Research and Application on the Reliability of PTN Electric Power Communication Network Security Isolation

Along with the development of intelligent electric grid, the access of communication service bring a new challenge to the distribution network communication system, so an integrated communication system is necessary to support channel segregation for carrying a variety of service. In this paper, the PTN security isolation mechanism such as PTN tunnel layer physical isolation, SVLAN business layer logic isolation and interface segregation between information network and communication network was analyzed. By building PTN security isolation simulation experiment network we analyze and judge whether PTN has similar security isolation reliability with SDH network. The security isolation strategy of PTN electric power communication network, interface safety segregation between information network and communication network were formulated.
