Fast recovery time and reduced resource utilization are
the two main criteria for determining the quality of
survivability mechanism. Now it is well-known that
link-based protection and path-based protection provide
respectively a short recovery time and reduced use of
resources. To benefit from the both of these saliencies, we
propose in this paper to use these mechanisms
simultaneously. Indeed, demands mandating shorter recovery
time will be protected using link-based protection.
Meanwhile other demands will be protected using pathbased
protection. Simulation results show that the proposed
solution achieves a good trade-off between resource
utilization and recovery time.
