摘要

电力CDN在智能电网发展及电力信息网应用扩展过程中扮演着网络加速、流量负载、安全防护的重要角色，同时，业务需求对其灵活布置也提出了更高的要求。此外，电力CDN加速节点的扩容面临着运维复杂、资源利用率低的问题。传统的电力CDN架构亟待改革，而能够支撑电力CDN改革需求的是SDN和NFV技术。SDN技术将业务控制从网络数据和传送中抽取出来，更有利于多种业务的快速扩展以及对CDN节点的集中管控。而NFV能基于业务发展对CDN节点进行扩容和资源调度，大大减少资本支出、运营成本、空间和功耗。

Abstract

With the development of smart grid and the increasing of network application within the electric power information network

electric power CDN plays an important role of network acceleration technology

traffic load balancing and network security.However

facing the rapidly changing of application requirements

electric power CDN was required to response to the application deployment quickly and possess flexible application extensibility.In addition

there are some problems on electric power CDN node expansion

such as complex operations management and low utilization rate of resources.It is necessary to reform the traditional power CDN architecture

SDN and NFV technique can support.The data control can be extracted and transmitted by SDN from the network data

so it is conducive to expand a variety of application in power CDN rapidly.And NFV can expand the CDN node capacity and schedule node resources based on the application.It can effectively reduce the capital ecpenditure

storage and power consumption.
