例如为目标网元的接口配置文件、功能配置文件等。接口配置文件包括每个接口配置的地址类型，例如，IPv4地址和/或IPv6地址。功能配置文件包括目标网元的功能的使能状态，例如，目标网元是否使能了组播功能、微分段功能，虚拟专用网(virtual private network,VPN)功能等。 Optionally, the computer device acquires the operating characteristics of the target network element according to the enabling state of at least one function of the target network element. Optionally, the computer device obtains the configuration information of the target network element, and determines the enabling state of at least one function of the target network element based on the configuration information of the target network element, thereby obtaining the operating characteristics of the target network element. For example, the computer device obtains the configuration file of the target network element to obtain the configuration information. The configuration file is, for example, the interface configuration file, function configuration file, etc. of the target network element. The interface configuration file includes the address type configured for each interface, for example, IPv4 address and/or IPv6 address. The function configuration file includes the enabling status of the target network element's functions, for example, whether the target network element has the multicast function, micro-segmentation function, virtual private network (VPN) function, etc. enabled.
可选地，运行特征包括以下至少一项运行子特征：目标网元使能的协议栈类型，目标网元的业务功能的使能状态。业务功能例如为组播功能、微分段功能，VPN功能等。Optionally, the operating characteristics include at least one of the following operating sub-characteristics: the protocol stack type enabled by the target network element, and the enabling status of the service function of the target network element. Business functions include multicast function, micro-segmentation function, VPN function, etc.
计算机设备根据接口配置文件确定目标网元使能的协议栈类型。例如，当接口配置文件中仅存在配置了第一协议类型地址的接口时，确定目标网元使能的协议栈类型为第一协议；当接口配置文件中仅存在配置了第二协议类型地址的接口时，确定目标网元使能的协议栈类型为第二协议；当接口配置文件中既存在配置了第一协议类型地址的接口，也存在配置了第二协议类型地址的接口时，确定目标网元使能的协议栈类型为第一协议和第二协议，即，双栈模式。例如，第一协议为IPv4，第二协议为IPv6。The computer device determines the protocol stack type enabled by the target network element according to the interface configuration file. For example, when there are only interfaces configured with addresses of the first protocol type in the interface configuration file, determine that the protocol stack type enabled on the target network element is the first protocol; when there are only interfaces configured with addresses of the second protocol type in the interface configuration file. interface, determine that the protocol stack type enabled on the target network element is the second protocol; when there are both interfaces configured with the first protocol type address and interfaces configured with the second protocol type address in the interface configuration file, determine the target The protocol stack types enabled by the network element are the first protocol and the second protocol, that is, dual stack mode. For example, the first protocol is IPv4 and the second protocol is IPv6.
计算机设备根据功能配置文件确定目标网元的业务功能的使能状态。功能配置文件可以为一个配置文件。例如，一个配置文件中列出了目标网元使能的所有业务功能，例如，该配置文件包括目标网元使能的业务功能的名称。计算机设备将该配置文件中的所有业务功能的使能状态确定为使能(是)，将不在该配置文件中的其他业务功能的使能状态确定为未使能(否)。又例如，该配置文件列出了目标网元支持的所有业务功能，并明确的标识了目标网元使能的业务功能和没有使能的业务功能，例如，该配置文件列出了目标网元支持的所有的业务功能的名称，以及与每个业务功能的名称对应的取值，取值为第一值指示目标网元使能了与该取值对应的业务功能，取值为第二值指示目标网元未使能与该取值对应的业务功能。第一值例如为1，第二值例如为0。计算机设备将该配置文件中的取值为第一值的业务功能的使能状态确定为使能(是)，将该配置文件中的取值为第二值的业务功能的使能状态确定为未使能(否)。功能配置文件也可以包括多个配置文件，每个配置文件与目标网元使能的一个业务功能对应。The computer device determines the enabling status of the service function of the target network element according to the function configuration file. The function configuration file can be a configuration file. For example, a configuration file lists all the service functions enabled by the target network element. For example, the configuration file includes the names of the service functions enabled by the target network element. The computer device determines the enabling status of all business functions in the configuration file as enabled (yes), and determines the enabling status of other business functions not in the configuration file as not enabled (no). For another example, the configuration file lists all the service functions supported by the target network element, and clearly identifies the service functions enabled and unenabled by the target network element. For example, the configuration file lists the service functions supported by the target network element. The names of all supported business functions, and the value corresponding to the name of each business function. The first value indicates that the target network element has enabled the service function corresponding to the value. The second value Indicates that the service function corresponding to this value is not enabled on the target network element. The first value is, for example, 1, and the second value is, for example, 0. The computer device determines the enabling state of the business function whose value is the first value in the configuration file as enabled (yes), and determines the enabling state of the business function whose value is the second value in the configuration file as Not enabled (No). The function configuration file may also include multiple configuration files, and each configuration file corresponds to a service function enabled by the target network element.
以业务功能包括组播功能和微分段功能为例，在一个示意性的例子中，目标网元的所有接口均仅配置了IPv4地址，且该目标网元未使能组播功能和微分段功能，则提取的运行特征即目标网元使能的协议栈类型、目标网元的组播功能的使能情况、目标网元的微分段功能的使能情况，分别为：IPv4单栈、否、否。Taking the service functions including multicast function and micro-segmentation function as an example, in an illustrative example, all interfaces of the target network element are configured with only IPv4 addresses, and the multicast function and micro-segmentation function are not enabled on the target network element. , then the extracted operating characteristics are the protocol stack type enabled by the target network element, the enabling status of the multicast function of the target network element, and the enabling status of the micro-segmentation function of the target network element, respectively: IPv4 single stack, No, no.

The first mapping table indicates the corresponding relationship between the operating characteristics and the operating mode. The first mapping table includes a plurality of first entries, and each first entry indicates the corresponding relationship between the operating characteristics and the operating mode.

可选地，运行模式的总数量与目标网元支持的功能的数量相关，计算机设备可以根据目标网元支持的功能的组合确定目标网元可以执行的多种运行模式，以获取第一映射表。例如，若目标网元支持IPv4协议、IPv6协议、组播业务和微分段业务，则运行模式可以包括：IPv4单栈模式、IPv6单栈模式、IPv4单栈和组播模式、IPv4单栈和微分段模式、IPv6单栈和组播模式、IPv6单栈和微分段模式、双栈模式、双栈和组播模式、双栈和微分段模 式、IPv4单栈和组播微分段模式、IPv6和组播微分段模式，双栈和组播微分段模式。Optionally, the total number of operating modes is related to the number of functions supported by the target network element. The computer device can determine multiple operating modes that the target network element can execute according to the combination of functions supported by the target network element to obtain the first mapping table. . For example, if the target network element supports IPv4 protocol, IPv6 protocol, multicast service and micro-segmentation service, the operating modes may include: IPv4 single stack mode, IPv6 single stack mode, IPv4 single stack and multicast mode, IPv4 single stack and differential Segment mode, IPv6 single stack and multicast mode, IPv6 single stack and micro-segmentation mode, dual stack mode, dual stack and multicast mode, dual stack and micro-segmentation mode mode, IPv4 single stack and multicast micro-segmentation mode, IPv6 and multicast micro-segmentation mode, dual stack and multicast micro-segmentation mode.

表1
Table 1
可选地，第一映射表中的运行特征还可以包括网络设备的第一资源的资源规格和网络设备的第二资源的资源规格的比例。例如，第一资源为IPv4路由表(即，FIBv4表)，第二资源为IPv6路由表(即，FIBv6表)，则运行特征还可以包括FIBv4表的资源规格与IPv6路由表的资源规格的比例。又例如，第一资源为VRF实例表，第二资源为二层子接口表，则运行特征还可以包括VRF实例表的资源规格与二层子接口表的资源规格的比例。Optionally, the operating characteristics in the first mapping table may also include a ratio of resource specifications of the first resource of the network device and resource specifications of the second resource of the network device. For example, if the first resource is an IPv4 routing table (i.e., FIBv4 table), and the second resource is an IPv6 routing table (i.e., FIBv6 table), the operating characteristics may also include the ratio of the resource specifications of the FIBv4 table to the resource specifications of the IPv6 routing table. . For another example, if the first resource is a VRF instance table and the second resource is a Layer 2 sub-interface table, the operation characteristics may also include the ratio of the resource specifications of the VRF instance table to the resource specifications of the Layer 2 sub-interface table.
当目标网元中不存在第一资源或第二资源时，该比例为空(或，NULL)。例如，当目标网元既使能IPv4又使能IPv6时，计算机设备还可以获取目标网元中的已配置的IPv4的路由表项的数量和目标网元中的已配置的IPv6的路由表项的数量，并将二者的比值作为目标网元中第一资源的使用量与第二资源的使用量的比例。When the first resource or the second resource does not exist in the target network element, the ratio is empty (or NULL). For example, when the target network element enables both IPv4 and IPv6, the computer device can also obtain the number of configured IPv4 routing table entries in the target network element and the configured IPv6 routing table entries in the target network element. quantity, and the ratio between the two is regarded as the ratio of the usage of the first resource to the usage of the second resource in the target network element.
示例性地，表2示出了另一种第一映射表的示意图。根据FIBv4表的使用量与IPv6路由表的使用量的比例将双栈模式细分为双栈模式1和双栈模式2。可以理解的是，表2没有穷举所有运行模式，而是仅以几个运行模式的例子示意性的说明第一映射表。By way of example, Table 2 shows a schematic diagram of another first mapping table. The dual-stack mode is subdivided into dual-stack mode 1 and dual-stack mode 2 based on the ratio of the usage of the FIBv4 table to the usage of the IPv6 routing table. It can be understood that Table 2 does not exhaust all operating modes, but only schematically illustrates the first mapping table with examples of several operating modes.

Table 2
示例性地，表3示出了另一种第一映射表的示意图。该表中，根据VRF实例表的使用量和二层子接口表的使用量将IPv4单栈模式细分为IPv4单栈模式1和IPv4单栈模式2。可以理解的是，表1没有穷举所有运行模式，而是仅以几个运行模式的例子示意性的说明第一映射表。Exemplarily, Table 3 shows a schematic diagram of another first mapping table. In this table, the IPv4 single-stack mode is subdivided into IPv4 single-stack mode 1 and IPv4 single-stack mode 2 based on the usage of the VRF instance table and the usage of the Layer 2 sub-interface table. It can be understood that Table 1 does not exhaust all operating modes, but only schematically illustrates the first mapping table with examples of several operating modes.

可选地，目标网元的运行特征包括多个运行子特征，计算机设备根据第一映射表，确定匹配的第一表项，并将该匹配的第一表项中的运行模式确定为第一运行模式，匹配的第一表项包括的多个子特征与多个运行子特征均匹配。示意性的，计算机设备以多个运行子特征作为关键字，在第一映射表中查询各个第一表项，若查询到与某个第一表项包括的多个子特征与多个运行子特征均匹配，则将该第一表项包括的运行模式确定为第一运行模式。Optionally, the operating characteristics of the target network element include multiple operating sub-characteristics. The computer device determines the matching first entry according to the first mapping table, and determines the operating mode in the matching first entry as the first In the running mode, the multiple sub-features included in the matched first entry all match the multiple running sub-features. Illustratively, the computer device uses multiple operating sub-features as keywords to query each first entry in the first mapping table. If multiple sub-features and multiple operating sub-features included in a certain first entry are queried, If all match, the operating mode included in the first entry is determined as the first operating mode.
可选地，当不存在匹配的第一表项时，计算机设备确定多个第一表项分别对应的匹配分数，并根据多个第一表项分别对应的匹配分数，确定第一运行模式。其中，任一第一表项的匹配分数指示多个运行子特征与该任一第一表项包括的多个子特征之间的匹配程度。Optionally, when there is no matching first entry, the computer device determines the matching scores corresponding to the plurality of first entries, and determines the first operating mode based on the matching scores corresponding to the plurality of first entries. The matching score of any first entry indicates the matching degree between the plurality of operating sub-features and the plurality of sub-features included in the any first entry.
示意性的，每个第一表项对应的匹配分数为该第一表项包括的多个子特征的匹配分数的加权值。例如，计算机设备可以为“使能的协议类型”这一子特征设置更高的权重(例如，0.8)，而为其他子特征设置更低的权重(例如，0.2)，当运行模式的一个子特征和目标网元中的对应的第一子特征匹配时，设置该子特征的匹配分数为1，否则设置该子特征的匹配分数为0，计算机设备基于每个子特征的匹配分数和权重求和以获取该第一表项的匹配分数。Illustratively, the matching score corresponding to each first entry is a weighted value of the matching scores of multiple sub-features included in the first entry. For example, a computer device may set a higher weight (e.g., 0.8) for the sub-characteristic "enabled protocol type" and lower weights (e.g., 0.2) for other sub-characteristics. When a sub-characteristic of the operating mode When the feature matches the corresponding first sub-feature in the target network element, the matching score of the sub-feature is set to 1, otherwise the matching score of the sub-feature is set to 0, and the computer device calculates the sum based on the matching score and weight of each sub-feature. To obtain the matching score of the first table entry.
子特征和运行子特征匹配可以是子特征的取值与运行子特征的取值完全相同。可选地，当运行子特征为数值特征(例如，IPv4协议路由数与IPv6协议路由数的比例)时，子特征和第一子特征匹配也可以是子特征的值与运行子特征的值差值小于阈值，或者是运行子特征的近似值与子特征的值完全相同。运行子特征的近似值例如为运行子特征的数值修约值。数值修约例如为四舍五入、五舍六入、向上取整、向下取整等。The matching of sub-features and running sub-features can be that the value of the sub-feature is exactly the same as the value of the running sub-feature. Optionally, when the running sub-feature is a numerical feature (for example, the ratio of the number of IPv4 protocol routes to the number of IPv6 protocol routes), the match between the sub-feature and the first sub-feature can also be the difference between the value of the sub-feature and the value of the running sub-feature. The value is less than the threshold, or the approximate value of the running subfeature is exactly the same as the value of the subfeature. The approximate value of the operating sub-characteristic is, for example, the numerical rounding value of the operating sub-characteristic. Numerical rounding includes, for example, rounding, rounding up, rounding down, etc.
可选地，计算机设备根据多个第一表项分别对应的匹配分数，确定第一运行模式，包括：当匹配分数最高的第一表项仅为一个第一表项时，将该第一表项包括的运行模式确定为第一运行模式；当匹配分数最高的第一表项包括多个第一表项时，将该多个第一表项包括的运行模式作为候选模式，根据第一策略确定目标资源使用量与每个候选运行模式之间的匹配程度，将匹配程度最高的候选运行模式确定为第一运行模式。例如，第一策略可以 为宽松策略，此时，当目标资源使用量与候选运行模式对应的资源规格越远离(或，接近程度低)时，则该候选运行模式的匹配程度越高。又例如，第一策略可以为严厉策略，此时，当目标资源使用量与候选运行模式对应的资源规格越接近(或，接近程度高)时，则该候选运行模式的匹配程度越高。可选地，目标资源使用量可以是计算机设备最近一次获取到的目标网元的目标资源使用量，也可以是是基于历史的目标资源的使用量预测得到的目标资源使用量。历史的目标资源使用量为第一时间段内目标网元中的目标资源的实际使用量。第一时间段早于确定第一运行模式的时间。Optionally, the computer device determines the first operating mode based on the matching scores respectively corresponding to the multiple first entries, including: when the first entry with the highest matching score is only one first entry, converting the first entry to The operating mode included in the entry is determined as the first operating mode; when the first entry with the highest matching score includes multiple first entries, the operating mode included in the multiple first entries is used as a candidate mode, and according to the first strategy The matching degree between the target resource usage and each candidate operating mode is determined, and the candidate operating mode with the highest matching degree is determined as the first operating mode. For example, the first strategy can It is a loose strategy. At this time, when the target resource usage is further away from (or closer to) the resource specification corresponding to the candidate operating mode, the higher the matching degree of the candidate operating mode. For another example, the first policy may be a strict policy. In this case, when the target resource usage is closer to the resource specification corresponding to the candidate operating mode (or the degree of closeness is higher), the higher the matching degree of the candidate operating mode. Optionally, the target resource usage may be the target resource usage of the target network element most recently obtained by the computer device, or may be the target resource usage predicted based on historical target resource usage. The historical target resource usage is the actual usage of the target resource in the target network element in the first time period. The first time period is earlier than the time at which the first operating mode is determined.
可选地，计算机设备根据目标资源的使用量和候选运行模式中的目标资源的资源规格之间的距离，确定目标资源使用量与候选运行模式中的目标资源的资源规格的接近程度。距离计算公式例如为d＝min1→k((yk-xk)/yk)，其中，k表示目标资源包括的表项资源的个数，yk表示一个候选运行模式中的第k个表项资源的资源规格，xk表示目标资源中的第k个表项资源的资源使用量，d表示目标资源的使用量与该候选运行模式中的目标资源的资源规格之间的距离。计算机设备可以分别计算每个候选运行模式中的资源规格与目标资源的资源使用量之间的距离，距离越大指示接近程度越低，距离越小指示接近程度越高。Optionally, the computer device determines how close the target resource usage is to the resource specification of the target resource in the candidate operating mode based on the distance between the target resource usage and the resource specification of the target resource in the candidate operating mode. The distance calculation formula is, for example, d=min 1→k ((y k -x k )/y k ), where k represents the number of entry resources included in the target resource, and y k represents the k-th entry resource in a candidate operating mode. The resource specification of the entry resource, x k represents the resource usage of the k-th entry resource in the target resource, and d represents the distance between the usage of the target resource and the resource specification of the target resource in the candidate operating mode. The computer device may separately calculate the distance between the resource specifications in each candidate operating mode and the resource usage of the target resource, with a larger distance indicating a lower degree of proximity, and a smaller distance indicating a higher degree of proximity.
例如，若目标网元的目标资源的资源使用量如表4所示，2个候选模式的资源规格如表5所示，则基于上述距离计算公式可以计算出两个候选运行模式的距离值分别为-1.25,0.1，若策略为宽松策略，则确定目标网元的第一运行模式为距离值较大的IPv4单栈模式2，若策略为严厉策略，则确定目标网元的第一运行模式为距离值较小的IPv4单栈模式1。For example, if the resource usage of the target network element's target resources is as shown in Table 4, and the resource specifications of the two candidate modes are as shown in Table 5, then the distance values of the two candidate operating modes can be calculated based on the above distance calculation formula. is -1.25,0.1. If the policy is a loose policy, determine the first operating mode of the target network element to be IPv4 single-stack mode 2 with a larger distance value. If the policy is a strict policy, determine the first operating mode of the target network element. It is IPv4 single stack mode 1 with a small distance value.

Table 6 exemplarily shows five operating modes and resource specifications corresponding to different types of network elements in each operating mode. The first type of network elements is different from the second type of network elements. The equipment models of the first type network element and the second type network element are different. For example, the equipment model of the first type network element is M1, and the equipment model of the second type network element is M2.

For example, the equipment models of the first type network element and the second type network element are both M3, but the version identifier of the first type network element is v1.

综上所述，本申请实施例中，计算机设备基于目标网元的配置信息，提取目标网元的运行特征，再基于目标网元的运行特征确定目标网元的运行模式，这使得确定出的运行模式更匹配目标网元的实际配置。之后，计算机设备再基于目标网元的运行模式确定目标资源的资源规格，使得确定出的资源规格更接近目标资源在目标网元中的实际规格，进而使得基于该资源规格计算的资源利用率更准确，可以尽量避免网络设备漏报容量风险的问题。To sum up, in the embodiments of the present application, the computer device extracts the operating characteristics of the target network element based on the configuration information of the target network element, and then determines the operating mode of the target network element based on the operating characteristics of the target network element, which makes the determined The running mode better matches the actual configuration of the target network element. After that, the computer device determines the resource specifications of the target resources based on the operating mode of the target network element, so that the determined resource specifications are closer to the actual specifications of the target resources in the target network element, thereby making the resource utilization calculated based on the resource specifications more accurate. Accurate, you can try to avoid the problem of network equipment underreporting capacity risks.
在基于图1或图2所示的实施例确定出目标网元中的目标资源的资源规格后，计算机设备还可以基于目标资源的资源规格评估目标网元的容量风险。请参看图3，其示出了本申请实施例提供的一种容量风险的评估方法的流程示意图。该方法包括步骤301至步骤302。After determining the resource specifications of the target resources in the target network element based on the embodiment shown in FIG. 1 or FIG. 2 , the computer device can also evaluate the capacity risk of the target network element based on the resource specifications of the target resources. Please refer to FIG. 3 , which shows a schematic flow chart of a capacity risk assessment method provided by an embodiment of the present application. The method includes steps 301 to 302.
步骤301，计算机设备根据目标资源的资源使用量和资源规格，确定目标资源的资源利用率。Step 301: The computer device determines the resource utilization rate of the target resource based on the resource usage and resource specifications of the target resource.
资源规格的获取方式请参考图1或图2所示的实施例，此处不再赘述。For the method of obtaining resource specifications, please refer to the embodiment shown in Figure 1 or Figure 2, which will not be described again here.
计算机设备获取目标资源在目标网元中的资源使用量。当计算机设备和目标网元为同一个设备时，目标网元读取目标资源的使用量。当计算机设备和目标网元为两个不同的设备时，计算机设备可以发送消息给目标网元以促使目标网元读取目标资源的使用量并返回目标资源的使用量给计算机设备，或者，目标网元还可以周期性地主动发送目标资源的使用量给计算机设备，计算机设备将最近一次接收到的来自于目标网元的目标资源的使用量用于自己算目标资源利用率。The computer device obtains the resource usage of the target resource in the target network element. When the computer device and the target network element are the same device, the target network element reads the usage of the target resource. When the computer device and the target network element are two different devices, the computer device can send a message to the target network element to prompt the target network element to read the usage of the target resource and return the usage of the target resource to the computer device, or the target The network element can also periodically actively send the usage of the target resource to the computer device, and the computer device uses the latest usage of the target resource received from the target network element to calculate the target resource utilization.
可选地，计算机设备还可以基于历史的目标资源的使用量预测得到的目标资源的资源使用量。历史的目标资源使用量为第一时间段内目标网元中的目标资源的实际使用量。第一时间段早于确定第一运行模式的时间。例如，目标资源的资源使用量为第一时间段内的目标资源的多个使用量的加权均值。第一时间段内的目标资源的每个资源使用量的权重可以相同，也可以不同，例如，时间上越接近于当前时刻的资源利用率的权重越大。例如，一种可能的加权平均公式为Xi为第一时间段内的目标资源的第i个资源使用量，n为第一时间段内的目标资源的资源利用率的数量，i/(n(n+1)/2)为第i个资源使用量的权重。若n＝5，表7示出基于第一时间段内的5个资源利用率确定的当前的(即，第6个)资源利用率。Optionally, the computer device may also predict the resource usage of the target resource based on the historical usage of the target resource. The historical target resource usage is the actual usage of the target resource in the target network element in the first time period. The first time period is earlier than the time at which the first operating mode is determined. For example, the resource usage of the target resource is a weighted average of multiple usages of the target resource in the first time period. The weight of each resource usage of the target resource in the first time period may be the same or different. For example, the resource utilization closer to the current moment in time has a greater weight. For example, one possible weighted average formula is X i is the i-th resource usage of the target resource in the first time period, n is the number of resource utilization of the target resource in the first time period, i/(n(n+1)/2) is the The weight of i resource usage. If n=5, Table 7 shows the current (ie, 6th) resource utilization determined based on the 5 resource utilizations within the first time period.

需要说明的是，目标资源使用量的获取过程与目标资源规格的确定过程可以分先后顺序执行，也可以并列执行，本申请实施例对此不加以限定。It should be noted that the process of obtaining the target resource usage and the process of determining the target resource specifications can be executed sequentially or in parallel, which is not limited in the embodiments of the present application.
可选地，计算机设备根据目标资源的资源使用量和资源规格，确定目标资源的资源利用率，包括：将目标资源的资源使用量与目标资源的资源规格的比值确定为目标资源的资源利用率。 Optionally, the computer device determines the resource utilization of the target resource based on the resource usage and resource specifications of the target resource, including: determining a ratio of the resource usage of the target resource to the resource specifications of the target resource as the resource utilization of the target resource. .
可选地，目标资源包括多个第一资源，目标资源的资源使用量包括多个第一资源中的每个第一资源的资源使用量，目标资源的资源利用率包括多个第一资源中的每个第一资源的资源利用率，每个第一资源的资源利用率为该第一资源的资源使用量与该第一资源的资源规格的比值。例如，如表8所示，目标资源可以包括以下多个第一资源：VRF实例表、三层逻辑接口表、二层子接口表、ARP表、FIBv4表。如表8所示，当VRF实例表的资源使用量(即，目标网元中已经配置的VRF实例的个数)为50，VRF实例表的资源规格为100时，VRF实例表的资源利用率为50％；当三层逻辑接口表资源使用量(即，目标网元中已经配置的三层逻辑接口的个数)为800，三层逻辑接口表的资源规格为1500时，三层逻辑接口表的资源利用率为53.3％；当二层子接口表的资源使用量(即，目标网元中已经配置的二层子接口的个数)为4500，二层子接口表的资源规格为5000时，二层子接口表的资源利用率为90％；当ARP表的资源使用量(即，目标网元中已经配置的ARP表项的个数)为2000，ARP表的资源规格为2500时，ARP表的资源利用率为80％；当FIBv4表的资源使用量(即，目标网元中已经配置的IPv4路由的数量)为1500，FIBv4表的资源规格为2500时，FIBv4表的的资源利用率为60％。Optionally, the target resource includes multiple first resources, the resource usage of the target resource includes the resource usage of each of the multiple first resources, and the resource utilization rate of the target resource includes the resource usage of the multiple first resources. The resource utilization rate of each first resource is the ratio of the resource usage of the first resource to the resource specification of the first resource. For example, as shown in Table 8, the target resources may include the following multiple first resources: VRF instance table, Layer 3 logical interface table, Layer 2 sub-interface table, ARP table, and FIBv4 table. As shown in Table 8, when the resource usage of the VRF instance table (that is, the number of VRF instances configured in the target network element) is 50 and the resource specification of the VRF instance table is 100, the resource utilization of the VRF instance table is 50%; when the resource usage of the Layer 3 logical interface table (that is, the number of Layer 3 logical interfaces configured in the target network element) is 800, and the resource specification of the Layer 3 logical interface table is 1500, the Layer 3 logical interface The resource utilization rate of the table is 53.3%; when the resource usage of the Layer 2 sub-interface table (that is, the number of Layer 2 sub-interfaces configured in the target network element) is 4500, the resource specification of the Layer 2 sub-interface table is 5000 When , the resource utilization rate of the Layer 2 sub-interface table is 90%; when the resource usage of the ARP table (that is, the number of ARP entries configured in the target network element) is 2000, and the resource specification of the ARP table is 2500 , the resource utilization rate of the ARP table is 80%; when the resource usage of the FIBv4 table (that is, the number of IPv4 routes configured in the target network element) is 1500, and the resource specification of the FIBv4 table is 2500, the resources of the FIBv4 table Utilization rate is 60%.

Table 8
步骤302，计算机设备根据目标资源的资源利用率评估目标网元的容量风险。Step 302: The computer device evaluates the capacity risk of the target network element based on the resource utilization of the target resource.
当目标资源的资源利用率满足风险条件时，计算机设备确定目标网元存在容量风险。具体地，计算机设备确定目标网元存在该目标资源容量风险，即，存在容量风险的资源为该目标资源。风险条件包括：目标资源的资源利用率大于利用率阈值，或者，目标资源的资源利用率连续大于利用率阈值的时长超过时长阈值，或者，目标资源的资源利用率连续大于利用率阈值的次数超过数量阈值。When the resource utilization rate of the target resource meets the risk condition, the computer device determines that the target network element has a capacity risk. Specifically, the computer device determines that the target network element has the target resource capacity risk, that is, the resource with the capacity risk is the target resource. Risk conditions include: the resource utilization of the target resource is greater than the utilization threshold, or the resource utilization of the target resource is continuously greater than the utilization threshold for more than the duration threshold, or the resource utilization of the target resource is continuously greater than the utilization threshold for more than a number of times. Quantity threshold.
例如，若目标资源为ARP表，若ARP表的利用率阈值为75％，则表8所示的ARP表的资源利用率(80％)大于ARP表的利用率阈值，计算机设备确定目标网元存在容量风险。具体地，计算机设备确定目标网元存在ARP表容量风险。For example, if the target resource is an ARP table and the utilization threshold of the ARP table is 75%, then the resource utilization (80%) of the ARP table shown in Table 8 is greater than the utilization threshold of the ARP table, and the computer device determines the target network element There is a capacity risk. Specifically, the computer device determines that the target network element has an ARP table capacity risk.
又例如，计算机设备周期性(例如，周期为5分钟)地计算目标网元的目标资源的资源利用率以获取目标资源的资源利用率序列。该资源利用率序列包括计算机设备先后获取到的目标网元的目标资源的资源利用率，当该序列中连续大于利用率阈值的资源利用率的个数超过数量阈值时，计算机设备确定该目标网元存在容量风险。例如，目标资源为ARP表，ARP表的利用率阈值为75％，数量阈值为4，ARP表的资源利用率序列为[70％，76％，85％，80％，90％，86％]，该序列中连续大于利用率阈值的资源利用率的数量为5，该数量超过数量阈值，计算机设备确定目标网元存在ARP表的容量风险。或者，计算机设备还可以将上述数量乘以周期时长，以获取目标资源的利用率连续大于利用率阈值的时长，当该时长超过时长阈值时，计算机确定目标网元存在目标资源的容量风险。For another example, the computer device periodically (for example, the cycle is 5 minutes) calculates the resource utilization of the target resource of the target network element to obtain the resource utilization sequence of the target resource. The resource utilization sequence includes the resource utilization of the target resources of the target network element that the computer device has successively acquired. When the number of resource utilizations in the sequence that are continuously greater than the utilization threshold exceeds the quantity threshold, the computer device determines that the target network There is a capacity risk. For example, the target resource is an ARP table, the utilization threshold of the ARP table is 75%, the quantity threshold is 4, and the resource utilization sequence of the ARP table is [70%, 76%, 85%, 80%, 90%, 86%] , the number of resource utilizations in the sequence that are continuously greater than the utilization threshold is 5. This number exceeds the quantity threshold, and the computer device determines that the target network element has a capacity risk in the ARP table. Alternatively, the computer device can also multiply the above number by the cycle duration to obtain the duration during which the utilization rate of the target resource is continuously greater than the utilization threshold. When the duration exceeds the duration threshold, the computer determines that the target network element has a capacity risk of the target resource.
可选地，当目标资源包括多个第一资源时，若存在至少一个第一资源满足风险条件， 则计算机设备确定目标网元存在容量风险，存在容量风险的资源为满足风险条件的至少一个第一资源。例如，如表8所示，目标资源包括VRF实例表、三层逻辑接口表、二层子接口表、ARP表和FIBv4表，若各个表项资源的风险阈值均为75％，则二层子接口表和ARP表的资源利用率均超过风险阈值，计算机设备可以确定该目标网元存在容量风险，具体地，计算机设备确定该目标网元的二层子接口表和ARP表存在容量风险。Optionally, when the target resource includes multiple first resources, if there is at least one first resource that meets the risk condition, Then the computer device determines that the target network element has a capacity risk, and the resource with the capacity risk is at least one first resource that meets the risk condition. For example, as shown in Table 8, the target resources include VRF instance table, Layer 3 logical interface table, Layer 2 sub-interface table, ARP table and FIBv4 table. If the risk threshold of each table entry resource is 75%, then the Layer 2 sub-interface table The resource utilization rates of the interface table and the ARP table both exceed the risk threshold, and the computer device can determine that the target network element has a capacity risk. Specifically, the computer device determines that the target network element's Layer 2 sub-interface table and ARP table have a capacity risk.
利用率阈值、数量阈值和时长阈值可以是预先配置的，也可以是计算机设备基于历史数据获取的。例如，计算机设备根据网络中的同一设备类型的多个网络设备发生业务故障时或发生业务故障前的一段时间内的各资源的资源使用量获取该设备类型的各资源的利用率阈值、数量阈值或时长阈值。例如，利用率阈值为业务故障发生时的多个资源使用量的统计值，数量阈值为业务故障发生前的连续大于利用率阈值的资源使用量的数量的统计值，时长阈值为业务故障发生前资源利用率连续大于利用率阈值的时长的统计值，统计值例如为均值、中位数、分位数等。The utilization threshold, quantity threshold and duration threshold can be pre-configured or obtained by the computer device based on historical data. For example, the computer device obtains the utilization threshold and quantity threshold of each resource of the device type based on the resource usage of each resource when multiple network devices of the same device type in the network have a business failure or during a period of time before the business failure occurs. or duration threshold. For example, the utilization threshold is the statistical value of multiple resource usage when a business failure occurs, the quantity threshold is the statistical value of the number of resource usage that is continuously greater than the utilization threshold before the business failure occurs, and the duration threshold is the statistical value of the resource usage before the business failure occurs. The statistical value of the length of time that the resource utilization is continuously greater than the utilization threshold. The statistical value is, for example, the mean, median, quantile, etc.

Further, the computer device can recommend handling suggestions for capacity risks. Optionally, after it is determined that the target network element has a capacity risk, the embodiment shown in Figure 3 may further include step 303 and/or step 304.
