摘要

“十二五”期间，国家电网公司信息系统应用不断深化，一级部署的大型管理信息系统数目不断增加，覆盖范围广，用户数量庞大，软硬件资源池、云计算等新技术对电力数据网提出了新的挑战。CDN是一个由分布在不同区域的节点服务器群组成的虚拟网络。CDN将信息资源推向网络边缘，使得客户快速访问到所需的内容。对电力信息业务的加速需求、电力CDN承载要求、关键技术进行了深入剖析。结合电力信息系统架构及电力数据网络，提出二级网络架构三层存储架构的电力CDN体系，深入分析CDN安全防护要求，最后设计开发了电力CDN管控平台和电力CDN实验床。

Abstract

During the“Twelfth Five Year Plan”，with the continuous deepening development of the SGCC information s ystem，the number of large management information system of one-1evel deployment continues to increase，wide coverage，1arge number of users，and new technologies such as the software-hardware resource pool and the cloud computing，brings new challenge to the data network. CDN（content delivery network）is a virtual network consists of the node server group distributed in different regions. CDN push/pull the information resources to the network edge，allow customers to access content faster. A profound analysis of the demand for the electric power information business accelerating，power CDN network load requirements，and key technology，was given. Based on the electric power information system architecture and the electric power data network，the electric power CDN network system was put forward，which had two levels network architecture and three layers CDN network storage architecture. The CDN network safety protection requirements were analyzed；the electric power CDN control platform and the electric power CDN test bed were designed and developed.
