摘要

为平衡大规模网络骨干网上TCP流量模拟的准确性和复杂度

提出模拟接入网出口处的TCP聚集流量

而不从单台主机或会话的层面进行流量模拟。从网络流量的自相似性出发

提出基于应用层和网络传输层自相似的TCP聚集流量模型:在应用层通过聚集多个服从Pareto分布的ON/OFF源模拟生成自相似流量

在网络传输层根据TCP机制实现对应用层流量的聚集传输控制。模拟结果显示

在流量负载比例、流量自相似性以及骨干节点丢包率等方面

模拟结果与采集自某互联网交换中心的实际数据吻合良好

表明了该模型的有效性。

Abstract

To obtain a trade-off between veracity and complexity when simulating TCP traffic of large-scale network

the TCP aggregated traffic of access network in the gateway was proposed as simulated object

instead of the traffic generated at the individual host or session level.Based on the self-similarity of application-level and network-level

the TCP aggregated traffic model was proposed due to the self-similarity of network traffic.The self-similar traffic at application level was generated by aggregating many ON/OFF sources following Pareto distribution.The aggregated transmission control was put on the traffic at network transmission level based on the mechanism of TCP protocol.Compared with the real data collected from a Network Exchange Center

the simulating result shows the validity of the model from the criteria of traffic load proportion

traffic self-similarity

and the packet loss ratio.
