摘要
软件定义网络(Software Defined Network,SDN)是一种全新的网络架构,它的设计理念是将网络的控制平面与数据转发平面分离,并实现可编程化控制。Openflow由美国斯坦福大学于2007年提出,它提供了标准化的接口,采用流表控制方式,将传统网络通信设备的数据转发和路由控制功能分离,是实现SDN的关键技术。从技术内涵、设备模型等方面对SDN进行了深入研究,同时研究了电力数据通信网的实际需求和现存问题,最后对软件定义网络在电力数据通信网中的应用进行了讨论。
Software defined network（SDN） is a new architecture of network.The separation of network control plane and network data forwarding plane and the realization of programmable control is the design concept of SDN.Standford University put forward the concept of openflow in 2007,it provides standard interfaces and separates the data forwarding and routing control function of the traditional network communication equipment by the flow control method.The article makes a deep research on SDN from the aspects of technical connotation,equipment model and etc.It also makes a research on the actual demand and the existing problems of electric power data communication network of which the application of SDN in electric power data communication network is discussed.
