摘要

SDN最重要的3个特征是转发控制分离、集中控制和开放接口，现阶段SDN的产品和系统尚未成熟，运营商通过RR+、PCE等技术逐步实现IP网络的集中控制功能，是传统IP网络向SDN演进的有效途径。首先分析了SDN在广域网的应用系统的架构和各层的主要功能，并对其典型应用，如路由优化调度、流量均衡调度及智能化路径管理等进行了说明。

Abstract

Three key points of SDN are decoupling of data plane and control plane，centralized control and open interfaces.Some carriers develop a SDN application system based on RR+ or PCE technology in order to achieve the centralized control function on traditional IP WAN.The architecture and development suggestions of the SDN application system were presented，and some typical functions，such as routing optimizing，traffic balanced scheduling，paths intelligent arrangement and so on，were described.
