SDN环境中多控制器部署策略研究

Research on Multi Controller Deployment Strategy in SDN Environment

SDN实现控制和转发解耦,满足了网络的个性化需求。控制器通过掌握全局网络拓扑,计算出高效的转发策略并下发给数据平面,数据平面负责数据转发。控制器的部署数量和位置在实际应用中对网络性能有直接影响。介绍SDN接口协议,并从控制平面可扩展性、组网方式、搜索算法等方面对多控制部署策略的研究进行总结和分析。

SDN realizes the decoupling of control and forwarding, and meets the personalized requirements of the network. By mastering the global network topology, the controller calculates the efficient forwarding strategy and sends it to the data plane, and the data plane is responsible for the data forwarding. The number and location of the controller＇s deployment have a direct impact on the network performance in practical applications. Introduces the SDN interface protocol, and summarizes and analyzes the research of multi control deployment strategy from aspects of control plane scalability, networking mode, search algorithm and so on.
