Abstract
MAC protocol must be necessarily used because the GPON technology has Point-to-Multipoint structure as connecting an OLT with numerous ONUs. And DBA algorithm must be used to support various services too. There are a few researches in DBA algorithm of GPON, referring the DBA algorithm of BPON which has a waste of bandwidth and the fairness problem between T-CONTs. In this paper, we proposed the BR-DBA algorithm to be able to solve the problems of DBA algorithm on BPON and designed that. As a result of evaluating the performance of BR-DBA algorithm using the NS-2 network simulator, we confirm that the problems of DBA algorithm on BPON were solved and increasing the throughput over BR-DBA algorithm.
