Abstract

Ethernet passive optical network (EPON) has been considered as an attractive solution to next-generation broadband access networks due to its low cost and high throughput. However, designing efficient bandwidth allocation algorithms is a critical issue in EPON. In this paper, a novel dynamic bandwidth allocation (DBA) algorithm, called per-slot DBA (PSDBA), is proposed to efficiently and fairly allocate bandwidth among multiple users with different requirements. The PSDBA algorithm is based on the multipoint control protocol (MPCP) and allocates bandwidth on a per-slot basis. It is also combined with queue management to support quality of services (QoS) in the design of an EPON system. The simulation results show that the PSDBA algorithm outperforms a well-known DBA algorithm using a per-frame bandwidth allocation strategy
