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.
