【Abstract】 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 MEC-vCDN module and 5G network module are built, and the functions of each module in the scheme are tested.更多还原
