Based on the packet-switch network,this paper present a method of computing the end-to-end delay and buffer size. This method is also applied in the multi-media streams situation. In particular,these parameters are used to allow a trade-off between the packet loss rate and total end - to - end delay. 多媒体通信网络 多媒体同步 端到端延迟 缓冲区 multimedia communication network multimedia synchronization buffer total end- toend delay 10.14188/j.1671-8836.2000.01.013 TN919.8 国家863计划资助!（863－306－ZT04－01－1） 2000-01-01 2021-04-01 1
