面向智能电网的业务网络传输研究

摘要

Aiming at the problem of high processing latency in software defined networking (SDN),which is complicated in data flow and matching flow table.It needs to meet the delay requirement of the highest priority data and the relatively low.The virtualized rapid transmission network (VRTN) is proposed by SDN virtualization technology and vector switching technology,and the simulation is carried out with OPNET.The simulation results show that VRTN can effectively improve the transmission efficiency of data,and provide a valuable reference for the application of SDN in smart grid.%针对面向智能电网的业务网络传输问题,通过软件定义网络(Software Defined Networking,SDN)的方式不可避免的要处理数据种类繁杂且匹配流表过程中存在较高处理时延,为满足最高优先级数据的时延需求以及相对较低优先级数据的公平性,通过SDN的虚拟化技术及向量交换技术提出虚拟快速传输网络(Virtual Rapid Transmission Network,VRTN),并用OPNET进行仿真.仿真结果证明VRTN能够有效的提高数据的传输效率,为SDN在智能电网中的应用研究提供有价值的参考.
