摘要：

摘 要：基于现有移动CDN和核心网云化研究基础，探讨在云化的EPC资源上部署CDN节点的实现方法。首先分析了移动CDN节点在LTE核心网的部署方案以及核心网云化方案，进而探讨并构建了基于云化EPC资源的移动CDN 融合网络架构，利用虚拟化技术实现MCDN 服务节点资源共享和系统扩展，提高LTE 核心网和CDN系统的可靠性和效率。

关键词: EPC, 移动内容分发网络, 核心网

Abstract:

Based on the current research on mobile CDN and core network virtualization, the method of deploying CND service nodes on virtualized EPC resources were discussed. First, the deployment solution of MCDN under the LTE was analyzed, as well as the virtualization solution of core net. Then a MCDN integration architecture was proposed on the basis of virtualized EPC resources, which can archive resources sharing and system expansion of MCDN service nodes by using virtualization technology and improve the reliability and efficiency of LTE and CDN.

Key words: evolved packet core, mobile content, distribution network, core net
