| 摘 要： | 为了分析流量变化对网络性能可靠性的影响,首先基于信息流动力学建立了通信网络流量模型,在此基础上定义了信息流传输时延和分组丢失率表征网络性能可靠性的指标和评估模型,进而分析了某局域网络在泊松流量和突发性约束流量下的网络性能可靠性。结果表明,2种流量模型下的网络性能可靠性都存在明显相变行为,相变点刻画了网络在性能约束下的最大传输能力。

| Abstract: | To investigate the impact of the amount and change of traffic loads on the performance reliability of network,a simple traffic model for computer networks was established based on the traffic dynamics.The ratio between the ex-pected and the practical delay and the packet loss rate of each demand were used to characterize the performance reliabil-ity of the network.The performance reliability of a special local network was simulated and analyzed using the proposed approach.It was shown that the performance r... |
