Abstract

Traffic grooming, which can efficiently multiplex many low-rate traffic streams into one lightpath, has been a hot topic in the research community. Here adaptive routing and wavelength assignment (RWA) is studied for WDM grooming mesh networks with constraints on the number of transceivers and wavelength continuity. Three adaptive traffic-grooming algorithms are proposed, and a dynamic path-protection traffic-grooming algorithm is also proposed to provide the survivable optical network. The performance of these algorithms is assessed through simulations.
