摘　　要：多接入边缘计算(Multi-access Edge Computing,MEC)通过将计算存储能力与业务服务能力向网络边缘迁移,使应用、服务和内容可以实现本地化部署,可以解决传统内容分发网络(Content Delivery Network,CDN)中边缘节点无法下沉到移动网络中的痛点问题。但是,CDN节点下沉到网络边缘后,CDN需要网络和终端辅助业务识别用户位置,实现边缘业务分流。提出了一种基于MEC的边缘CDN业务调度方案,测试结果表明,所提方案可以极大地降低首包时延并提高下载速率,明显改善用户的业务体验。Multi-access edge computing(MEC)enables applications,services and content to be deployed locally by migrating computing storage and business service capabilities to the edge of network.MEC can solve the problem that traditional content delivery network(CDN)nodes cannot sink into mobile network.However,after the CDN node sinks to the edge of the network,the CDN needs the network and terminal to assist the service to identify the user′s location and realize the traffic offload.This paper proposes an edge CDN service scheduling scheme based on MEC.Test results show that the proposed scheme can greatly reduce the first packet delay and increase the download rate,and significantly improve the user′s business experience.
