摘要

文章提出一种适用于千兆以太网无源光网络（EPON）的支持多业务的动态带宽分配（DBA）算法

该算法采用单阈值整帧上报和阈值动态调整解决了EPON中存在的时隙碎片和队头阻塞问题。同时

文章对算法中的关键参数——设定周期的大小与算法性能的关系进行了深入的研究分析

以指导算法设定周期的确定。

Abstract

A Dynamic Bandwidth Allocation（DBA） algorithm supporting the multiple services in Gbit/s EPON is proposed in this paper

which eliminates the unused time slots and HOL blocking in EPON by reporting the total frame amount under a single threshold and dynamically adjusting the threshold.A deepgoing study and analysis are made of the key parameter

i.e.the relationship between the assigned cycle time and the algorithm performance

for conducting the design of the assigned cycle time by the algorithm.
