Abstract

Passive optical networks (PONs) will be the pervasive choice in the design of next-generation access networks. One possible solution to implementing passive optical access networks is to rely on wavelength-division multiplexing (WDM). Here we investigate the problem of providing real-time service to both hard and soft real-time messages in conjunction with a conventional best-effort service in WDM optical networks based on the single-hop passive-star coupler. We propose an adaptive scheduling algorithm to schedule and manage the message transmissions in the specified network. We have conducted extensive discrete event simulations to evaluate the performance of the proposed algorithm.
