摘　　要：首先对GPON中现有的动态带宽分配算法进行了阐述,然后提出了一种有效QoS保证的二端动态带宽分配算法,并给出了该算法的实现流程图。接着针对几种负载下的不同业务吞吐量情况对该算法进行了分析,最后得出了该算法可以满足动态带宽分配公平性的结论。Firstly, in this paper, the current DBA algorithms used in GPON are expatiated. Then the ＂Dual port DBA Algorithm＂ based on QoS guarantee is present, and the flowchart of this algorithm is also shown. Secondly, this algorithm for different service throughput of several kinds of payload is analyzed. Finally, the conclusion that this algorithm can satisfy dynamic bandwidth allocation equitableness is given.
