  Abstract

IEEE ratified IEEE802.3ah as the standard of E-PON, while it leaved the specific method of upstream bandwidth allocation as a role of implementation vendors. Many experts have researched the method of enhancing upstream bandwidth throughput and released related papers. This paper presents another novel mechanism to enhance upstream throughput. This mechanism performs the management of upstream queues by giving the minimum bandwidth of different level to each queue. In order to process packets on each queue we adopted a modified weighted DRR technology. By doing so, the transmission throughput of upstream packets can be largely enhanced. The experimental simulation of this mechanism showed an enhancement of bandwidth utilization more than 10% in comparison to legacy method.
