Hybrid protection in WDM networks with shared risk link groups

Hybrid protection in WDM networks with shared risk link groups In wavelength-division multiplexing net- works with shared-risk link groups (SRLGs), it remains as a challenge to provide network protections with low-blocking probabilities and short average protection-swi- tching time. Based on the observation that in networks with SRLGs, link protection frequently helps avoid over-long backup routes and traps, we propose a novel hybrid protection scheme, with the objective of combining the high-average capacity efficiency of shared-path protection with the fast recovery and simple trap avoidance of shared-link protection. Extensive simulation results show that the proposed scheme steadily achieves lower blocking probabilities than both the shared-path and the shared-link protections, while the average protection-switching time is shortened as well. Meanwhile, the signaling and control procedures of the proposed scheme are kept with reasonable complexities. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Photonic Network Communications Springer Journals
