We propose request-based dynamic bandwidth allocation
(DBA) of gigabit passive optical network (GPON). The optical line terminal (OLT)
in GPON grants bandwidth to optical network units (ONUs). ONUs report request
bandwidth which depends on queue lengths of traffic containers (TCONTs) to the
OLT. In the OLT, DBA of GPON supports a request-based polling order to allocate
bandwidth. Our request-based dynamic bandwidth allocation focuses on weight
assignments in the request-based polling order. Weight assignments allocate
bandwidth in proportion to guaranteed and request bandwidth. We use the C
program to simulate results. Simulated results indicate improved performance in
queueing delay when total offered loads are or are not shared uniformly to
