Abstract :
Based on the path computation element (PCE) architecture, we propose an export policy constrained segment-shared protection approach called EPCSSP. Under dynamic traffic with different load, the performances results show that EPCSSP not only can completely protect double-link failures but also can make the tradeoffs between the resource utilization ratio, blocking ratio, and protection-switching time.
