Differentiated Quality-of-Protection Provisioning in Optical/MPLS Networks
Overview This paper investigates the problem of dynamic survivable lightpath provisioning against single node/link failures in optical mesh networks employing wavelength-division multiplexing (WDM). This paper present a new approach to provisioning lightpath requests according to their differentiated Quality-of-Protection (QoP) requirements. It focuses on one of the most important QoP parameters, namely protection-switching time, since lightpath requests may have differentiated protection-switching-time requirements. For example, lightpaths carrying voice traffic may require 50 ms protection while lightpaths carrying data traffic may have a wide range of protection-switching-time requirements. Numerical results show that, compared to shared-path protection, this approach achieves significant performance gain which leads to remarkable reduction in blocking probability.
