摘要/Abstract

摘要： 软件定义网络(Software-defined network,SDN)作为一种新兴的网络范式,通过解耦控制平面与数据转发平面,集中控制并且聚集全网视图,在控制平面与数据平面建立开放接口,启用外部应用使得网络具有可编程性,从而弥补当前网络架构所存在的不足与限制。其中,控制器作为SDN中重要的组成部分,成为了研究的热点。针对软件定义网络控制平面控制器的研究,首先总结了当前SDN控制平面控制器技术发展的现状并对其进行归类；其次着重分析了当前控制器存在的一致性、可扩展性、负载均衡等一系列问题；最后探讨了软件定义网络技术未来的研究发展方向及趋势。

Abstract: Software-defined network(SDN) has emerged as a new networking paradigm by decoupling the control plane and data forwarding plane,and centralized controller and the global view of the network,established a open interface between the control plane and the data plane,and enabled programmability of the network by external applications.It maks up for the lacks and limitations of the current networking infrastructure.Thereinto,controller which is an important component in SDN has become a hot spot.This paper focused on the researches of Software-defined network control plane controller.Firstly,we summarized the current status of SDN control plane controller technology development and classification,and then we seriously analyzed the current existing consistency,scalability,load balancing,and other a series of issues in Software-defined network.Finally,we discussed the SDN technology research and development direction of the future and trend.

Key words: Software-defined network,Multi-controller,Consistency,Scalability,Load balancing
