Abstract
A kind of dynamic wavelength and bandwidth allocation (DWBA) algorithm of WDM-EPON was studied and then improved to guarantee QoS of miltiple-services access. MPCP extention 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.
