Abstract

All-optical wavelength division multiplexing (WDM) networks are the most promising candidates for the next generation wideband backbone networks. An approach to improve wavelength utilization is to allow multiple sessions share the bandwidth of a wavelength, so time division multiplexing wavelength routed networks are proposed. This paper studies the routing, wavelength and time slot assignment problem in such time-space switched networks with multi-rate traffic. We analyze the problem with a trunk-channel model, and propose an adaptive routing and trunk assignment algorithm. The effectiveness of the proposed algorithm is demonstrated by simulation.
