Abstract

A novel bandwidth assignment algorithm in WDM Ethernet Passive Optical Networks, called DyWaS-SLA, is proposed not only to provide service differentiation but also to offer subscriber differentiation. Simulation results show that DyWaS-SLA outperforms other bandwidth allocation algorithms in WDM-EPONs as it makes fairer bandwidth distribution than those methods. Consequently, it always insures a guaranteed bandwidth for every priority subscriber. Furthermore, DyWaS-SLA obtains lower mean packet delay and packet loss rate for the highest priority subscribers when compared with other bandwidth distribution schemes in WDM-EPONs.
