以下结合附图，详细说明本申请各实施例提供的技术方案。The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
图1a为本申请示例性实施例提供的一种网络***的结构示意图。如图1a所示，该网络***100包括：中心管控设备101和至少一个边缘云节点102；至少一个边缘云节 点102均与中心管控设备101网络连接。Fig. 1a is a schematic structural diagram of a network system provided by an exemplary embodiment of this application. As shown in Fig. 1a, the network system 100 includes: a central control device 101 and at least one edge cloud node 102; at least one edge cloud node 102 is connected to the central control device 101 in a network.
本实施例的网络***100是基于云计算技术和边缘计算的能力，构筑在边缘基础设施之上的云计算平台，是一种边缘位置的具备计算、网络、存储、安全等能力的云平台。The network system 100 in this embodiment is a cloud computing platform built on edge infrastructure based on cloud computing technology and edge computing capabilities, and is a cloud platform with computing, network, storage, and security capabilities at the edge.
与中心云或者传统的云计算平台相对应，本实施例的网络***100可以视为一种边缘云网络***。边缘云是个相对概念，边缘云是指相对靠近终端的云计算平台，或者说，与中心云或者传统的云计算平台相区别，中心云或者传统的云计算平台可以包括资源规模化且位置集中的数据中心，而边缘云节点覆盖的网络范围更广泛，也因此具备距离终端更近的特性，单个边缘云节点的资源规模较小，但是边缘云节点的数量多，多个边缘云节点构成了本实施例中边缘云的组成部分。本实施例的终端是指云计算服务的需求端，例如可以是互联网中的终端或者用户端，或者物联网中的终端或用户端。边缘云网络是基于中心云或者传统的云计算***与终端之间的基础设施构建的网络。其中，网络***100包括至少一个边缘云节点102，每个边缘云节点102包括一系列的边缘基础设施，这些边缘基础设施包括但不限于：分布式数据中心(DC)、无线机房或集群，运营商的通信网络、核心网设备、基站、边缘网关、家庭网关、计算设备或存储设备等边缘设备及对应的网络环境等等。在此说明，不同边缘云节点102的位置、能力以及包含的基础设施可以相同，也可以不相同。Corresponding to a central cloud or a traditional cloud computing platform, the network system 100 of this embodiment can be regarded as an edge cloud network system. Edge cloud is a relative concept. Edge cloud refers to a cloud computing platform that is relatively close to the terminal. In other words, it is different from central cloud or traditional cloud computing platform. Central cloud or traditional cloud computing platform can include large-scale resources and centralized locations. Data centers, and edge cloud nodes cover a wider network range, and therefore have the characteristics of being closer to the terminal. The resource scale of a single edge cloud node is small, but the number of edge cloud nodes is large, and multiple edge cloud nodes constitute the original Part of the edge cloud in the embodiment. The terminal in this embodiment refers to the demand side of cloud computing services, for example, it may be a terminal or a user side in the Internet, or a terminal or a user side in the Internet of Things. The edge cloud network is a network based on the infrastructure between the central cloud or the traditional cloud computing system and the terminal. Wherein, the network system 100 includes at least one edge cloud node 102, and each edge cloud node 102 includes a series of edge infrastructures. These edge infrastructures include, but are not limited to: distributed data centers (DC), wireless computer rooms or clusters, operations Communication network, core network equipment, base station, edge gateway, home gateway, computing equipment or storage equipment and other edge equipment and corresponding network environment. It is explained here that the locations, capabilities, and included infrastructure of different edge cloud nodes 102 may be the same or different.
其中，本实施例的网络***100与中心云或传统的云计算平台等中心网络、终端结合可形成“云边端三体协同”的网络架构，在该网络架构中，可以将网络转发、存储、计算以及智能化数据分析等任务放在网络***100中的各边缘云节点102中处理，由于各边缘云节点102更靠近终端，因此可以降低响应时延，减轻中心云或传统的云计算平台的压力，降低带宽成本。Among them, the network system 100 of this embodiment is combined with a central cloud or a traditional cloud computing platform and other central networks and terminals to form a "cloud edge-end three-body coordination" network architecture. In this network architecture, the network can be forwarded and stored. Tasks such as computing and intelligent data analysis are processed in each edge cloud node 102 in the network system 100. Since each edge cloud node 102 is closer to the terminal, the response delay can be reduced and the central cloud or traditional cloud computing platform can be reduced. Pressure to reduce bandwidth costs.
如何合理地调度多个边缘云节点资源，以及如何管控好多个边缘云节点以正确和稳定的逻辑进行云计算服务，是一个重要的挑战。在本实施例的网络***100中，部署有中心管控设备101，中心管控设备101以边缘云节点102为管控对象，在资源调度，镜像管理，实例管控，运维，网络，安全等各方面对网络***100中的至少一个边缘云节点102进行统一管控，从而将云计算服务放到各边缘云节点102中处理。在部署实施上，中心管控设备101可以部署在一个或多个云计算数据中心中，或者，可以部署在一个或多个传统数据中心中，中心管控设备101也可以和其管控的至少一个边缘云节点共同构成边缘云网络，本实施例对此不做限定。How to reasonably schedule the resources of multiple edge cloud nodes and how to manage and control multiple edge cloud nodes to perform cloud computing services with correct and stable logic is an important challenge. In the network system 100 of this embodiment, a central management and control device 101 is deployed. The central management and control device 101 uses the edge cloud node 102 as the management and control object for resource scheduling, image management, instance management and control, operation and maintenance, network, security, etc. At least one edge cloud node 102 in the network system 100 is uniformly managed and controlled, so that cloud computing services are placed in each edge cloud node 102 for processing.

Based on this, after determining the target edge cloud node, the resource scheduling management control module 11a may determine the scheduled resource information in the target edge cloud node according to the resource selection parameters. The resource information here may include: resource type, resource quantity, and/or performance requirements for resource devices, so that the edge management and control device 103 can control the corresponding resource device in the target edge cloud node to allocate or reserve resources accordingly. For example, resource types may include, but are not limited to: computing resources such as CPU and GPU, storage resources such as memory and hard disk, and resource types such as bandwidth resources. Taking CPU resources as an example, the number of resources can be 12 CPUs, 24 CPUs, etc., taking memory resources as an example, the number of resources can be 16G memory, 32G memory, etc.; taking bandwidth resources as an example, the number of resources can be 1M bandwidth, 10M Bandwidth etc.
可选地，资源调度管控模块11a还可以具有算力编排的功能，算力编排是面向相对复杂一些的应用场景，将多个云计算服务绑定在一起作为最小的资源需求单元，这样，在资源调度过程中，可将绑定在一起的多个云计算服务作为整体，为它们选择同一个或几个边缘云节点，由同一个或几个边缘云节点为它们共同提供资源。算力编排本质上完善了资源调度的多样性，增加了资源调度的灵活性，但未对资源调度的整体流程产生影响。Optionally, the resource scheduling management and control module 11a may also have the function of computing power orchestration. The computing power orchestration is oriented to relatively complex application scenarios and binds multiple cloud computing services together as the smallest resource requirement unit. In the resource scheduling process, multiple cloud computing services that are bound together can be selected as a whole, and the same or several edge cloud nodes can be selected for them, and the same or several edge cloud nodes can provide resources for them together. Computing power orchestration essentially improves the diversity of resource scheduling and increases the flexibility of resource scheduling, but it does not affect the overall process of resource scheduling.
其中，镜像管控模块12a主要实现中心管控设备101的镜像管理和分发能力，用于获取云计算服务所需的镜像，将镜像提供给边缘管控设备103，由边缘管控设备103将镜像提供给目标边缘云节点中相应资源设备，以供相应资源设备利用分配或预留的资源提供云计算服务。Among them, the image management and control module 12a mainly implements the image management and distribution capabilities of the central management and control device 101, and is used to obtain the image required for cloud computing services, and provide the image to the edge management and control device 103, and the edge management and control device 103 provides the image to the target edge The corresponding resource equipment in the cloud node allows the corresponding resource equipment to use the allocated or reserved resources to provide cloud computing services.

The image demander or the cloud computing service demander can choose to use the image in the image library. For example, a mirror configuration interface can be provided with a drop-down menu on the interface. The drop-down menu includes many mirrors for users to choose. The mirror demander or the cloud computing service demander can choose the mirror they use. Based on this, the image management and control module 12a can obtain the image required by the cloud computing service from the image library, and then provide the image to the edge management and control device 103, and open the use right of the image to the image demander or the cloud computing service demander.
可选地，也可以面向用户提供一种镜像的规则和规范，让用户自己制作或生成云计算服务所需的镜像，该镜像需要符合边缘云环境的相关要求。在制作或生成云计算服务 所需的镜像之后，用户可以将制作或生成的镜像提交给镜像管控模块12a。基于此，镜像管控模块12a可以接收云计算服务需求方提交的镜像，对该镜像进行合法性校验；若镜像通过合法性校验，将镜像添加到镜像库中，并将镜像提供给边缘管控设备103。这里的合法性校验包括验证镜像的格式、生成规则、规范等是否符合边缘云环境的相关规定。Optionally, a mirroring rule and specification can also be provided to users, allowing users to make or generate the mirroring required by cloud computing services by themselves, and the mirroring needs to meet the relevant requirements of the edge cloud environment. After making or generating the image required by the cloud computing service, the user can submit the made or generated image to the image management and control module 12a. Based on this, the image management and control module 12a can receive the image submitted by the cloud computing service demander, and verify the legality of the image; if the image passes the legality check, the image is added to the image library, and the image is provided to edge management and control Equipment 103. The legality verification here includes verifying whether the image format, generation rules, specifications, etc. comply with the relevant regulations of the edge cloud environment.
与中心管控设备101相类似，边缘管控设备103也可以是一台逻辑设备，其具有的能力可以部署一台物理机(例如边缘云节点中的资源设备或专有设备)或虚拟机上实现，也可以分散性地部署在多台物理机(例如边缘云节点中的资源设备或专有设备)或虚拟机上。当然，边缘管控设备也可以是一台或多台具有相应能力的物理设备。凡是具有相应能力的设备结构均适用于本申请实施例，下面列举一种边缘管控设备的实现结构，该实现结构仅为示例，并不限于此。Similar to the central management and control device 101, the edge management and control device 103 can also be a logical device, which has the ability to deploy a physical machine (for example, a resource device or a proprietary device in an edge cloud node) or a virtual machine.

其中，资源调度服务模块11b，主要实现与中心管控设备的资源调度能力相对应的能力，用于获取资源调度管控模块11a提供的资源信息，根据该资源信息控制目标边缘云节点中相应资源设备进行资源分配或预留。例如，资源调度服务模块11b可以接收资源调度管控模块11a发送的资源信息，或者可以到资源调度管控模块11a指定的存储位置下载该资源信息。Among them, the resource scheduling service module 11b mainly realizes the ability corresponding to the resource scheduling ability of the central management and control equipment, and is used to obtain the resource information provided by the resource scheduling management and control module 11a, and control the corresponding resource equipment in the target edge cloud node according to the resource information. Resource allocation or reservation. For example, the resource scheduling service module 11b can receive the resource information sent by the resource scheduling management and control module 11a, or can download the resource information from the storage location designated by the resource scheduling management and control module 11a.
其中，根据资源信息的不同，负责进行资源分配或预留的资源设备也会有所不同，负责进行资源预留的资源设备可以是一台，也可能是多台。例如，若该资源信息包括CPU资源信息、存储资源信息和带宽资源信息，资源调度服务模块11b可以根据CPU资源信息、存储资源信息和带宽资源信息控制一台具有上网功能的计算设备进行CPU资源、存储资源和带宽资源的分配或预留；除此之外，资源调度服务模块11b也可以根据CPU资源信息和带宽资源控制一台计算设备进行CPU资源和带宽资源的分配或预留，并根据存储资源信息控制一台存储设备进行存储资源的分配或预留。Among them, according to different resource information, the resource equipment responsible for resource allocation or reservation will also be different, and the resource equipment responsible for resource reservation may be one or multiple. For example, if the resource information includes CPU resource information, storage resource information, and bandwidth resource information, the resource scheduling service module 11b can control a computing device with Internet access function to perform CPU resources, based on the CPU resource information, storage resource information, and bandwidth resource information. The allocation or reservation of storage resources and bandwidth resources; in addition, the resource scheduling service module 11b can also control a computing device to allocate or reserve CPU resources and bandwidth resources according to CPU resource information and bandwidth resources, and according to storage Resource information controls a storage device to allocate or reserve storage resources.
镜像服务模块12b，主要实现与中心管控设备的镜像管理和分发能力相对应的能力，用于获取镜像管控模块12a提供的镜像，将所获取的镜像提供给目标边缘云节点中进行资源分配或预留的相应资源设备，供相应资源设备利用分配或预留的资源提供相应云计算服务。可选地，镜像服务模块12b可以接收镜像管控模块12a发送的镜像，或者可以到镜像管控模块12a指定的存储位置下载镜像。The image service module 12b mainly implements the capabilities corresponding to the image management and distribution capabilities of the central management and control device, and is used to obtain the image provided by the image management and control module 12a, and provide the obtained image to the target edge cloud node for resource allocation or pre-processing. The corresponding resource equipment reserved for the corresponding resource equipment to use the allocated or reserved resources to provide corresponding cloud computing services. Optionally, the mirroring service module 12b can receive the mirroring sent by the mirroring management and control module 12a, or can download the mirroring to a storage location designated by the mirroring management and control module 12a.
可选地，镜像服务模块12b拿到镜像之后，可以将镜像存储在指定存储空间中，然后通知分配或预留资源的资源设备来读取镜像。资源设备在边缘管控设备的控制下可通过硬件或软件支持的能力以虚拟化的形式为实例提供计算、网络和存储等资源，对应的镜像会以***盘的形式挂载到对应的实例。在实例创建完成后，对实例尝试启动，在成功启动对应的实例后，就可以利用这些资源设备的能力提供云计算服务。其中，资源设备在边缘管控设备的控制下为实例提供计算、网络和存储等资源包括：边缘管控设备根据中心管控设备提供的资源模板从目标边缘节云点内分配或预留的资源中申请相关的计算资源、存储资源和/或网络资源；通过调用目标边缘云节点内的计算、存储、网络等执行器进行相关资源的创建动作。其中，资源的创建动作包括：处理存储相关的资源，根据镜像的配置信息及镜像内容创建实例的***盘，根据资源模板创建对应的数据盘；创建实例依赖的网络资源，例如IP地址或虚拟交换机等；以及根据结合资源模板创建计算资源。Optionally, after the image service module 12b obtains the image, it can store the image in a designated storage space, and then notify the resource device that allocates or reserves resources to read the image. Under the control of the edge management and control device, the resource device can provide computing, network, and storage resources for instances in the form of virtualization through the capabilities supported by hardware or software, and the corresponding image will be mounted to the corresponding instance in the form of a system disk. After the instance is created, try to start the instance. After the corresponding instance is successfully started, the capabilities of these resource devices can be used to provide cloud computing services. Among them, the resource device provides computing, network, and storage resources for the instance under the control of the edge management and control device, including: the edge management and control device applies for related resources from the resources allocated or reserved in the target edge node cloud according to the resource template provided by the central management and control device The computing resources, storage resources and/or network resources of the target edge cloud node are used to create related resources by calling the calculation, storage, network and other executors in the target edge cloud node. Among them, resource creation actions include: processing storage-related resources, creating a system disk for an instance based on the configuration information and content of the image, creating a corresponding data disk based on the resource template; creating network resources that the instance depends on, such as IP addresses or virtual switches And so on; and create computing resources based on the combined resource template.
在本实施例中，镜像服务模块12b除了负责从镜像管控模块12a接收或下载镜像，并具备镜像配置和存储能力之外，还可以对边缘云节点内的镜像进行管控，支持镜像适配不同硬件和***等。In this embodiment, the mirroring service module 12b is responsible for receiving or downloading mirroring from the mirroring management and control module 12a, and has mirroring configuration and storage capabilities, and can also manage and control the mirroring in the edge cloud node, and support mirroring to adapt to different hardware And systems etc.
值得说明的是，中心管控设备101的资源调度能力并不限于上面提到的一些，凡是与边缘云节点中被调度资源相关的一些管控操作也可以属于中心管控设备101的资源调度范畴之内。下面将从资源调度管控模块11a和/或资源调度服务模块11b的角度，对资源调度范畴内的其它操作进行示例性说明。It is worth noting that the resource scheduling capabilities of the central management and control device 101 are not limited to those mentioned above, and some management and control operations related to the scheduled resources in the edge cloud node may also belong to the resource scheduling scope of the central management and control device 101. The following will exemplify other operations in the resource scheduling category from the perspective of the resource scheduling management and control module 11a and/or the resource scheduling service module 11b.
在一些可选实施例中，资源调度服务模块11b在根据资源信息控制目标边缘云节点中相应资源设备进行资源分配或预留之后，还可以监控相应资源设备的资源分配或预留情况，在资源分配或预留成功的情况下，通知资源调度管控模块11a记录相应的资源分配或预留成功信息；或者，在资源分配或预留失败的情况下，将资源分配或预留失败原因上报给资源调度管控模块11a，以供资源调度管控模块11a重新确定新的目标边缘云节点。In some optional embodiments, the resource scheduling service module 11b may also monitor the resource allocation or reservation status of the corresponding resource device after controlling the resource allocation or reservation of the corresponding resource device in the target edge cloud node according to the resource information. In the case of successful allocation or reservation, notify the resource scheduling management and control module 11a to record the corresponding resource allocation or reservation success information; or, in the case of resource allocation or reservation failure, report the resource allocation or reservation failure reason to the resource The scheduling management module 11a is used for the resource scheduling management module 11a to re-determine a new target edge cloud node.
相应地，资源调度管控模块11a还可以接收资源调度服务模块11b发送的资源分配或预留成功的通知，记录相应资源分配或预留成功信息。可选地，资源调度管控模块11a可以将资源分配或预留成功信息记录到资源信息库中。或者，资源调度管控模块11a还可以接收资源调度服务模块11b上报的资源分配或预留失败原因，根据该失败原因重新确定新的目标边缘云节点。Correspondingly, the resource scheduling management and control module 11a may also receive a notification of the success of resource allocation or reservation sent by the resource scheduling service module 11b, and record the corresponding resource allocation or reservation success information. Optionally, the resource scheduling management and control module 11a may record the resource allocation or reservation success information in the resource information database. Alternatively, the resource scheduling management and control module 11a may also receive the resource allocation or reservation failure reason reported by the resource scheduling service module 11b, and re-determine a new target edge cloud node based on the failure reason.
在另一些可选实施例中，在云计算服务结束后，或者需要进行边缘云节点切换的情况下，会涉及到资源释放操作。该资源释放操作可由资源调度管控模块11a主动发起，也可以由资源调度服务模块11b申请。例如，在云计算服务结束后，资源调度管控模块11a可以向资源调度服务模块11b发送资源释放通知，以供资源调度服务模块11b通知目标边缘云节点中相应资源设备进行资源释放。又例如，若资源调度服务模块11b判断出需要进行资源释放操作时，可以向资源调度管控模块11a发送资源释放申请，该资源释放申请包括资源释放原因，例如云计算服务结束；资源调度管控模块11a接收资源释放申请，可以对资源释放申请中的资源释放原因进行审核，并在审核通过的情况下，向资源调度服务模块11b发送资源释放通知，这意味着允许目标边缘云节点进行资源释放。对资源调度服务模块11b而言，可接收资源释放通知，然后根据资源释放通知，通知目标边缘云节点中相应资源设备进行资源释放。In other optional embodiments, after the end of the cloud computing service, or in the case of edge cloud node switching, a resource release operation may be involved. The resource release operation can be actively initiated by the resource scheduling management control module 11a, or can be applied for by the resource scheduling service module 11b. For example, after the cloud computing service ends, the resource scheduling management control module 11a may send a resource release notification to the resource scheduling service module 11b, so that the resource scheduling service module 11b can notify the corresponding resource device in the target edge cloud node to release the resource. For another example, if the resource scheduling service module 11b determines that a resource release operation is needed, it can send a resource release request to the resource scheduling management and control module 11a. The resource release request includes the reason for the resource release, such as the end of the cloud computing service; the resource scheduling management and control module 11a Upon receiving the resource release application, the resource release reason in the resource release application can be reviewed, and if the review is passed, a resource release notification is sent to the resource scheduling service module 11b, which means that the target edge cloud node is allowed to perform resource release. For the resource scheduling service module 11b, it can receive a resource release notification, and then according to the resource release notification, notify the corresponding resource device in the target edge cloud node to release the resource.
在又一些可选实施例中，当前使用的目标边缘云节点有可能故障，或者出现资源不足等问题，为了保证云计算服务的正常进行，可能需要切换边缘云节点。边缘云节点的切换操作可以由资源调度管控模块11a发起，也可以由资源调度服务模块11b发起。In still other alternative embodiments, the currently used target edge cloud node may be faulty, or there may be problems such as insufficient resources. In order to ensure the normal operation of the cloud computing service, it may be necessary to switch the edge cloud node. The switching operation of the edge cloud node may be initiated by the resource scheduling management control module 11a, or may be initiated by the resource scheduling service module 11b.
若资源调度管控模块11a发起边缘云节点切换操作，则可以重新启动目标边缘云节点选择流程，为用户选择新的目标边缘云节点并确定新的目标边缘云节点中被调度的资源信息，将被调度的资源信息下发给新的目标边缘云节点中的资源调度服务模块11b，由资源调度服务模块11b根据该资源信息控制新的目标边缘云节点中相应资源设备进行资源分配或预留。If the resource scheduling management and control module 11a initiates an edge cloud node switching operation, it can restart the target edge cloud node selection process to select a new target edge cloud node for the user and determine the scheduled resource information in the new target edge cloud node. The scheduled resource information is delivered to the resource scheduling service module 11b in the new target edge cloud node, and the resource scheduling service module 11b controls the corresponding resource device in the new target edge cloud node to allocate or reserve resources according to the resource information.
若资源调度服务模块11b发起边缘云节点切换操作，可以向资源调度管控模块11a发送边缘云节点切换请求。资源调度管控模块11a接收边缘云节点切换请求，根据边缘云节点切换请求，重新启动目标边缘云节点选择流程，选择新的目标边缘云节点并确定新的目标边缘云节点中被调度的资源信息，将被调度的资源信息下发给新的目标边缘云节点中的资源调度服务模块11b，由资源调度服务模块11b根据该资源信息控制新的目标边缘云节点中相应资源设备进行资源分配或预留。If the resource scheduling service module 11b initiates an edge cloud node switching operation, it can send an edge cloud node switching request to the resource scheduling management and control module 11a. The resource scheduling management and control module 11a receives the edge cloud node switching request, restarts the target edge cloud node selection process according to the edge cloud node switching request, selects a new target edge cloud node, and determines the scheduled resource information in the new target edge cloud node, The scheduled resource information is delivered to the resource scheduling service module 11b in the new target edge cloud node, and the resource scheduling service module 11b controls the corresponding resource device in the new target edge cloud node to allocate or reserve resources according to the resource information. .
进一步，待新的目标边缘云节点中的资源分配或预留完成之后，资源调度管控模块11a可以向原目标边缘云节点中的资源调度服务模块11b发送资源释放通知，以通知原目标边缘云节点中释放当前资源。Further, after the resource allocation or reservation in the new target edge cloud node is completed, the resource scheduling management and control module 11a may send a resource release notification to the resource scheduling service module 11b in the original target edge cloud node to notify the original target edge cloud node Release current resources.
无论是资源调度管控模块11a发起边缘云节点切换操作，还是资源调度服务模块11b发起边缘云节点切换操作，镜像管控模块12a会将云计算服务所需的镜像提供给新的目标边缘云节点中的镜像服务模块12b，由镜像服务模块12b将镜像提供给新的目标边缘云节点相应资源设备，以供相应资源设备利用分配或预留的资源提供云计算服务。Whether the resource scheduling management and control module 11a initiates the edge cloud node switching operation or the resource scheduling service module 11b initiates the edge cloud node switching operation, the image management and control module 12a will provide the image required by the cloud computing service to the new target edge cloud node. In the image service module 12b, the image service module 12b provides the image to the corresponding resource device of the new target edge cloud node, so that the corresponding resource device can use the allocated or reserved resources to provide cloud computing services.
可选地，除了切换边缘云节点之外，也有可能是目标边缘云节点中当前资源设备故障或出现问题，此时，可以将云计算服务对应的实例从一个资源设备迁移到当前边缘云节点中的另一个资源设备上。在边缘云节点内部的迁移过程，可以由资源调度管控模块11a发起，也可以由资源调度服务模块11b发起。Optionally, in addition to switching the edge cloud node, it is also possible that the current resource device in the target edge cloud node is faulty or has a problem. At this time, the instance corresponding to the cloud computing service can be migrated from a resource device to the current edge cloud node On another resource device. The migration process within the edge cloud node may be initiated by the resource scheduling management and control module 11a, or may be initiated by the resource scheduling service module 11b.
在又一些可选实施例中，随着云计算服务的不断部署，目标边缘云节点中的资源有可能不足；当然，随着云计算服务的逐渐完成(完成后会释放资源)，目标边缘云节点中的资源也有可能会出现闲置。为了提高边缘云节点中的资源利用率，资源调度服务模块11b还可以监控目标边缘云节点中的资源使用率，在资源使用率超过设定使用率上限值的情况下，向资源调度管控模块11a发送资源增加申请，或者，在资源使用率地域设定使用率下限值的情况下，向资源调度管控模块11a发送资源减少申请。本实施例中，并不限定资源使用率上限值和资源使用率下限值的取值，可根据应用需求灵活设置。In other alternative embodiments, as cloud computing services are continuously deployed, resources in the target edge cloud node may be insufficient; of course, as the cloud computing service is gradually completed (resources will be released after completion), the target edge cloud The resources in the node may also be idle. In order to improve the resource utilization rate in the edge cloud node, the resource scheduling service module 11b can also monitor the resource utilization rate in the target edge cloud node, and when the resource utilization rate exceeds the upper limit of the set utilization rate, the resource scheduling management control module 11a sends an application for resource increase, or, in the case that the lower limit of the utilization rate is set in the resource utilization rate region, sends a resource reduction request to the resource scheduling management and control module 11a. In this embodiment, the upper limit value of the resource usage rate and the lower limit value of the resource usage rate are not limited, and can be flexibly set according to application requirements.
进一步，为了降低资源增加或减少的合理性，避免过度频繁的申请资源增加或减少，还可以设定一时间阈值。则，资源调度服务模块11b可以监控目标边缘云节点中的资源使用率，若资源使用率超过设定使用率上限值，且超过设定使用率上限值的时间达到设定的时间阈值，这说明目标边缘云节点的资源使用率长时间过高，资源相对紧缺，故可以向资源调度管控模块11a发送资源增加申请。同理，资源调度服务模块11b可以监控目标边缘云节点中的资源使用率，若资源使用率低于设定使用率下限值，且低于设定使用率下限值的时间达到设定的时间阈值，这说明目标边缘云节点的资源使用率长时间闲置，资源相对充裕，故可以向资源调度管控模块11a发送资源减少申请。Further, in order to reduce the rationality of resource increase or decrease, and to avoid excessively frequent application for resource increase or decrease, a time threshold can also be set. Then, the resource scheduling service module 11b can monitor the resource usage rate in the target edge cloud node. If the resource usage rate exceeds the set usage rate upper limit, and the time exceeding the set usage rate upper limit reaches the set time threshold, This indicates that the resource usage rate of the target edge cloud node is too high for a long time, and the resources are relatively short, so a resource increase request can be sent to the resource scheduling management control module 11a. Similarly, the resource scheduling service module 11b can monitor the resource usage rate in the target edge cloud node. If the resource usage rate is lower than the set usage rate lower limit, and the time below the set usage rate lower limit reaches the set Time threshold, which indicates that the resource usage rate of the target edge cloud node is idle for a long time, and the resources are relatively abundant, so a resource reduction request can be sent to the resource scheduling management and control module 11a.
对资源调度管控模块11a来说，还可以在接收到资源增加申请时，判断目标边缘云节点中是否还有空余物理机，并在有空余物理机的情况下，将空余物理机作为可用资源添加到目标边缘云节点的资源列表中；或者，还可以在接收到资源减少申请时，判断目标边缘云节点是否适合减少资源，并在适合减少资源的情况下，将目标边缘云节点中的空余物理机从目标边缘云节点的资源列表中删除。For the resource scheduling management and control module 11a, when a resource increase request is received, it can also determine whether there are spare physical machines in the target edge cloud node, and if there are spare physical machines, add the spare physical machines as available resources. To the resource list of the target edge cloud node; or, when receiving a resource reduction request, it can also determine whether the target edge cloud node is suitable for reducing resources, and if it is suitable for reducing resources, remove the spare physical The machine is deleted from the resource list of the target edge cloud node.
进一步，分别如图1c和图1d所示，中心管控设备101还包括：运维管控模块13a；相应地，边缘管控设备103还包括：运维服务模块13b。Further, as shown in FIG. 1c and FIG. 1d respectively, the central management and control device 101 further includes: an operation and maintenance management and control module 13a; correspondingly, the edge management and control device 103 further includes: an operation and maintenance service module 13b.

基于运维服务模块13b和运维管控模块13a，中心管控设备101可以统一监控各个边缘云节点的整体状态，便于更加合理的对边缘云节点进行资源调度。Based on the operation and maintenance service module 13b and the operation and maintenance management and control module 13a, the central management and control device 101 can uniformly monitor the overall status of each edge cloud node, which facilitates more reasonable resource scheduling of the edge cloud nodes.
针对边缘云节点，中心管控设备101通过资源调度管控模块11a、镜像管控模块12a和运维管控模块13a等对边缘云节点进行资源调度、镜像、实例和/或运维等多方面的管控。中心管控设备的各功能模块可以集中部署在一台物理机或虚拟机上，也可以分散部署在多台物理机或虚拟机上。For edge cloud nodes, the central management and control device 101 performs resource scheduling, mirroring, instance, and/or operation and maintenance on edge cloud nodes through resource scheduling management and control module 11a, mirroring management and control module 12a, and operation and maintenance management and control module 13a. The functional modules of the central management and control equipment can be centrally deployed on one physical machine or virtual machine, or distributed on multiple physical machines or virtual machines.
针对中心管控设备，边缘管控设备103通过资源调度服务模块11b、镜像服务模块12b和运维服务模块13b等配合中心管控设备在资源调度、镜像、实例和/或运维等多方面的管控。边缘管控设备的各功能模块可以集中部署在一台物理机或虚拟机上，也可以分散部署在多台物理机或虚拟机上。Regarding the central management and control equipment, the edge management and control equipment 103 cooperates with the central management and control equipment in resource scheduling, mirroring, instance, and/or operation and maintenance through resource scheduling service module 11b, mirroring service module 12b, and operation and maintenance service module 13b.
