光ATM交换单元的排队方案

Queuing Schemes of Optical ATM Switching Elements

根据光ＡＴＭ交换的需要和光缓存器的特点，提出并分析了基于光纤延迟线的３种排队方案，给出了排队算法，通过分析和仿真计算求出信元丢失率和平均时延与延迟线数的关系，并根据所得结果对这３种排队方案进行了比较．

On the basis of the needs of optical ATM switching and the characteristics of optical buffer, three kinds of queuing schemes using optical fiber delay lines and their queuing algorithms are presented. The relations between the number of delay lines and cell loss rate and mean delay are given by means of analysis and computer simulation, and these three kinds of queuing schemes are compared on the basis of the results.
