Day to day advance research in next-generation SONET/SDH introduced novel features for generic protocol framing/encapsulation, virtual concatenation, inverse multiplexing, and along with dynamic generalized multi-protocol label switching control architectures have enabled many new service provisioning paradigms. This paper presents a novel multilayer network survivability scheme that emphasize on latest feature to support multiple levels of service survivability and focus on high capability of carrying load and service repercussion. Detailed simulation performance analysis results are also presented along with conclusions and directions for future work. Results from a sample performance evaluation study also are presented to quantify some of the achievable gains.
