Availability Evaluation in Shared Path Protected WDM Networks with Startup Failure Driven Backup Path Reprovisioning
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%
