Intelligent optical networks support real-time automatic connection configuration and recovery, which give rise to another new set of problems, such as the unsureness of resource reservation and the uncertainty of connection recovery. In view of those facts, we examine current optical network protection and restoration schemes, and propose a connection survivable resource reservation algorithm based on fault simulation. By automatic simulating one link failure or multi share risk link group failures combination, this algorithm can allocate enough backup resources, which make the networks can survive any 1∼3 node or link failures.
