| 摘 要： | 现有的网络性能估计技术不能实现对路径容量和可用带宽的同时测量。该文通过对存在拥塞链路的路径作随机分析，得到了一种对路径可用带宽的近似估计式，并通过对Kapoor(2004)中的方法进行改进, 提出了一种基于端到端的可以同时对单拥塞路径的容量及可用带宽进行估算的算法。在较准确估算路径容量的同时，达到了用同一组样本实例同时估计路径容量和可用带宽的目的。仿真验证了算法的有效性和准确性。

| Abstract: | Previous capacity estimation techniques can not measure path capacity and available bandwidth simultaneously. In this article an asymptotically-accurate available bandwidth estimators is obtained through a stochastic analysis of a single congested node. Based on the idea some major revisions are made to the algorithm in Kapoor(2004) and a new capacity and available bandwidth estimation method is presented. The method can estimate these two metrics using the same samples group. Simulation validates the theoretical results of the algorithm. |

| Keywords: | Network measurement Packet pair Cross-traffic Path capacity Available bandwidth Delay dispersion |
