摘要

本文对GPON基本原理以及MAC层上行链路DBA机制进行了深入分析和介绍。在此基础上

遵照ITU-T规范

提出了一种基于周期轮询的GPON上行链路DBA算法。这种DBA算法

可实现包括五种T-CONT类型

四种带宽分配方式在内的上行链路动态带宽分配

支持多种Qos业务。文中最后

对提出的DBA算法性能进行了简要仿真分析。

Abstract

This paper first introduces the basics of GPON and analyzes the upstream DBA （dynamic bandwidth assignment） mechanisms of the MAC layer. And then a GPON upstream DBA algorithm based upon cyclic polling is proposed according to the ITU-T specifications. The proposed algorithm can support five types of T-CONT and four types bandwidth assignment

thus can support various Qos services. At the end of the paper

the author give a brief analysis of the simulation results of the algorithm.
