以太网带宽管理机制下TCP性能的建模研究

随着以太网技术的迅速发展，基于以太网的链路层流量控制技术成为流量工程的一个重要组成部分，基于漏桶式流控的以太网带宽控制算法被应用于驻地同环境当中。考虑到互联同中长时TCP业务流量增长迅速这一背景，评估以太网流量控制算法对长时TCP性能的影响有其积极意义。论文通过建模分析的方法，对于NewReno TCP算法在漏桶式带宽控制机制下的性能进行了分析，并通过仿真对结论进行了说明。

Simulation Evaluation of TCP Throughput:A Simple Model of Bandwidth Sharing Mechanism in IEEE 802. 3 Ethernet

With the development of Ethernet,the technique of link-layer based traffic control becomes one part of Traffic Engineering. Meanwhile, as over 70 percents of Internet traffic is TCP, it is necessary to evaluate TCP throughput under traffic control environment. In this paper,a simple model is given to evaluate the performance of long-term Newreno TCP in bandwidth sharing Ethernet. Simulation result shows that the model works well.
