Wavelength Rerouting in Survivable WDM Networks

Liang, Weifa; Wan, Yingyu


One limitation of all-optical WDM networks is the wavelength continuity constraint imposed by all-optical cross-connect switches that requires the same wavelength be used on all the links along a path. With random arrivals and departures of connection requests, it happens quite often that a new request has to be blocked due to the fact that there are not enough available resources (e.g. wavelength) to accommodate the request. Wavelength rerouting, a viable and cost-effective method, which...[Show more]
