Description

Method, system, equipment and medium for scheduling edge vCDN scene resources Technical Field The present invention relates to the field of content distribution networks, and in particular, to a method, a system, an apparatus, and a medium for scheduling scene resources by using an edge vCDN. Background CDNs (Content Delivery Network, content delivery networks) are a group of servers distributed in different geographical locations, the purpose of which is to deliver internet content to users more efficiently. And vCDN (Vitural Content Deliver Network, virtualized content delivery network) is a virtualized CDN software application that can run CDN workloads on a proprietary, bare metal, virtualized, or container-based infrastructure. The vCDN is deployed on the edge computing node to be a novel form of CDN service, and although the performance utilization rate and service flexibility of the server are improved compared with the traditional CDN, a physical server in an edge computing scene has the inherent characteristics of light weight and shortage of physical resources, after the vCDN is deployed on the edge node, when the vCDN service load is increased, the situation that the resource occupancy rate of the edge node is too high easily occurs, so that the operation of vCDN self content distribution service is blocked, and the normal development of other public cloud services running on the node at the same time can be influenced. The prior edge vCDN node resource shortage related solution is based on the traditional CDN node design, and is subject to the condition that the single drainage mode for transferring the flow to other nodes is adopted in the presence of overhigh load, so that the service hit rate and usability of CDN are reduced due to the fact that the single drainage mode is easily interfered by factors such as network, distance and the like, and the real-time performance of monitoring and focusing on upper-layer indexes such as user service quality, video service quality and the like is poor, and when vCDN service is unstable, the problem root is difficult to quickly early warn and accurately find.
