We propose a Traffic Engineering (TE) scheme that uses virtual pre-emption and configurable survivability to improve the resilience of the emerging generation GMPLS networks. Virtual pre-emption 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.
