基于SDN控制器的关键技术在IP网络流量调优的可行性研究

摘要

This paper mainly studies the composition and significance of SDN network and SDN controller. And the cases of IP network flow optimization are used to illustrate the advantages of SDN network. Compared with the traditional network and SDN network, this paper expounds the structure of SDN network, the new protocol and the role. This paper analyzes the advantages of SDN network and the problems that need to be solved. The backbone network in IP network is taken as the example to expound the significance of SDN network to the whole network.%主要研究了SDN网络及SDN控制器的组成及产生的意义,并以IP网络流量调优的案例具体说明了SDN网络的优势.从与传统网络与SDN网络相比较入手,阐明了SDN网络的架构,及新产生的协议及作用.着重分析了SDN网络的优势及遇到需解决的问题.以IP网络中骨干网为例,阐述了SDN网络对整个网络的重新架构的意义.
