技术领域Technical field

本申请涉及通信技术领域，尤其涉及一种网络切片资源管理方法及设备。This application relates to the field of communication technology, and in particular to a method and device for network slicing resource management.

背景技术Background technique

随着通信技术发展和网络业务的拓展，业务多样性和智能业务部署已经成为新一代通信***的必备特性。目前的业务场景丰富多样，例如增强移动宽带(enhance mobile broadband，eMBB)、以物联网为代表的海量机器类通信(massive machine type communications，mMTC)，以及超可靠低时延通信(ultra reliable low latency communications，URLLC)。当然，不同业务场景和不同的业务都对带宽、时延、可靠性和安全性等指标有着不同的需求，需要通信***提供多样化支持，为业务分配资源。With the development of communication technology and the expansion of network services, service diversity and intelligent service deployment have become indispensable features of the new generation of communication systems. The current business scenarios are rich and diverse, such as enhanced mobile broadband (eMBB), massive machine type communications (mMTC) represented by the Internet of Things, and ultra-reliable low latency communications (ultra reliable low latency) communications, URLLC). Of course, different business scenarios and different services have different requirements for indicators such as bandwidth, delay, reliability, and security. The communication system needs to provide diversified support and allocate resources for services.

为了向用户提供更完善的网络服务，新一代通信***可以将逻辑功能抽象为网络切片(network slice，NS)。网络切片技术能够在通用的物理基础设施上实现多个不同类型的网络应用，具体来说，网络切片技术是利用软件定义网络(software defined network，SDN)和网络功能虚拟化(network functions virtualization，NFV)等技术，将物理基础设施的资源虚拟化为多个相互独立且相互隔离的端到端的逻辑网络。In order to provide users with more complete network services, the new generation of communication systems can abstract logical functions into network slices (NS). Network slicing technology can implement multiple different types of network applications on a common physical infrastructure. Specifically, network slicing technology uses software defined network (SDN) and network functions virtualization (NFV). ) And other technologies to virtualize the resources of the physical infrastructure into multiple independent and isolated end-to-end logical networks.

其中，单个网络切片可以用来实现某一具体的业务场景，以满足和适应不同网络应用的类型和服务质量需求，如图1所示。具体的资源可以包括计算资源(例如中央处理器(central processing unit，CPU)、虚拟机(Virtual Machine，VM)，以及虚拟容器(container)等)、存储资源(例如内存资源和/或硬件存储资源)，网络资源(例如网络通信接口、网关设备、交换机、路由器等)等等。当将资源分配到不同的网络切片后，这些资源又可称为网络资源，或者通信资源。Among them, a single network slice can be used to implement a specific business scenario to meet and adapt to different network application types and service quality requirements, as shown in Figure 1. Specific resources may include computing resources (such as central processing unit (CPU), virtual machine (VM), and virtual container (container), etc.), storage resources (such as memory resources and/or hardware storage resources) ), network resources (such as network communication interfaces, gateway devices, switches, routers, etc.), etc. After resources are allocated to different network slices, these resources can also be called network resources or communication resources.

由于网络切片技术构建在资源虚拟化之上，所以资源管理是管理网络切片的核心。目前的资源管理方法通常是以单一的网络资源作为优化的对象，这样的优化方法不灵活，直接应用到对网络切片的资源管理上，效果并不理想。因此，寻找一种灵活地网络切片资源管理方法是本领域技术人员亟待解决的问题。Because network slicing technology is built on resource virtualization, resource management is the core of managing network slicing. Current resource management methods usually take a single network resource as the object of optimization. Such optimization methods are not flexible and are directly applied to the resource management of network slicing, and the effect is not ideal. Therefore, finding a flexible network slicing resource management method is an urgent problem to be solved by those skilled in the art.

Finally, the management The device separately manages the resources of the n network slices according to the obtained resource management policies respectively corresponding to the n network slices. Wherein, the resource information of any network slice is used to indicate the allocation information and usage information of multiple resources of the network slice, and n is an integer greater than or equal to 1. The resource management policy model is used to represent the mapping relationship between the resource information of the n network slices and the resource management policies respectively corresponding to the n network slices.

在以上方法中，管理设备根据获得的n个网络切片的资源信息，以及资源管理策略模型，可以快速的得到所述n个网络切片的资源管理策略。由于在本方案中，所述n个网络切片的资源信息能够准确描述n个网络切片的对多种资源的资源利用情况，因此，该方法可以根据网络切片对多种资源的资源利用情况实现网络切片的资源管理，从而可以提高网络切片的资源管理灵活性。另外，由于该方法可以综合考虑多个网络切片的资源利用情况，因此，通过该方法确定的所述n个网络切片的资源管理策略能够实现网络中各个网络切片的资源优化，即该方法可以在保证各个网络切片的网络性能的同时，实现全网的资源优化。In the above method, the management device can quickly obtain the resource management strategy of the n network slices according to the obtained resource information of the n network slices and the resource management strategy model. Since in this solution, the resource information of the n network slices can accurately describe the resource utilization of the n network slices for multiple resources, this method can realize the network according to the resource utilization of the network slices for multiple resources. The resource management of slices can improve the flexibility of resource management of network slices. In addition, because this method can comprehensively consider the resource utilization of multiple network slices, the resource management strategy of the n network slices determined by this method can realize the resource optimization of each network slice in the network, that is, the method can be used in While ensuring the network performance of each network slice, the resource optimization of the entire network is realized.

在一个可能的设计中，所述n个网络切片为所述NFV架构中的全部或部分网络切片。In a possible design, the n network slices are all or part of the network slices in the NFV architecture.

在一个可能的设计中，所述管理设备可以周期性获取所述n个网络切片的资源信息。这样，所述管理设备可以通过周期性的获取所述n个网络切片的资源信息，实现周期性的对所述n个网络切片的资源管理和资源调度。In a possible design, the management device may periodically obtain the resource information of the n network slices. In this way, the management device can periodically obtain resource information of the n network slices to implement resource management and resource scheduling of the n network slices periodically.

在一个可能的设计中，所述管理设备在接收到所述n个网络切片中至少一个网络切片发送的资源重配请求后，获取所述多个网络切片的资源信息。In a possible design, the management device obtains the resource information of the multiple network slices after receiving the resource reconfiguration request sent by at least one network slice among the n network slices.

例如，所述资源重配请求可以为任一网络切片检测到自身的资源需求信息发生变化时发送的。这样，所述管理设备可以根据所述网络切片的当前的资源使用情况和整个网络的资源使用情况，重新为所述网络切片(和其他网络切片)进行资源调度，从而保证所述网络切片(和其他网络切片)的资源能够满足当前业务对资源的需求，也可以保证所述网络切片(和其他网络切片)的资源的利用率，避免资源空闲。For example, the resource reconfiguration request may be sent when any network slice detects that its resource requirement information has changed. In this way, the management device can perform resource scheduling for the network slice (and other network slices) again according to the current resource usage of the network slice and the resource usage of the entire network, thereby ensuring the network slice (and The resources of other network slices can meet the resource requirements of current services, and can also ensure the utilization of the resources of the network slices (and other network slices) to avoid resource idleness.

又例如，所述资源重配置请求也可以为任一网络切片确定自身的至少一种资源的剩余量小于设定第一剩余量阈值，或剩余率小于设定第一剩余率阈值，或者利用率大于设定第一利用率阈值时发送的。这样，所述管理设备可以重新为所述网络切片进行资源调度，为所述网络切片分配更多的资源，避免由于资源不足影响所述网络切片的网络性能和业务实现。For another example, the resource reconfiguration request may also determine for any network slice that the remaining amount of at least one of its own resources is less than the set first remaining amount threshold, or the remaining rate is less than the set first remaining rate threshold, or the utilization rate Sent when the first utilization rate threshold is set. In this way, the management device can perform resource scheduling for the network slice again, allocate more resources for the network slice, and avoid affecting the network performance and service realization of the network slice due to insufficient resources.

再例如，所述资源重配置请求还可以为任一网络切片确定自身的至少一种资源的剩余量大于设定第二剩余量阈值，或剩余率大于设定第二剩余率阈值，或者利用率小于设定第二利用率阈值时发送的。这样，所述管理设备可以重新为所述网络切片进行资源调度，将分配给所述网络切片的资源调配给其他网络切片或放回待分配的资源池中，避免网络资源长期被部分网络切片占用但利用率较低，从而保证在多网络切片场景下资源利用的公平性，从而可以提高资源的利用率。For another example, the resource reconfiguration request may also determine for any network slice that the remaining amount of at least one of its own resources is greater than the set second remaining amount threshold, or the remaining rate is greater than the set second remaining rate threshold, or the utilization rate Sent when it is less than the second utilization threshold. In this way, the management device can perform resource scheduling for the network slice again, and allocate the resources allocated to the network slice to other network slices or put it back into the resource pool to be allocated, so as to avoid long-term occupation of network resources by some network slices. However, the utilization rate is low, so as to ensure the fairness of resource utilization in the multi-network slicing scenario, thereby improving resource utilization.

在一个可能的设计中，所述管理设备在接收到用户输入的资源管理指令后，获取所述n个网络切片的资源信息。这样，用户可以控制网络切片的资源管理和调度，提高网络切片的资源管理的灵活性。In a possible design, the management device obtains the resource information of the n network slices after receiving the resource management instruction input by the user. In this way, the user can control the resource management and scheduling of the network slice, and improve the flexibility of the resource management of the network slice.

在一个可能的设计中，所述管理设备监测所述n个网络切片的资源需求信息，当所述管理设备确定所述多个网络切片中至少一个网络切片的资源需求信息发生变化后，获取所述多个网络切片的资源信息。In a possible design, the management device monitors the resource demand information of the n network slices, and when the management device determines that the resource demand information of at least one of the plurality of network slices has changed, obtains all Describe resource information of multiple network slices.

通过该设计，所述管理设备可以根据所述网络切片的当前的资源使用情况和整个网络的资源使用情况，重新为所述网络切片进行资源调度，从而保证所述网络切片的资源能够满足当前业务对资源的需求，也可以保证所述网络切片的资源的利用率，避免资源空闲。Through this design, the management device can re-schedule the network slice according to the current resource usage of the network slice and the resource usage of the entire network, thereby ensuring that the resources of the network slice can meet the current service requirements. The demand for resources can also ensure the utilization rate of the resources of the network slice and avoid resource idleness.

在一个可能的设计中，任一个网络切片的资源需求信息包括以下任一项或组合：接入所述网络切片的终端设备的数量、所述网络切片的服务质量QoS，所述网络切片的业务类型。这样，网络切片的资源需求信息可以准确地体现出网络切片的资源需求。In a possible design, the resource requirement information of any network slice includes any one or a combination of the following: the number of terminal devices that access the network slice, the quality of service QoS of the network slice, and the service of the network slice Types of. In this way, the resource demand information of the network slicing can accurately reflect the resource demand of the network slicing.

在一个可能的设计中，任一个网络切片的资源信息中包含：第一资源信息：每个物理节点中分配给所述网络切片的每种资源的分配信息，和所述网络切片对每个物理节点中的每种资源的使用信息；和/或，第二资源信息：分配给所述网络切片中每个虚拟网络功能VNF的每种资源的分配信息，和所述网络切片中每个VNF对每种资源的使用信息；其中，每个物理节点为所述网络切片中的VNF占用的。In a possible design, the resource information of any network slice includes: first resource information: the allocation information of each resource allocated to the network slice in each physical node, and the network slice for each physical node Usage information of each resource in the node; and/or second resource information: allocation information of each resource allocated to each virtual network function VNF in the network slice, and each VNF pair in the network slice Usage information of each resource; wherein, each physical node is occupied by the VNF in the network slice.

通过该设计，第一资源信息不仅可以充分体现出网络切片的资源利用情况，还可以体现出整个网络的资源利用情况。第二资源信息不仅可以充分体现出网络切片的资源利用情况，还可以进一步体现网络切片中每个VNF的资源利用情况。由于对网络切片的资源利用情况的描述的准确性在很大程度上会影响资源管理调度结果的优劣。因此，通过本设计中的第一资源信息和/或第二资源信息，可以准确地描述网络切片对多种资源的资源利用情况，从而可以进一步保证所述管理设备按照后续确定的所述n个网络切片的资源管理策略能够实现网络中各个网络切片的资源优化。Through this design, the first resource information can not only fully reflect the resource utilization of the network slice, but also reflect the resource utilization of the entire network. The second resource information can not only fully reflect the resource utilization of the network slice, but also further reflect the resource utilization of each VNF in the network slice. Because the accuracy of the description of the resource utilization of the network slicing will largely affect the quality of the resource management scheduling results. Therefore, the first resource information and/or the second resource information in this design can accurately describe the resource utilization of multiple resources by the network slicing, thereby further ensuring that the management device is in accordance with the subsequent determined n The resource management strategy of network slicing can realize the resource optimization of each network slice in the network.

当任一个网络切片的资源信息中包含上述第一资源信息时，所述管理设备可以根据物理节点中网络切片对每种资源的使用情况生成资源管理策略，以保证资源管理策略符合每个物理节点中资源的种类和数量的限定，使资源管理策略能够物理实现，即所述管理设备可以根据资源管理策略成功为网络切片分配资源。When the resource information of any network slice contains the above-mentioned first resource information, the management device may generate a resource management strategy according to the usage of each resource in the network slice in the physical node to ensure that the resource management strategy conforms to each physical node The limitation of the type and quantity of resources in the medium enables the physical realization of the resource management strategy, that is, the management device can successfully allocate resources for the network slice according to the resource management strategy.

当任一个网络切片的资源信息中包含上述第二资源信息时，所述管理设备可以根据网络切片中每个VNF对资源的使用情况生成资源管理策略，可以将资源管理策略细化到VNF，保证每个VNF的功能实现的同时，还可以改善和优化每个VNF的资源利用率，进而可以改善和优化网络切片的资源利用率和端到端网络性能。When the resource information of any network slice contains the above-mentioned second resource information, the management device can generate a resource management strategy according to the resource usage of each VNF in the network slice, and can refine the resource management strategy to the VNF to ensure While the function of each VNF is realized, it can also improve and optimize the resource utilization rate of each VNF, which in turn can improve and optimize the resource utilization rate and end-to-end network performance of network slicing.

在一个可能的设计中，所述资源管理策略模型是对所述n个网络切片的资源信息样本数据，以及所述n个网络切片的资源管理策略样本数据进行建模得到的。通过该设计，所述管理设备可以通过所述资源管理策略模块，快速且准确地得到所述n个网络切片分别对应的资源管理策略，提高所述管理设备的对网络切片进行资源管理的效率。In a possible design, the resource management strategy model is obtained by modeling resource information sample data of the n network slices and resource management strategy sample data of the n network slices. Through this design, the management device can quickly and accurately obtain resource management policies corresponding to the n network slices through the resource management strategy module, thereby improving the efficiency of the management device for resource management of the network slices.

在一个可能的设计中，在所述管理设备根据所述n个网络切片分别对应的资源管理策略，分别对所述n个网络切片的资源进行管理之后，所述管理设备计算所述n个网络切片的网络性能；并在当所述管理设备确定所述n个网络切片中任一个网络切片的网络性能低于所述网络切片的设定网络性能门限时，调整所述n个网络切片分别对应的资源管理策略，并重新根据调整后的所述n个网络切片分别对应的资源管理策略，分别对所述n个网络切片的资源进行管理，以及重新计算所述n个网络切片的网络性能，直至确定所述n个网络切片中每个网络切片的网络性能达到相应的设定网络性能门限为止。In a possible design, after the management device separately manages the resources of the n network slices according to the resource management policies corresponding to the n network slices, the management device calculates the n network slices Network performance of the slice; and when the management device determines that the network performance of any one of the n network slices is lower than the set network performance threshold of the network slice, adjust the n network slices to correspond to According to the resource management strategy of the n network slices, respectively, according to the adjusted resource management strategy corresponding to the n network slices, the resources of the n network slices are respectively managed, and the network performance of the n network slices is recalculated, Until it is determined that the network performance of each of the n network slices reaches the corresponding set network performance threshold.

通过该设计，所述管理设备可以通过所述n个网络切片的网络性能对所述n个网络切片分别对应的资源管理策略的有效性进行验证，在验证不通过时，还可以重新对所述n个网络切片分别对应的资源管理策略进行调整，以保证最后生成的所述n个网络切片分别对应的资源管理策略能够实现网络中各个网络切片的资源优化，即该方法可以在保证各个网络切片的网络性能的同时，实现全网的资源优化。Through this design, the management device can verify the validity of the resource management policies corresponding to the n network slices through the network performance of the n network slices, and can also re-check the resource management policies when the verification fails. The resource management strategies corresponding to the n network slices are adjusted to ensure that the resource management strategies corresponding to the n network slices finally generated can realize the resource optimization of each network slice in the network, that is, the method can ensure that each network slice While achieving high network performance, the resource optimization of the entire network is realized.

另外，由于所述管理设备根据通过所述资源管理策略模型计算得到的所述n个网络切片分别对应的资源管理策略，不能使所述n个网络切片的网络性能达到所述网络性能门限，表示所述资源管理策略模块还需要进一步训练和调整。因此，在上述步骤后，所述管理设备可以将所述n个网络切片的资源信息以及最后调整得到的所述n个网络切片分别对应的资源管理策略作为样本数据，用于后续对所述资源管理策略模型进行训练或测试。In addition, since the management device calculates according to the resource management policies corresponding to the n network slices calculated by the resource management policy model, the network performance of the n network slices cannot reach the network performance threshold, which means The resource management strategy module needs further training and adjustment. Therefore, after the above steps, the management device may use the resource information of the n network slices and the finally adjusted resource management policies corresponding to the n network slices as sample data for subsequent analysis of the resource The management strategy model is trained or tested.

在一个可能的设计中，所述管理设备还可以根据所述n个网络切片的优先级，所述n个网络切片的资源信息，以及存储的资源管理策略模型，得到所述n个网络切片分别对应的资源管理策略。该设计可以实现对网络切片的差分化资源管理和调度。In a possible design, the management device may also obtain the n network slices according to the priority of the n network slices, the resource information of the n network slices, and the stored resource management policy model. The corresponding resource management strategy. This design can realize differentiated resource management and scheduling of network slices.

例如，当所述管理设备按照所述n个网络切片的资源信息的先后顺序进行资源管理调度时，优先为资源信息在先的网络切片进行资源调度。这样，所述管理设备在得到所述n个网络切片的资源信息后，先按照所述n个网络切片的优先级对所述n个网络切片的资源信息进行排序，将优先级在前的网络切片的资源信息排在前面，然后，在将排序后的所述n个网络切片的资源信息输入到所述资源管理策略模型中，得到所述n个网络切片分别对应的资源管理策略。For example, when the management device performs resource management scheduling according to the sequence of the resource information of the n network slices, priority is given to the network slice with the first resource information to perform resource scheduling. In this way, after obtaining the resource information of the n network slices, the management device first sorts the resource information of the n network slices according to the priority of the n network slices, and sorts the network with the first priority. The resource information of the slices is ranked first, and then the sorted resource information of the n network slices are input into the resource management policy model to obtain resource management policies corresponding to the n network slices respectively.

另外，可选的，在本申请实施例中，在所述资源管理策略模型中设置为优先级最高的待管理网络切片的优先进行资源调度，具体可以但不限于包括以下几种方式：In addition, optionally, in the embodiment of the present application, the resource scheduling is set as the priority of the network slice to be managed with the highest priority in the resource management policy model, which may specifically include but is not limited to the following methods:

方式一：在空闲资源足够的情况下，管理设备优先为该网络切片进行资源分配，以满足该网络切片的资源需求。Manner 1: In the case of sufficient idle resources, the management device preferentially allocates resources for the network slice to meet the resource requirements of the network slice.

方式二：在空闲资源不足的情况下，管理设备将优先级最低的网络切片的资源调配给该网络切片，或者优先对该网络切片的虚拟机进行迁移，以满足该网络切片的资源需求。例如，当该网络切片所占用的物理节点A出现过载情况，无法通过调度释放该网络切片所需的资源时，优先将该网络切片的虚拟机迁移到空闲资源充足的物理节点B中。Manner 2: In the case of insufficient idle resources, the management device allocates the resources of the network slice with the lowest priority to the network slice, or preferentially migrates the virtual machines of the network slice to meet the resource requirements of the network slice. For example, when the physical node A occupied by the network slice is overloaded and the resources required by the network slice cannot be released through scheduling, the virtual machine of the network slice is preferentially migrated to the physical node B with sufficient idle resources.

方式三：管理设备确定影响该网络切片的网络性能最主要的资源种类，优先为该网络切片分配该种资源。Manner 3: The management device determines the most important resource type that affects the network performance of the network slice, and preferentially allocates this resource to the network slice.

For example, the resource management policy of any network slice includes: in the order from the user side to the service side, or from the service side to the user side, scheduling actions for each resource of each VNF in the network slice. In this way, the management device can use the resource management strategy of each network slice to schedule the resources of each VNF in each network slice, ensuring that the functions of each VNF are realized, while improving and optimizing each network slice. The resource utilization rate of a VNF can then improve and optimize the end-to-end network performance and resource optimization of the entire network slicing to achieve the network performance and resource optimization of the entire network.

Referring to Figure 3, the process of the method includes:

S301：管理设备获取n个网络切片的资源信息，其中任一个网络切片的资源信息用于表示所述网络切片的多种资源分配信息和使用信息，n为大于或等于1的整数。S301: The management device obtains resource information of n network slices, where the resource information of any network slice is used to indicate multiple resource allocation information and usage information of the network slice, and n is an integer greater than or equal to 1.

其中，所述n个网络切片为所述NFV架构中的全部或部分网络切片。将n个网络切片中的任一个网络切片用“目标网络切片”表示，则目标网络切片的资源信息中可以但不限于包含：Wherein, the n network slices are all or part of the network slices in the NFV architecture. If any one of the n network slices is represented by "target network slice", the resource information of the target network slice may include but is not limited to:

第一资源信息：每个物理节点中分配给所述目标网络切片的每种资源的分配信息，和所述目标网络切片对每个物理节点中的每种资源的使用信息，其中，每个物理节点为所述目标网络切片中的VNF占用的物理节点；和/或，第二资源信息：分配给所述目标网络切片中每个VNF的每种资源的分配信息，和所述目标网络切片中每个VNF对每种资源的使用信息。First resource information: allocation information of each resource in each physical node allocated to the target network slice, and usage information of each resource in each physical node by the target network slice, where each physical node A node is a physical node occupied by a VNF in the target network slice; and/or, second resource information: the allocation information of each resource allocated to each VNF in the target network slice, and the information in the target network slice Each VNF uses information of each resource.

通过上述两种资源信息的描述可知，第一资源信息不仅可以充分体现出网络切片的资源利用情况，还可以体现出整个网络的资源利用情况。第二资源信息不仅可以充分体现出网络切片的资源利用情况，还可以进一步体现网络切片中每个VNF的资源利用情况。From the description of the above two kinds of resource information, it can be seen that the first resource information can not only fully reflect the resource utilization of the network slice, but also reflect the resource utilization of the entire network. The second resource information can not only fully reflect the resource utilization of the network slice, but also further reflect the resource utilization of each VNF in the network slice.

众所周知，准确地描述网络切片的资源利用情况，是对网络切片进行资源调度和管理的基础，且对网络切片的资源利用情况的描述的准确性在很大程度上会影响资源管理调度结果的优劣。因此，通过以上第一资源信息和/或第二资源信息，可以准确地描述网络切片对多种资源的资源利用情况，从而可以进一步保证所述管理设备按照后续确定的所述n个网络切片的资源管理策略能够实现网络中各个网络切片的资源优化。As we all know, accurately describing the resource utilization of network slicing is the basis for resource scheduling and management of network slicing, and the accuracy of the description of the resource utilization of network slicing will greatly affect the optimization of resource management scheduling results. inferior. Therefore, through the above first resource information and/or second resource information, it is possible to accurately describe the resource utilization situation of multiple resources by the network slice, thereby further ensuring that the management device follows the subsequently determined n network slices. Resource management strategy can realize the resource optimization of each network slice in the network.

当任一个网络切片的资源信息中包含上述第一资源信息时，还可以进一步包含以下任一项或组合：每个物理节点在所述目标网络切片中的标识(后续可以简称为“切片标识”)，每个物理节点在物理基础设施(或网络)中的标识(后续可以简称为“节点标识”)，每个物理节点的调度标记。其中，任一个物理节点的切片标识可以标记该物理节点在目标网络切片中的位置，任一个物理节点的节点标识可以标记该物理节点在物理基础设施或网络中的位置。任一个物理节点的调度标记用于标记该物理节点是否允许资源调度，或者之前对该物理节点的资源的调度动作，或者该物理节点允许的调度动作等信息。通过添加切片标识和节点标识，可以明确目标网络切片中的VNF在网络拓扑中的位置，从而根据该信息观察在网络切片维度和物理节点维度上资源利用情况，从而实现以全网内的网络切片端到端的资源优化。When the resource information of any network slice includes the above-mentioned first resource information, it may further include any one or a combination of the following: the identification of each physical node in the target network slice (hereinafter may be referred to as "slice identification" for short) ), the identification of each physical node in the physical infrastructure (or network) (hereinafter may be referred to as "node identification" for short), and the scheduling mark of each physical node. Wherein, the slice identifier of any physical node may mark the position of the physical node in the target network slice, and the node identifier of any physical node may mark the position of the physical node in the physical infrastructure or network.

在实际应用中，由于不同网络切片所承载的业务不同，因此，不同的网络切片的都有其特殊资源需求和服务优先级。为了实现对网络切片的差分化资源管理和调度，本申请实施例提出了网络切片的优先级的概念。其中，网络切片的优先级是根据网络切片的业务类型和特点，以及网络切片对资源的需求情况综合考虑确定的。其中，网络切片的业务类型和特点可以为延迟、带宽、移动性和可靠性等方面。In practical applications, because different network slices carry different services, different network slices have their special resource requirements and service priorities. In order to implement differentiated resource management and scheduling for network slices, the embodiment of the present application proposes the concept of priority of network slices. Among them, the priority of the network slicing is determined by comprehensive consideration of the service types and characteristics of the network slicing and the resource requirements of the network slicing. Among them, the service types and characteristics of network slicing can be delay, bandwidth, mobility, and reliability.

例如，当前网络中存在工业控制网络切片、车联网网络切片、高清视频网络切片三个承载具体业务的网络切片。首先上述三个网络切片的业务类型和特点为：工业控制网络切片占用的计算和传输带宽资源少，但是对可靠性要求极高；车联网网络切片要求对计算资源需求量大且对延时也要较高要求；高清视频网络切片占用大量的传输带宽资源，但是对可靠性的容忍度较大。另外，上述三个网络切片对资源的需求情况为：工业控制网络切片和车联网网络切片的资源需求小，利用率高；高清视频网络切片的资源需求大，但利用率变化水平较大。结合以上两方面信息，管理设备或其他具有优先级确定功能的功能单元/模块可以确定上述三个网络切片的优先级，如图4所示。For example, there are three network slices that carry specific services in the current network: industrial control network slice, car networking network slice, and high-definition video network slice. First of all, the service types and characteristics of the above three network slices are: industrial control network slices occupy less computing and transmission bandwidth resources, but have extremely high requirements for reliability; car networking network slices require a large amount of computing resources and also have a great impact on delay. Higher requirements; high-definition video network slicing occupies a large amount of transmission bandwidth resources, but has a greater tolerance for reliability. In addition, the resource requirements of the above three network slices are: industrial control network slices and car networking network slices have small resource requirements and high utilization rates; high-definition video network slices have large resource requirements, but the utilization rate varies greatly. Combining the above two aspects of information, the management device or other functional unit/module with priority determination function can determine the priority of the above three network slices, as shown in Figure 4.

综上，为了实现对网络切片的差分化资源管理和调度，在一个实现方式中，所述管理设备还可以根据所述n个网络切片的优先级，所述n个网络切片的资源信息，以及存储的资源管理策略模型，得到所述n个网络切片分别对应的资源管理策略。In summary, in order to implement differentiated resource management and scheduling for network slices, in one implementation, the management device may also be based on the priority of the n network slices, the resource information of the n network slices, and The stored resource management policy model obtains the resource management policies corresponding to the n network slices respectively.

在本申请实施例中，在所述资源管理策略模型中设置的为优先级最高的待管理网络切片的优先进行资源调度，具体可以但不限于包括以下几种方式：In the embodiment of the present application, the resource scheduling for the network slice to be managed with the highest priority set in the resource management policy model may specifically include but not limited to the following methods:

还需要说明的是，在本申请实施例中，任一个网络切片的资源管理策略中包含对至少一种资源的调度动作。在一个实现方式中，任一个网络切片的资源管理策略中包含：按照从用户侧向服务侧，或者从服务侧到用户侧的顺序，对该网络切片中每个VNF的每种资源的调度动作。通过这种方式，所述管理设备可以通过每个网络切片的资源管理策略，每个网络切片中的每个VNF的资源得到调度，保证每个VNF的功能实现的同时，还可以改善和优化每个VNF的资源利用率，进而改善和优化整个网络切片端到端的网络性能和资源优化，达到全网的网络性能和资源优化。It should also be noted that in this embodiment of the present application, the resource management strategy of any network slice includes a scheduling action for at least one resource. In one implementation, the resource management strategy of any network slice includes: in the order from the user side to the service side, or from the service side to the user side, the scheduling actions for each resource of each VNF in the network slice . In this way, the management device can use the resource management strategy of each network slice to schedule the resources of each VNF in each network slice, ensuring that the functions of each VNF are realized, while improving and optimizing each network slice. The resource utilization rate of a VNF can then improve and optimize the end-to-end network performance and resource optimization of the entire network slicing to achieve the network performance and resource optimization of the entire network.

例如，NFV架构中包含网络切片1和网络切片2，其中，网络切片1中包含：VNF 1-1，VNF 1-2和VNF 1-3，网络切片2中包含：VNF2-1和VNF2-2。所述管理设备获取的网络切片1的资源信息可以通过以下数组1表示，网络切片2的资源信息可以通过以下数组2表示：For example, the NFV architecture includes network slice 1 and network slice 2. Among them, network slice 1 includes: VNF 1-1, VNF 1-2, and VNF 1-3, and network slice 2 includes: VNF2-1 and VNF2-2 . The resource information of the network slice 1 obtained by the management device may be represented by the following array 1, and the resource information of the network slice 2 may be represented by the following array 2:

数组1：

Array 1:

数组2：

Array 2:

其中，数组中的每一行代表网络切片中的一个VNF的资源信息，以数组1中的第一行为例，J _1-1代表分配给VNF 1-1的计算资源总量，C _{1_1}代表分配给VNF 1-1的存储资源总量，W _{1_1}代表分配给VNF 1-1的网络资源总量，后面依次是VNF 1-1对计算资源、存储资源和网络资源的平均使用率。 Among them, each row in the array represents the resource information of a VNF in the network slice. Taking the first row in array 1, as an example, J _1-1 represents the total amount of computing resources allocated to VNF 1-1, and C _{1_1} represents The total amount of storage resources of VNF 1-1, W _{1_1} represents the total amount of network resources allocated to VNF 1-1, followed by VNF 1-1's average utilization rate of computing resources, storage resources, and network resources.

所述管理设备将如数组1和数组2所示的两个网络切片的资源信息输入到所述资源管理策略模型中，可以得到网络切片1和网络切片2的资源管理策略。The management device inputs the resource information of the two network slices shown in the array 1 and the array 2 into the resource management policy model, and the resource management policies of the network slice 1 and the network slice 2 can be obtained.

网络切片1的资源管理策略为：The resource management strategy of network slice 1 is:

对VNF 1-1：计算资源不变，存储资源扩容10％，网络资源扩容10％；For VNF 1-1: Computing resources remain unchanged, storage resources are expanded by 10%, and network resources are expanded by 10%;

对VNF 1-2：计算资源缩容10％，存储资源不变，网络资源扩容10％；For VNF 1-2: computing resources are reduced by 10%, storage resources are unchanged, and network resources are expanded by 10%;

对VNF 1-3：计算资源缩容30％，存储资源扩容20％，网络资源不变。For VNF 1-3: computing resources are reduced by 30%, storage resources are expanded by 20%, and network resources remain unchanged.

网络切片2的资源管理处理为：The resource management processing of network slice 2 is:

对VNF 2-1：计算资源缩容10％，存储资源不变，网络资源缩容20％；For VNF 2-1: computing resources are reduced by 10%, storage resources are unchanged, and network resources are reduced by 20%;

对VNF 2-2：计算资源扩容20％，存储资源扩容20％，网络资源缩容40％。For VNF 2-2: 20% expansion of computing resources, 20% expansion of storage resources, and 40% reduction of network resources.

S303：所述管理设备根据所述n个网络切片分别对应的资源管理策略，分别对所述n个网络切片的资源进行管理。S303: The management device separately manages the resources of the n network slices according to the resource management policies respectively corresponding to the n network slices.

通过以上描述可知，任一个网络切片的资源管理策略中可以包含按照从用户侧向服务侧，或者从服务侧到用户侧的顺序，对该网络切片中每个VNF的每种资源的调度动作，因此，所述管理设备在执行S303时，就按照从用户侧到服务侧的顺序或者从服务侧到用户侧的顺序，依次对该网络切片中每个VNF的每个资源执行相应的调度动作，最终实现对该网络切片的资源管理。From the above description, it can be seen that the resource management strategy of any network slice may include scheduling actions for each resource of each VNF in the network slice in the order from the user side to the service side, or from the service side to the user side. Therefore, when the management device executes S303, it executes corresponding scheduling actions in sequence from the user side to the service side or from the service side to the user side for each resource of each VNF in the network slice. Finally realize the resource management of the network slice.

在一个实现方式中，所述管理设备在S303之后，所述管理设备还可以计算所述n个网络切片的网络性能；当所述管理设备确定所述n个网络切片中任一个网络切片的网络性能低于该网络切片的设定网络性能门限时，调整所述n个网络切片分别对应的资源管理策略，并重新根据调整后的所述n个网络切片分别对应的资源管理策略，分别对所述n个网络切片的资源进行管理，以及重新计算所述n个网络切片的网络性能，直至确定所述n个网络切片中每个网络切片的网络性能达到相应的设定网络性能门限为止。需要说明的是，在本申请实施例中，不同网络切片的设定网络性能门限可以相同，也可以不同，本申请对此不作限定。In an implementation manner, after the management device S303, the management device may also calculate the network performance of the n network slices; when the management device determines the network of any one of the n network slices When the performance is lower than the set network performance threshold of the network slice, the resource management policies corresponding to the n network slices are adjusted, and the resource management policies corresponding to the n network slices after adjustment are adjusted to each The resources of the n network slices are managed, and the network performance of the n network slices are recalculated until it is determined that the network performance of each of the n network slices reaches a corresponding set network performance threshold. It should be noted that in this embodiment of the present application, the set network performance thresholds for different network slices may be the same or different, which is not limited in this application.

由于所述管理设备根据通过所述资源管理策略模型计算得到的所述n个网络切片分别对应的资源管理策略，不能使所述n个网络切片的网络性能达到所述网络性能门限，表示所述资源管理策略模块还需要进一步训练和调整。因此，在上述步骤后，所述管理设备可以将所述n个网络切片的资源信息以及最后调整得到的所述n个网络切片的资源管理策略作为样本数据，用于后续对所述资源管理策略模型继续进行训练或测试。Since the management device calculates according to the resource management policies corresponding to the n network slices calculated by the resource management policy model, the network performance of the n network slices cannot reach the network performance threshold, indicating that the The resource management strategy module needs further training and adjustment. Therefore, after the above steps, the management device may use the resource information of the n network slices and the finally adjusted resource management strategy of the n network slices as sample data for subsequent management of the resource strategy The model continues to be trained or tested.

本申请实施例提供了一种网络切片资源管理方法，在该方法中，管理设备根据获得的n个网络切片的资源信息，以及资源管理策略模型，可以快速地得到所述n个网络切片分别对应的资源管理策略。由于在本方案中，所述n个网络切片的资源信息能够准确描述n个网络切片的对多种资源的资源利用情况，因此，该方法可以根据网络切片对多种资源的资源利用情况实现网络切片的资源管理，从而可以提高网络切片的资源管理灵活性。另外，由于该方法可以综合考虑多个网络切片的资源利用情况，因此，通过该方法确定的所述n个网络切片分别对应的资源管理策略能够实现网络中各个网络切片的资源优化，即该方法可以在保证各个网络切片的网络性能的同时，实现全网的资源优化。The embodiment of the present application provides a network slice resource management method. In this method, the management device can quickly obtain the n network slices corresponding to each of the n network slices according to the obtained resource information of the n network slices and the resource management policy model. Resource management strategy. Since in this solution, the resource information of the n network slices can accurately describe the resource utilization of the n network slices for multiple resources, this method can realize the network according to the resource utilization of the network slices for multiple resources. The resource management of slices can improve the flexibility of resource management of network slices. In addition, because this method can comprehensively consider the resource utilization of multiple network slices, the resource management strategies corresponding to the n network slices determined by this method can realize the resource optimization of each network slice in the network, that is, this method It can realize the resource optimization of the entire network while ensuring the network performance of each network slice.

本申请实施例还提供了一种网络切片资源管理***架构，该***中的模块是按照在上述实施例中的网络切片资源管理方法中的管理设备和相关功能单元/模块的逻辑功能划分的。参阅图5所示，该***中包含：调度动作生成模块501、资源管理策略模型生成模块502、网络性能计算模块503、资源信息获取模块504、网络切片的优先级确定模块505，以及资源管理模块506。下面对各个模块的功能进行详细描述。The embodiment of the present application also provides a network slice resource management system architecture. The modules in the system are divided according to the logical functions of the management device and related functional units/modules in the network slice resource management method in the foregoing embodiment. Referring to FIG. 5, the system includes: a scheduling action generation module 501, a resource management strategy model generation module 502, a network performance calculation module 503, a resource information acquisition module 504, a network slice priority determination module 505, and a resource management module 506. The function of each module is described in detail below.

调度动作生成模块501，用于生成当前***中对网络切片各种资源进行资源管理调度时的调度动作集合，以便资源管理策略模型生成模块502可以根据调度动作集合中的调度动作生成资源管理策略。The scheduling action generating module 501 is configured to generate a scheduling action set when resource management scheduling is performed on various resources of the network slice in the current system, so that the resource management policy model generating module 502 can generate a resource management policy according to the scheduling actions in the scheduling action set.

由于在本申请实施例中可以对多个网络切片进行资源调度，且每个网络切片的资源管理策略中包含对每种资源的调度动作，或者对该网络切片中的每个VNF的每种资源的调度动作，若调度动作为连续型调度动作(即调度动作中的数据为连续型数据)的话，则最终生成的多个网络切片的资源管理策略中的调度动作是以指数的数量级增加的。并且，由于调度动作数量巨大，这些调度动作无法用于资源管理策略模型的训练。Because in the embodiment of the present application, resource scheduling can be performed on multiple network slices, and the resource management strategy of each network slice includes the scheduling action for each resource, or each resource of each VNF in the network slice. If the scheduling action is a continuous scheduling action (that is, the data in the scheduling action is continuous data), the scheduling action in the resource management strategy of the multiple network slices finally generated increases by an exponential order of magnitude. Moreover, due to the huge number of scheduling actions, these scheduling actions cannot be used for training resource management strategy models.

在一个实现方式中，所述调度动作生成模块501可以根据当前***中设置的资源调度精度和资源调度变化范围，将连续型调度动作转换为离散型调度动作(即调度动作中的数据为离散型数据)。例如，资源调度变化范围为缩容(增加)60％～扩容(减少)60％，资源调度精度为20％，那么所述调度动作生成模块501生成的资源调度动作集合为：缩容60％，缩容40％，缩容20％，容量保持不变，扩容20％，扩容40％，扩容60％。In one implementation, the scheduling action generating module 501 can convert a continuous scheduling action to a discrete scheduling action (that is, the data in the scheduling action is a discrete scheduling action according to the resource scheduling accuracy and resource scheduling change range set in the current system. data). For example, the resource scheduling change range is 60% reduction (increase) to 60% expansion (reduction), and the resource scheduling accuracy is 20%, then the resource scheduling action set generated by the scheduling action generating module 501 is: shrinking 60%, The capacity is reduced by 40%, the capacity is reduced by 20%, the capacity remains unchanged, the capacity is expanded by 20%, the capacity is expanded by 40%, and the capacity is expanded by 60%.

需要说明的是，所述调度动作生成模块501可以针对所有资源生成同一套调度动作集合，或者所述调度动作生成模块501可以针对每种资源分别生成一套调度动作集合。It should be noted that the scheduling action generating module 501 may generate the same set of scheduling actions for all resources, or the scheduling action generating module 501 may generate a set of scheduling actions for each type of resource.

通过这种方式，每个网络切片的资源管理策略中对(每个VNF的)每个资源的调度动作是该资源对应的调度动作集合中的一个调度动作，这样，最终生成的多个网络切片的资源管理策略中的调度动作可以从指数的数据级增长降为线性数据级增长。当进行资源管理的网络切片的数量较多时，这种方式的可以大大降低网络切片的资源管理策略中调度动作的种类。In this way, the scheduling action for each resource (of each VNF) in the resource management strategy of each network slice is a scheduling action in the scheduling action set corresponding to the resource, so that multiple network slices are finally generated The scheduling action in the resource management strategy can be reduced from exponential data-level growth to linear data-level growth. When the number of network slices for resource management is large, this approach can greatly reduce the types of scheduling actions in the resource management strategy of network slices.

可选的，参阅图6所示，所述调度动作生成模块501可以按照以下流程生成调度动作集合：Optionally, referring to FIG. 6, the scheduling action generating module 501 may generate a scheduling action set according to the following process:

步骤1：所述调度动作生成模块501确定每种资源的资源调度变化范围。Step 1: The scheduling action generating module 501 determines the resource scheduling change range of each resource.

其中，每种资源调度变化范围可以是网络管理人员在***中预先设定好的，这样，可以避免某些网络切片的资源需求的大幅变动会抢占过多的资源，使资源的管理调度只能在设置的范围内扩容或缩容。例如资源调度变化范围为：缩容50％～扩容50％。Among them, the change range of each resource scheduling can be preset in the system by the network manager. In this way, large changes in the resource requirements of certain network slices can be avoided, which will preempt too many resources and make resource management and scheduling only Expand or shrink the capacity within the set range. For example, the resource scheduling change range is: 50% reduction to 50% expansion.

步骤2：所述调度动作生成模块501确定每种资源的资源调度精度。其中，资源调度精度为最小的资源调度单元，即资源调度粒度或资源变化的单位。Step 2: The scheduling action generating module 501 determines the resource scheduling accuracy of each resource. Among them, the resource scheduling unit with the smallest resource scheduling accuracy is the unit of resource scheduling granularity or resource change.

可选的，所述资源调度精度可以为网络管理人员在所述***中预先设置好的，也可以是所述调度动作生成模块501确定的。示例性的，所述调度动作生成模块501可以根据***中的网络切片运行状况和网络资源使用情况，设置调配的精度。另外，资源调度精度还可以是处理器的单个内核数量或是预先设置的虚拟机数量。Optionally, the resource scheduling accuracy may be preset in the system by a network administrator, or may be determined by the scheduling action generating module 501. Exemplarily, the scheduling action generation module 501 may set the accuracy of deployment according to the network slice operating status and network resource usage in the system. In addition, the resource scheduling accuracy can also be the number of a single core of the processor or a preset number of virtual machines.

The scheduling action generating module 501 may, based on the above two pieces of information, Generate a set of scheduling actions for storage resources. The set of scheduling actions includes 11 scheduling actions, specifically, 10 resource change actions (ie, 50% reduction, 40% reduction, 30% reduction, 20% reduction, 10% reduction, and 10% expansion , 20% expansion, 30% expansion, 40% expansion, 50% expansion) and an action to keep the current resource allocation unchanged (that is, the capacity remains unchanged).

步骤4：所述调度动作生成模块501对每种资源的每个调度动作进行编号，每一个调度动作对应唯一的编号。调度动作的编号可以作为资源管理策略模型的输出，用来进行资源管理策略模型的训练。Step 4: The scheduling action generating module 501 numbers each scheduling action of each resource, and each scheduling action corresponds to a unique number. The number of the scheduling action can be used as the output of the resource management strategy model for training the resource management strategy model.

由于每个网络切片由多个VNF组成，且VNF之间并非完全独立而是相互影响，并且随着性能指标较差的VNF的数量的增加，对整个网络切片的网络性能的影响是呈非线性函数(例如指数函数)增长的。因此，在一个实现方式中，所述网络性能计算模块503可以使用非线性函数综合网络切片中所有VNF的性能进而计算网络切片的网络性能，具体包括以下步骤：Since each network slice is composed of multiple VNFs, and the VNFs are not completely independent but affect each other, and as the number of VNFs with poor performance indicators increases, the impact on the network performance of the entire network slice is nonlinear Functions (such as exponential functions) grow. Therefore, in an implementation manner, the network performance calculation module 503 may use a non-linear function to synthesize the performance of all VNFs in the network slice to calculate the network performance of the network slice, which specifically includes the following steps:

c、所述网络性能计算模块503以自然底数对不符合SLA违反率的设定条件的VNF的指标进行叠加，将计算结果乘以SLA违反率的权重得到SLA违反率减分值，并将SLA违反率的性能总分值减去SLA违反率减分值，得到车联网网络切片的SLA违反率分值。同样的，所述网络性能计算模块503以自然底数对不符合资源利用率的设定条件的VNF的指标进行叠加，将计算结果乘以资源利用率的权重得到资源利用率减分值，并将资源利用率的性能总分值减去资源利用率减分值，得到车联网网络切片的资源利用率分值。c. The network performance calculation module 503 superimposes the indicators of VNFs that do not meet the setting conditions of the SLA violation rate with a natural base, and multiplies the calculation result by the weight of the SLA violation rate to obtain the SLA violation rate deduction value, and calculates The total performance score of the violation rate is subtracted from the SLA violation rate deduction score to obtain the SLA violation rate score of the car networking network slice. Similarly, the network performance calculation module 503 superimposes the indicators of VNFs that do not meet the set conditions of resource utilization with a natural base, multiplies the calculation result by the weight of the resource utilization to obtain the resource utilization deduction value, and The total performance score of the resource utilization rate is subtracted from the resource utilization rate minus score to obtain the resource utilization score of the car networking network slice.

其中，车联网网络切片的SLA违反率分值＝S-α*e ^2S；车联网网络切片的资源利用率分值＝P-β*e ^2P。其中S为SLA违反率的性能总分值，α为SLA违反率的权重，P为资源利用率总分值，β为资源利用率的权重。 Among them, the SLA violation rate score of the Internet of Vehicles network slice=S-α*e ^2S ; the resource utilization score of the Internet of Vehicles network slice=P-β*e ^2P . Where S is the total performance score of the SLA violation rate, α is the weight of the SLA violation rate, P is the total score of resource utilization, and β is the weight of resource utilization.

d、所述网络性能计算模块503根据车联网网络切片的SLA违反率分值和资源利用率分值，以及SLA违反率分值和资源利用率的权重，计算车联网网络切片的网络性能分值。d.
