摘　　要：文章分析了一种改进的基于分布式的以太网无源光网络的接入结构,根据该结构的特点,在IPACT限制DBA算法的基础上进行改进,设计了两种DBA算法,一种是支持ONU传输的顺序DBA算法,另一种是支持全局考虑机制的DBA算法。The article analyzes an improved access structure based on the distributed ethernet passive optical network, according to the characteristic of the structure, improves the DBA algorithm based on the IPACT restrictions, and designs two DBA algorithms, one is an ordering DBA algorithm which is supporting the ONU transmission, and the other is supporting the overall considering mechanism.

关 键 词：以太网无源光网络 分布式网络结构 动态带宽分配算法
