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.

Key words: traffic model, path matrix, active measurement, IP measurement protocol（IPMP）
