Abstract:

Stream transmission control protocol (SCTP) in the electric power communication network and transmission line can be failed simultaneously onto both fast and reliable Wide-area backup protection action. However, when the primary path failure results in performance degradation and disconnection when error occurs, the problem mentioned above leading Wide-Area backup would not be timely acted. To solve this problem, the main path was analyzed based on delay automatic switching paths comprehensive evaluation method which was based on the primary path automatically switching method. The main path automatically switched Wide-area backup protection of information and communication transmission were also introduced. The NS2 simulation environment is verified. Experiments show that the path-based comprehensive evaluation method of main path automatically switch the primary path reduces time consumption and improves wide-area backup protection communication transmission reliability.

Key words: wide-area backup protection, stream control transmission protocol, primary path handover
