Performance enhancement for impairment-aware SRLG failure protection in wavelength-routed optical networks
With the increase of size and number of shared risk link groups (SRLGs) in WDM networks, path protection tends to have longer working paths and backup paths due to SRLG-disjoint constraints, which makes physic...
