Abstract

We propose a traffic engineering (TE) scheme that uses virtual preemption and configurable survivability to improve the resilience of the emerging-generation GMPLS networks. Virtual preemption ranks the rerouting requests based on bandwidth granularity and, using this ranking, reroutes these requests to allow the highest-bandwidth-demanding requests to be rerouted first with the expectation of achieving higher restorability. Configurable survivability moves the network operating conditions close to a predefined performance pattern and balances the routing configuration to improve the network survivability. Simulation reveals that the proposed TE scheme can increase the survivability of a network and achieve higher restorability while maintaining the signaling efficiency at an acceptable level.
