基于OpenFlow的SDN控制平面可扩展性综述

摘要/Abstract

摘要：

OpenFlow发展之初,主要是为了校园网络研究人员设计其创新网络架构提供真实的实验平台,形成一种新的网络构架SDN。随着其应用范围的增加,遇到的问题逐渐显现出来,尤其是可扩展性方面。文中介绍了OpenFlow的产生背景、特点及发展现状,以及几种较为典型的SDN控制器模型和控制平面框架,并对SDN可扩展性方面遇到的问题及解决方案进行了分析,并概述了其今后的发展方向。

Abstract:

OpenFlow in its early stage has been mainly for researchers to design their innovative network architecture,and provides a real platform on campus.Eventually it forms the new network architecture of SDN.With the increase of its scope in application,its problems have been gradually revealed,especially in scalability.This paper firstly describes the background,characteristics and current development of OpenFlow,analyses some scalability issues and solutions in-depth,and presents several typical SDN controller models and control plane frameworks.Finally,it summaries the future development trend of SDN.

Key words: OpenFlow;SDN;controller plane;controller;placement;scalability
