摘　　要：MEC被广泛应用于CDN边缘下沉解决方案中,利用MEC实现CDN边缘部署,提升CDN应用的服务质量。首先,总结并分析了CDN技术演进历程及未来发展趋势;然后,提出了5G网络场景下MEC与CDN融合体系架构设计方案,所提方案具有MEC与CDN管理层解耦的特点,支持MEC-vCDN集群与传统CDN集群兼容并存;最后,搭建了MEC-vCDN模块及5G网络模块,测试了方案中各模块的功能。MEC is widely used in CDN edge sinking solutions to achieve CDN edge deployment and improve the service quality of CDN applications.Firstly,the evolution process and future development trends of CDN technology are summarized and analyzed.Then,a design scheme for the converged system architecture of MEC and CDN in 5G network scenarios is proposed,which has the characteristics of decoupling MEC and CDN management layers and supports the compatibility and coexistence of MEC-vCDN clusters and traditional CDN clusters.Finally,the MECvCDN module and 5G network module are built,and the functions of each module in the scheme are tested.
