基于园区网的SDN控制器设计研究

摘要

SDN网络将传统网络的控制平面和数据平面相分离的特点为未来网络的升级和演进提供了一种全新的思路.在SDN网络中,控制器具有举足轻重的地位,OpenFlow则是其核心技术.文中根据园区网的特点和需求,设计了一款基于OpenFlow的SDN控制器,可以实现对园区网的物理及虚拟网络管理并分析了基于园区网的SDN控制器性能.%SDN network separates the control plane and the data plane of the traditional network.It provides a new way for the future network upgrade and evolution.In SDN network,the controller plays an important role,and OpenFlow is the core technology.According to the characteristics and needs of the campus network,this paper designs a SDN controller based on OpenFlow.The controller can realize the physical and virtual network management of the campus network and it analyzes the performance of SDN controller based on the campus network.
