【摘要】 测量端到端路径的有效带宽对于QoS管理,流量工程,拥塞控制,优化网络路由以及改善端到端的传输性能都有重要意义。本文通过分析数据包对的分离时间与背景流量之间的关系, 提出了一种改进的基于包对模型测量端到端路径有效带宽的方法(ABwPP),可以直接测量路径的有效带宽而不需已知瓶颈带宽。NS-2上的模拟实验结果表明,该方法是准确有效的。更多还原

【Abstract】 Measuring available bandwidth on an end-to-end path is important to QoS management, traffic engineering, congestion control, optimizing network routing and improving end-to-end transport performance. This paper analyze the relation between the packet pair dispersion and cross traffic, then present a improved method named ABwPP based packet pair for measuring available bandwidth on end-to-end path, the method can measuring available bandwidth directly without knowing the bottleneck bandwidth. The results of simulation on NS-2 show the method is accurate and efficient.更多还原
