多速率系统呼叫级和分组级的损失率分析
摘要
对提供多速率实时VBR业务的系统中呼叫级和分组级的主要性能指标的分析计算进行了深入研究
从多维Markov链的全局平衡条件出发
提出了一种计算在部分共享策略下各业务在线连接数的联合概率分布的方法
在此基础上可算出呼叫损失概率和分组丢失率
仿真结果表明了其准确性。
Abstract
A systematic research on the performance analysis on the call level and the packet level in a system with multi-rate VBR services was made.According to the global balance condition of a multi-dimensional Markov chain
an algorithm of accurately evaluating the probability distribution of on-line connections of each service type in a system with partial sharing policy was proposed.Further
the call blocking probability and the packet loss probability were ob-tained.Simulation results show that the algorithm is accurate.
