Paper Abstract

In this paper we propose a new scheduling mechanism that combines priority scheduling with dynamic bandwidth allocation in EPONs. The multi-point control protocol (MPCP) is adopted to facilitate the cooperation between OLT and ONUs. A delta cycle time algorithm (DCTA) is proposed to get adapted to the burst nature of VBR streaming media traffic. An enhanced GATE generation (EGG) method is discussed to increase the channel utilization. Simulation results show that our method leads to significant decrease of packet delay for streaming media traffic especially under heavy traffic load.
