基于MEC的服务节点分配方法、装置及相关服务器MEC-based service node allocation method, device and related server

技术领域technical field

本发明实施例涉及边缘计算技术领域，尤其涉及一种基于移动边缘计算(MobileEdge Computing，MEC)的服务节点分配方法、装置、云端服务器、MEC服务器以及计算机可读存储介质。Embodiments of the present invention relate to the technical field of edge computing, and in particular, to a mobile edge computing (Mobile Edge Computing, MEC)-based service node allocation method, device, cloud server, MEC server, and computer-readable storage medium.

背景技术Background technique

随着网络技术、互联网以及物联网业务的发展，人们产生了在移动网络边缘数据中心进行服务部署提供业务服务的需求，以节省移动终端与业务服务器之间的业务交互流量，降低业务交互时延，减少业务服务器的业务压力。特别是在物联网的应用场景中，边缘服务部署的需求巨大，而在移动网络边缘数据中心的接入过程中，会存在边缘接入服务器分配(又称为服务引流)的问题，需要为接入的终端应用分配对应的边缘接入服务器。With the development of network technology, Internet and Internet of Things services, there is a demand for service deployment in mobile network edge data centers to provide business services, so as to save business interaction traffic between mobile terminals and business servers and reduce business interaction delays , reduce the business pressure on the business server. Especially in the application scenario of the Internet of Things, the demand for edge service deployment is huge, and in the access process of the mobile network edge data center, there will be the problem of edge access server allocation (also known as service diversion), which needs to be The incoming terminal application allocates the corresponding edge access server.

目前，服务引流方式主要有两种，分别是域名系统(Domain Name System，DNS)解析引流方式和动态路由方式。对于DNS解析引流方式，利用应用请求的域名，通过DNS解析到需要为应用分配的边缘接入应用服务器，从而达到引流的目的；而对于动态路由方式，通过对服务器互联网协议(Internet Protocol，IP)进行动态路由，将应用请求路由到需要为应用分配的边缘接入应用服务器，从而达到引流的目的。At present, there are two main service diversion modes, namely, a Domain Name System (Domain Name System, DNS) resolution diversion mode and a dynamic routing mode. For the DNS resolution and diversion method, the domain name requested by the application is used to resolve the edge access application server that needs to be allocated for the application through DNS, so as to achieve the purpose of diversion; for the dynamic routing method, the server Internet Protocol (IP) Perform dynamic routing to route application requests to the edge access application server that needs to be allocated for the application, so as to achieve the purpose of traffic diversion.

从上述可以看出，不管是DNS解析引流方式还是动态路由方式，都受限于应用场景，比如，对于DNS解析引流方式，需要终端应用支持DNS域名访问，而在物联网场景中由于部分终端能力受限，其可能并不支持DNS域名访问，对于动态路由方式，需要依赖网络路由设备，且一般用于支持主备服务器场景，因此，现有技术中服务引流方式存在灵活性较差的问题。It can be seen from the above that whether it is the DNS resolution diversion method or the dynamic routing method, it is limited by the application scenario. For example, for the DNS resolution diversion method, the terminal application needs to support DNS domain name access. In the IoT scenario, due to some terminal capabilities Limited, it may not support DNS domain name access. For dynamic routing, it needs to rely on network routing devices, and is generally used to support active and standby server scenarios. Therefore, the service traffic diversion method in the prior art has the problem of poor flexibility.

2)切换速度受制于DNS的更新速度，会达到分钟级以上的切换时延，一些场景可能会引起业务失败；2) The switching speed is subject to the update speed of DNS, which will reach a switching delay of more than a minute, and some scenarios may cause service failure;

3)主要是根据网络性能指标的负载引流，无法支持更丰富的应用级引流策略。3) It is mainly based on load diversion based on network performance indicators, and cannot support richer application-level traffic diversion strategies.

而动态路由方式采用较少，该服务引流方式存在以下问题：However, the dynamic routing method is rarely used, and the service diversion method has the following problems:

1)需要参与网络路由计算，依赖网络路由设备；1) Need to participate in network routing calculation and rely on network routing equipment;

2)复杂性高，一般用于支持主备服务器场景，很难支持多活的服务器场景，而在基于MEC的接入场景中，边缘接入应用服务器都是多活的。2) High complexity, generally used to support active and standby server scenarios, it is difficult to support multi-active server scenarios, while in MEC-based access scenarios, edge access application servers are multi-active.

第一种方式为：所述反馈策略信息中可以包括第一网络指标阈值，相应的，MEC服务器只需要反馈网络指标信息满足所述第一网络指标阈值的服务节点的网络指标信息即可。所述第一网络指标阈值可以仅包括第一阈值，相应的，MEC服务器只需要反馈网络指标信息中网络性能度量信息满足第一阈值的服务节点的网络指标信息即可。所述第一网络指标阈值可以同时包括第一阈值和第二阈值，MEC服务器只需要反馈网络指标信息中网络性能度量信息满足第一阈值、且网络指标信息中负载信息满足第二阈值的服务节点的网络指标信息即可。The first way is: the feedback policy information may include a first network indicator threshold, and accordingly, the MEC server only needs to feed back network indicator information of a service node whose network indicator information meets the first network indicator threshold. The first network indicator threshold may only include the first threshold. Correspondingly, the MEC server only needs to feed back the network indicator information of the service node whose network performance measurement information in the network indicator information meets the first threshold. The first network indicator threshold may include both the first threshold and the second threshold, and the MEC server only needs to feed back the service nodes whose network performance measurement information in the network indicator information satisfies the first threshold and whose load information in the network indicator information satisfies the second threshold. The network indicator information can be used.

第二种方式为：MEC服务器可以综合考虑各服务节点的网络性能度量信息和负载信息，对各服务节点进行排名，反馈排名前N个服务节点的网络指标信息，所述N为大于或等于的正整数。比如，所述MEC可以设置网络性能度量信息和负载信息的权值，基于加权的方式确定各服务节点的网络的好坏，按照网络的好坏对各服务节点进行排列，将网络最好的服务节点排列在第一名，同时，将网络最坏的服务节点排列在最后一名。The second way is: the MEC server can comprehensively consider the network performance measurement information and load information of each service node, rank each service node, and feed back the network index information of the top N service nodes, where N is greater than or equal to positive integer. For example, the MEC can set the weights of the network performance measurement information and the load information, determine the network quality of each service node based on the weighting method, arrange the service nodes according to the quality of the network, and assign the best service to the network. The nodes are ranked first, and at the same time, the worst service node of the network is ranked last.

MEC服务器获取到至少一服务节点的网络指标信息之后，将所述至少一服务节点的网络指标信息反馈给所述云端服务器，相应的，所述云端服务器即可接收到所述至少一服务节点的网络指标信息。After acquiring the network indicator information of the at least one service node, the MEC server feeds back the network indicator information of the at least one service node to the cloud server. Accordingly, the cloud server can receive the network indicator information of the at least one service node. Network metrics information.

步骤103，基于所述至少一服务节点的网络指标信息，为所述终端设备选择目标服务节点；其中，所述目标服务节点为所述至少一服务节点中的服务节点。Step 103: Select a target service node for the terminal device based on the network indicator information of the at least one service node; wherein, the target service node is a service node in the at least one service node.

这里，可以根据云端服务器预先设置的引流策略，基于所述至少一服务节点的网络指标信息，为所述终端设备选择目标服务节点。Here, a target service node may be selected for the terminal device according to a traffic diversion strategy preset by the cloud server and based on the network indicator information of the at least one service node.

所述云端服务器预先设置的引流策略可以有三种，其引流策略比较灵活，支持用户颗粒度的应用级策略引流。There are three kinds of traffic diversion strategies preset by the cloud server, and the traffic diversion strategies are relatively flexible, and support user granularity application-level traffic diversion strategies.

第一种引流策略可以为：仅根据服务节点的网络指标信息，为所述终端设备选择目标服务节点。The first traffic diversion strategy may be: selecting a target service node for the terminal device only according to the network indicator information of the service node.

具体的，所述基于所述至少一服务节点的网络指标信息，为所述终端设备选择目标服务节点的步骤包括：Specifically, the step of selecting a target service node for the terminal device based on the network indicator information of the at least one service node includes:

确定所述至少一服务节点中网络指标信息最好的服务节点；determining the service node with the best network indicator information among the at least one service node;

将所述至少一服务节点中网络指标信息最好的服务节点确定为所述终端设备接入的目标服务节点。The service node with the best network indicator information among the at least one service node is determined as the target service node accessed by the terminal device.

所述云端服务器可以设置网络性能度量指标和负载信息的权值，基于加权的方式确定所述至少一服务节点中各服务节点的网络的好坏，并挑选出所述至少一服务节点中网络指标信息最好的服务节点，同时，将所述至少一服务节点中网络指标信息最好的服务节点确定为所述终端设备接入的目标服务节点。The cloud server may set the network performance metrics and the weights of the load information, determine the network quality of each service node in the at least one service node based on the weighting method, and select the network indicators in the at least one service node. The service node with the best information, and at the same time, the service node with the best network indicator information in the at least one service node is determined as the target service node accessed by the terminal device.

第二种引流策略可以为：根据服务节点的网络指标信息和终端设备的等级，为所述终端设备选择目标服务节点。The second traffic diversion strategy may be: selecting a target service node for the terminal device according to the network indicator information of the service node and the level of the terminal device.

具体的，所述基于所述至少一服务节点的网络指标信息，为所述终端设备选择目标服务节点的步骤包括：Specifically, the step of selecting a target service node for the terminal device based on the network indicator information of the at least one service node includes:

获取所述终端设备的等级；其中，所述等级用于反映所述终端设备对于应用处理的重要程度；obtaining the level of the terminal device; wherein the level is used to reflect the importance of the terminal device for application processing;

确定所述至少一服务节点中网络指标信息与所述终端设备的等级匹配的服务节点；determining a service node whose network indicator information matches the level of the terminal device in the at least one service node;

将与所述终端设备的等级匹配的服务节点确定为所述终端设备接入的目标服务节点。A service node matching the level of the terminal device is determined as the target service node accessed by the terminal device.

所述终端设备的等级用于反映所述终端设备对于应用处理的重要程度，可以为重要等级，也可以为普通等级，还可以为其他等级如超重要等级，这里不做具体限定。其中，重要等级的终端设备相对于普通等级的终端设备，其应用的处理紧急程度可以大些，需要优先处理或者快速响应处理。The level of the terminal device is used to reflect the importance of the terminal device for application processing, which may be an important level, a common level, or other levels such as a super important level, which is not specifically limited here. Among them, the terminal equipment of the important level may have a higher degree of application processing urgency than the terminal equipment of the common level, and needs to be processed with priority or rapid response processing.

所述云端服务器可以根据所述终端设备的标识信息，确定所述终端设备的等级，比如，所述云端服务器可以预先存储有终端设备的标识信息和等级的映射表，基于所述标识信息，在所述映射表中即可查询到所述终端设备的等级。The cloud server may determine the level of the terminal device according to the identification information of the terminal device. For example, the cloud server may pre-store a mapping table between the identification information and the level of the terminal device, and based on the identification information, The level of the terminal device can be queried in the mapping table.

所述云端服务器可以设置网络性能度量指标和负载信息的权值，基于加权的方式确定所述至少一服务节点中各服务节点的网络的好坏，并可以基于各服务节点的网络的好坏，对各服务节点进行排序。基于排序后的各服务节点，匹配出所述终端设备的等级相应的服务节点。The cloud server may set the network performance metrics and the weights of the load information, determine the network quality of each service node in the at least one service node based on the weighting method, and may based on the network quality of each service node, Sort each service node. Based on the sorted service nodes, a service node corresponding to the level of the terminal device is matched.

应当说明的是，所述终端设备的等级相应的服务节点可以仅包括一个，也包括多个，这里不做具体限定。比如，排序后的服务节点包括服务节点1、服务节点2、服务节点3和服务节点4，对于重要等级的终端设备，只有网络指标信息较好的服务节点1和服务节点2可以满足该终端设备的要求，也就是说，服务节点1和服务节点2与该终端设备匹配；对于普通等级的终端设备，由于其对于应用处理的性能要求不是很高，网络指标信息一般的服务节点3和服务节点4可以满足该终端设备的要求，也就是说，服务节点3和服务节点4与该终端设备匹配。It should be noted that, the service node corresponding to the level of the terminal device may include only one or a plurality of nodes, which is not specifically limited here. For example, the sorted service nodes include service node 1, service node 2, service node 3 and service node 4. For terminal devices of important levels, only service node 1 and service node 2 with better network index information can satisfy the requirements of the terminal device. , that is, service node 1 and service node 2 match the terminal device; for common-level terminal devices, since their performance requirements for application processing are not very high, service node 3 and service node with general network index information 4 can meet the requirements of the terminal device, that is, the service node 3 and the service node 4 are matched with the terminal device.

在所述终端设备的等级相应的服务节点包括多个的情况下，所述云端服务器可以将所述终端设备的等级相应的多个服务节点中的任一个服务节点确定为所述至少一服务节点中网络指标信息与所述终端设备的等级匹配的服务节点，也可以将所述终端设备的等级相应的多个服务节点中网络指标信息最好的服务节点确定为所述至少一服务节点中网络指标信息与所述终端设备的等级匹配的服务节点，这里不做具体限定。In the case where there are multiple service nodes corresponding to the level of the terminal device, the cloud server may determine any one of the multiple service nodes corresponding to the level of the terminal device as the at least one service node The service node whose network indicator information matches the level of the terminal device may also determine the service node with the best network indicator information among the multiple service nodes corresponding to the level of the terminal device as the network in the at least one service node. The service node whose index information matches the level of the terminal device is not specifically limited here.

当然，所述云端服务器也可以将所述终端设备的等级相应的多个服务节点都确定为所述终端设备接入的目标服务节点，相应的，将各所述目标服务节点的访问标识都发送给终端设备，让终端设备基于各所述目标服务节点的访问标识中的任一访问标识接入目标服务节点。Of course, the cloud server may also determine multiple service nodes corresponding to the level of the terminal device as the target service node accessed by the terminal device, and accordingly, send the access identifiers of each target service node. For the terminal device, let the terminal device access the target service node based on any one of the access identifiers of the target service nodes.

第三种引流策略可以为：根据服务节点的网络指标信息和终端设备的特征信息，为所述终端设备选择目标服务节点。The third traffic diversion strategy may be: selecting a target service node for the terminal device according to the network indicator information of the service node and the characteristic information of the terminal device.

具体的，所述基于所述至少一服务节点的网络指标信息，为所述终端设备选择目标服务节点的步骤包括：Specifically, the step of selecting a target service node for the terminal device based on the network indicator information of the at least one service node includes:

For example, for a video playback application, the terminal device's preference for video definition is 1080P, and the cloud server counts the terminal device's historical setting data for the video playback application to determine the The preference setting of the playback application, the preference setting is the feature information of the terminal device for the video playback application, and the feature information may include the video definition preference setting 1080P, that is, the cloud server is based on the feature information in the video clarity The preference setting of the degree is 1080P, and it can be determined that the terminal device has higher performance requirements for the network.

进一步的，所述云端服务器可以基于所述特征信息，确定第二网络指标阈值，在所述至少一服务节点中存在服务节点的网络指标信息大于所述第二网络指标阈值时，则确定该网络指标信息与所述特征信息匹配，相应的，将与所述特征信息匹配的网络指标信息对应的服务节点确定为目标服务节点。Further, the cloud server may determine a second network indicator threshold based on the feature information, and when the network indicator information of a service node in the at least one service node is greater than the second network indicator threshold, determine the network indicator.
