MULTI-FAULTS RE-RESTORATION ALGORITHM BASED ON FUZZY SET THEORY IN OPTICAL TRANSPORT NETWORKS
In this paper,we propose a novel re-restoration mechanism based on fuzzy fault set under multi-faults in optical transport networks.This new scheme inherits from our already proposed FFS(fuzzy fault set)based restoration mechanism which is a reasonable trade-off between the recovery success rate and the remaining network risk resources.We mainly consider the link faults in the simulation because link is likely to fail.The survival restoration scheme is divided into two phase: restoration phase and re-restoration phase.The re-restoration phase aims at restoring more DLPs(damaged light paths)by rerouting a small number of already established light paths.The proposed re-restoration mechanism can further improve recovery success rate which has been verified by simulations on the energy efficient multi-domain WSON(wavelength switched optical network)test bed.
