Abstract :
EPON is an emerging local subscriber access network that consists of low-cost point-to-multipoint fiber infrastructure with Ethernet. Because several ONUs use a single shared medium in EPON, it is important to control upstream traffic. An EPON allocates upstream bandwidth to ONUs using a request/permit mechanism. In this paper, we proposed a new DBA algorithm supporting multiple priority queues and evaluated its performance. From the simulation result, we have confirmed that our proposed DBA algorithm can reduce the average queue length in comparison to that of ETRI´s DBA algorithm.
