Abstract: To solve the problem of the long failure locating time and achieve rapid failure restoration, a highly reliable distributed protocol is designed based on the principle of signaling mechanism of intelligent network. The failure can be located rapidly by the interaction between adjacent nodes in the tunnel by self-organized method. The synchronized database can be constructed under the table driven routing approach. The results show that with the proposed method, it can achieve rapid schedule of vehicles and tunnel control. The advantage of high speed, low overhead and high network resource utilization can fulfill the requirement of wideband integrated service communications.
