Performance Evaluation of Differentiated-resilience Provisioning Scheme for the GMPLS/ASON Networks
The future trend is to integrate a constantly increasing number of services in the GMPLS/ASON networks. Some services have very high resilience requirements, while other services have lower ones. This scenario calls for frameworks capable of provisioning for multiple services in a cost efficient manner. This article proposes a differentiated-resilience provisioning scheme applied to the GMPLS/ASON networks, which expected to be the near-and long-term network technology thanks, among other things, to the great bandwidth capacity offered by optical devices. Finally, a critical evaluation of the state-of-the-art and future challenges facing operators and designers is given. Our numerical results show that the differentiated resilience scenario has better performance than that of dedicated and shared protection and received connections in the differentiated-resilience are 31％ higher than that of shared protection and are 60％ higher than that of dedicated protection.
