Route Design for Key Information Auto-Handoff of Remote Terminal in Command Information Net

Reliability is a significant indicator measuring the communication IP nets´ performance. When communication failure occurs in the net, net devices should make a quick detection of the status between contiguous devices, which leads to timely solutions to ensure the communication service. According to the real environment of remote terminal in command information net, under the premise that the two planes back up each other, this dissertation discusses in detail how key information switch from the first plane to the second plane automatically when the link of first plane fails. Utilizing relevant net technology properly, the reliability of the net can be guaranteed with little change to net terminal so as to achieve the management of the communication net.
