摘　　要：随着元宇宙等概念的提出,视频流应用对网络带宽和时延的要求越来越苛刻。针对传统CDN容易出现节点内设备负载不均衡造成时延过长的问题,提出了一个面向虚拟CDN的5G和MEC融合平台设计方案,并依照设计方案完成了平台的搭建。最后,通过高并发推拉流实验证明了该融合平台拓展了虚拟CDN的高并发能力。With the introduction of concepts such as metaverse,video streaming applications have become increasingly demanding in terms of network bandwidth and latency.In response to the problem of excessive latency caused by unbalance device load within nodes in traditional CDNs,a design scheme of 5G and MEC convergence platform for virtual CDN is proposed,and the platform is built according to the design scheme.Finally,the converged platform extends the high concurrency capabilities of the virtual CDN as demonstrated by high concurrency push and pull streaming experiments.
