Doing more with less: Multiple-link failure resiliency using shared mesh protection

This paper investigates the practical and economic aspects of building a multiple link failure resilient optical network using ITU-T standards based shared mesh protection schemes. Our results show that practical deployments of multiple link failure resilient networks are feasible using standards based shared mesh protection at a cost typically lower than 1+1 protection scheme, while enforcing sub-SOms protection for high priority services.
