A kind of dynamic wavelength and bandwidth allocation (DWBA) algorithm of WDM-EPON
was studied and then improved to guarantee QoS of multiple-services access. MPCP
extension with modified REQUEST message and GRANT message are also proposed. The
simulation results based on OPNET indicates the improved algorithm performed well in
successful QoS assurance.
