| 摘 要： | 该文研究了带比特丢弃的AAL2分组话音复接器缓冲器队列门限值的确定方法,提出用话音分组作为缓冲器队列门限值的单位,给出了确定门限值的计算公式,并对输出链路容量为384kb/s的情况进行了计算机仿真。仿真结果表明,作者提出的门限值的确定方法可获得较小的平均分组时延和较低的平均分组丢失率,计算简便,易于实现,是一种很好的确定缓冲器队列门限值的方法。

| Abstract: | This paper describes two kinds of AAL2 packet voice multiplexers based on input and output bit dropping. An algorithm for determining the bit dropping thresholds using the number of voice packets to determine the thresholds is presented with relevant computation formula. The computer simulation results show that the algorithm presented here is good for determining the bit dropping thresholds with low packet delay and small packet loss probability and easy operation. |
