Abstract :
Network survivability is crucial to optical multicast traffic. We present the optimized design of node-and-link protecting p-cycle with restorability constraints for optical multicast traffic protection. Results show that 100% node and link failure recovery can be achieved at a small amount of additional capacity, compared with the case of 100% link failure recovery.
