摘要: 本文首先引入了描述分組圖像業(yè)務(wù)的突發(fā)業(yè)務(wù)模型;分析了漏桶算法在突發(fā)業(yè)務(wù)輸入時(shí)的性能;研究了各參數(shù)對(duì)業(yè)務(wù)服務(wù)質(zhì)量的影響。研究結(jié)果表明,增大緩沖器容量可以降低信元丟失率,但會(huì)增大時(shí)延和時(shí)延抖動(dòng)。Abstract: A bursty traffic model is introduced in this paper to describe the statistical characteristics of packet video. The performance of leaky bucket algorithm with bursty traffic input is analyzed. The influences of various parameters on QOS (Quality of Service) are investigated. The analysis shows that although loss probability decreases through expanding buffer capacity, delay and delay jitter increase, whose effect on QOS will not be negligible.
