Abstract :
Traffic grooming, which can effectively use of lightpaths to transmit traffic streams, i.e., to multiplex many low-rate traffic stream into one lightpath to transmit, is gotten more and more research. In this paper, within a WDM grooming mesh networks, under the constraints of the number of transceivers of nodes and wavelength continuity, the adaptive routing and wavelength assignment (RWA) problem is investigated, and some adaptive traffic grooming algorithms are proposed. Simulations and analysis are also given out.
