Abstract :
This paper studies quantitatively the benefit of startup-failure-driven backup path reprovisioning in terms of connection availability in shared-path-protected optical networks. Numerical results show that shared path protection with startup-failure-driven reprovisioning reduces connection unavailability, and is most efficient when the capacity utilization during the no-failure phases is around 60%.
