摘要
主要介绍了多视频源流的组成,以及各模型在不同负载和缓冲器大小的情况下表现的不同状态,从而可以帮助网络工作者根据网络资源的状况选择合适的视频传输模型,进而分析对网络有重要影响的统计特性,以便提高网络性能。
MPEG VBR video streams cannot be moedeled well because of its complexity. The constitution of multiplexed in-put sources and the various effects of different models with the variation of load and buffor sizes are analyzed. Analytic resultscan help network operators to select righ traffic models consequently. The operators can study the statistics characters of net-work and find the most important ones, so can use the network resources effectively.
