本文介绍了SDN技术的相关概念,结合辽宁电力通信接入网的业务现状,提出了以SDN为基础构建统一的管控平台:以Open Flow为接口标准,定义了控制层和转发层间的通信协议,根据SDN网络的可编程性,实现有限资源的均衡规划。在辽宁电力通信接入网中,构建了基于Open Flow协议的多级流表转发模型,增强了控制层的智能边缘转发能力、骨干网络的高效承载能力以及网络的开放和协同能力,有效实现对电力通信接入网中各个设备的统一管控。
This paper introduces the related concepts of SDN technology and proposes a unified management and control platform based on SDN based on the current business status of Liaoning Power Communication Access Network: Open Flow is the interface standard, which defines the communication protocol between control layer and forwarding layer , According to the programmability of the SDN network, to achieve a balanced planning of limited resources. In Liaoning Power Communication Access Network, a multi-level flow table forwarding model based on the Open Flow protocol is constructed, which enhances the intelligent edge forwarding capability of the control layer, the high carrying capacity of the backbone network and the openness and coordination ability of the network, Unified control of each equipment in power communication access network.
