网络的新标准——软件定义网络

New Standard of Network——Software Defined Network

软件定义网络(Software Defined Network,SDN)是网络虚拟化的实现。在软件定义网络中OpenFlow协议是其关键技术,通过该协议将以太网设备的数据平面与控制平面分离,从而实现对网络流量的灵活控制。使网络作为通讯管道变得更加智能,为核心网络及应用的创新提供了良好平台。

Software Defined Network(SDN)is an implementation of network virtualization.Its core technology is to separate the data plane and control plane of ethernet devices through OpenFlow protocol,thus realizing flexible control of network traffic.It makes the network as a communication pipeline become more intelligent and provides a good platform for the innovation of core network and application.
