<p>There is a protection method used in the speakers of the interdomain protocol in the optical netwrok. In the step S102, a master speaker and a backup speaker in the domain are chosen, each of which gathers the node information and routing information in the domain and performs inter-layer communication. In the step S104, the master speaker establishes communication with the backup speaker, and performs routing information critical data backup and status backup. In the step S106, the master speaker and the backup speaker check the living status of each other. If the backup speaker detects the fault of the master speaker, it becomes into the new master speaker and a new backup speaker is chosen, then return to the step S104. If the master speaker detects the fault of the backup speaker, a new backup speaker is chosen, then return to the step S104. If fault doesn't appear in both speakers, then repeat the step S106. The speakers can be efficiently protected, rapidly switched. And the algorithm is less complicated, compact and reliable.</p> |
