本文首先指出了在综合话音、数据通信网中话音信息的特点及对综合业务局域网的特殊要求。其次,对话音分组的总时延作了详细分析。最后推导出了在总时延最小意义下的最佳分组长度计算公式。所得结果与试验报导数据相符。
This paper first points out the characteristics of voice information in integrated voice and data communication networks and the special requirements of the integrated service area network. Secondly, the total delay of voice packets is analyzed in detail. Finally, the optimal packet length calculation formula is deduced under the minimum total delay. The result is consistent with the experimental report.
