摘要
软件定义网络(SDN),是一种新型网络创新架构,其设计理念是将网络的控制平面与数据转发平面进行分离,并实现可编程化控制,为核心网络及应用的创新提供了良好的平台。结合铁路信息网络现状,分析研究SDN在铁路信息网络发展中的应用前景。
Software Defined Network is a new type of network innovation framework. Its design concept is the separation of control plane and forwarding plane in network and the realization of control, which provides a good platform for the innovation of core network and applications. programmable In light of the status of railway information network, this paper analyzes the application prospect of SDN in the develop- ment of railway information network.
