基于软件定义网络的主动配电网通信体系研究

Research on Software Defined Communication Network Architecture in Active Distribution Network

主动配电网的发展对其通信网络的传输带宽、可靠性、接入灵活性等方面提出了更高要求。针对主动配电网通信业务需求,探究软件定义网络(software defined network,SDN)技术的特点,创新性地引入软件定义网络的思想,提出了基于软件定义网络的主动配电通信网络体系架构,充分利用SDN技术灵活、高效、可编程的优势,对基于SDN的主动配电网通信网络关键技术进行研究分析,以满足未来主动配电网业务的通信需求。

The active distributed network system has presented great challenges to the telecommunication network, in terms of bandwidth, reliability and access flexibility. Aiming to deal with these problems, this paper discusses the requirement of communications for the active distributed network and analysis the principle of the software defined network （SDN） technologies. On this basis, the software defined network architecture in active distributed network is proposed, together with key technologies of this proposed communication network architecture, which is able to meet the requirements of the future active distributed network.
