PON上行带宽的改进分配方案

A improved scheme based on upstream bandwidth for PON

文章在介绍PON(无源光网络 )的基础上提出了PON上行带宽的一种改进分配方案———动态微时隙 (mini-slot)分配的动态时分复用分组预约多址访问协议 (PRMA/DTDMA) ,对该协议的性能进行了分析 ,实验结果表明动态微时隙分配方案的平均信元接入时延 ,上行带宽使用效率和信元丢失率等性能指标均优于最小分配方案。

Based on the presentation of PON (Passive Optical Networks), a improved scheme of upstream bandwidth dynamic mini-slot allocation of dynamic TDMA/PRMA for PON is given, a comparison of performance between this scheme and the minimum allocation scheme is implementation by experiment. Many performance, such as the mean cell access delay, the mean cell access delay of real-time service, the efficiency of upstream bandwidth and the cell loss rate, for dynamic mini-slot allocation of PRMA/DTDMA scheme are better than minimum allocation scheme.
