| 摘 要： | 上行方向的多址接入控制是无源光纤网（ＰＯＮ）中的一个关键问题。提出了一种改进的动态ＴＤＭＡ（时分多址联接）的具体实现方案，使上行业务的平均等待时延与光网络单元（ＯＮＵ）中的缓冲器长度大大缩短，系统性能明显改善，同时在测距上也提出了一种新算法。并提出了一种与传统方法不同的等效分析法对多队列的排队系统的平均等待时延作了具体的分析，给出了模拟结果。

| Abstract: | The upstream multiple access control is a key problem in the passive optical networks (PONs). This paper proposes an implement approach of an improved dynamic TDMA (Time Division Multiple Access). This method shorten the average wait time of the packets of upstream services and the length of buffers in ONUs. The analysis of the wait time and some opinion on ranging in PON are also given. |
