| 摘 要： | 研究了相关的路径矩阵模型，提出了一种基于回归分析的路径矩阵模型，该模型的核心有三点：一是采用主动注入IPMP探测包对的方法获得时延；二是根据M/M/1排队模型采用最小二乘方法获得回归方程，避免了繁琐的计算，只需测量时延即可获得流量；三是采用主动测量方法获得路径，最终获得全网的路径矩阵。证明了该方法的有效性，并给出了仿真结果。

| Abstract: | In order to manage the whole network, a novel traffic model was proposed based on the regression formula method. The core of model had three parts: (1) acquiring the delay by injecting probe packet train into the network based on Internet Protocol Measurement Protocol (IPMP); (2) deducing regression formula according to M/M/1 queue model; (3) acquiring the path by active measurement. In order to compute regression formula, the coefficients were acquired by the least square method. It is proved that the regression formula method is effective, and the competed traffic error is within 30% by regress formula. |
