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。MEC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,为CDN业务及相关应用的发展注入强大动力。给出了基于MEC的移动网络CDN增强架构,并进行了关键技术分析,最后结合5G初期业务发展需求,给出了典型场景的部署建议。
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 networks,inject strong power into the development of CDN services and related applications.The MEC-based mobile network CDN enhancement architecture was given and the key technologies were analyzed.Finally,combined with the initial business development requirements of 5G,the deployment recommendations of typical scenarios were given.
