Research on the link traffic based edge measurement

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