摘要
软件定义网络SDN(Software-Defined Network),或称软件驱动网络SDN(Software Driven Networks)是目前数据中心建设的一个很重要的热点技术,它将网络的控制平面和数据平台相分离,为数据中心的网络控制提供了一种全新的解决方案。对SDN的架构进行了分析,对比了不同的SDN/Overlay覆盖技术实现方法,重点介绍了覆盖(Overlay)方案在控制平面的思路和overlay网络如何与传统网络互通的方法。最后探讨了SDN是未来数据中心的发展趋势。
Software-Defined Network,a very important and hot technology for the data-centered construction,provides a new solution for the control of data center by separating the network control plane and data platform. In this paper,it mainly introduced Overlay network about its thinking in the control plane and the method of communicating the traditional network by analyzing the architecture of SDN and comparing the different methods of SDN/Overlay technology. This paper points out at last that the SDN is the future growing trend of the data center.
