基于SDN与传统路由相结合的网络架构设计

Design of Network Architecture Based on SDN and Traditional Routing Protocol

针对灾区、战场等复杂环境对通信网络性能的高需求,以及传统的冗余繁杂的紧耦合网络架构发展滞后等问题,提出了一种基于SDN架构与传统路由协议相结合的新型网络架构。该架构的设计思想是先由传统路由完成网络初始联通状态的建立,在此基础上再利用SDN架构技术实现对应用业务和通信网络资源的分析感知、计算、评估等。分别对SDN控制器、南北向接口和传统路由协议进行设计。试验结果表明了该方案的优越性,具有重要的应用和参考价值。

In view of the high demand for communication network performance in complex environments such as disaster areas and battlefields,as well as the slow development of the traditional redundant and complex tightly coupled network architecture,a new network architecture based on SDN and traditional routing protocol is proposed.The design idea of the architecture is that the initial state of the network is established by the traditional route,and then the SDN architecture technology is used to realize the analysis,perception,calculation and evaluation of the application services and communication network resources.This paper designs the SDN controller,the north-south interface and the traditional routing protocol.The experimental results show that the scheme is superior,and has important application and reference value.
