Research on the link traffic based on passive measurement

In order to manage the whole network, a novel traffic model is proposed based on the active probe method. The core of the model has three parts: first, we measure routing probability matrix by injecting probe packet train into the network based on the Internet protocol measurement protocol (IPMP) by Poisson law. Second, we use passive measurement method to acquire sd traffic. Last, we can compute link traffic by means of network tomography. We prove the validity of edge measurement method. Our computing results show the competing link traffic error within about 30% by edge measurement model.
