%X Maximum likelihood estimates were often used in the network tomography to identify the loss rate. The time spent on the estimation increased sharply with the size of the network. To overcome the problems caused by MLE, a fast and simple approach was proposed to estimate loss rates. Compared with the previous methods, the proposed one only needed simple arithmetic calculation to determine loss rates, which saved more time than the MLE, and the time spent on the inference do not increased sharply with the size of the network. Through comparison and simulation, it is obtained that the loss inferences match the true results perfectly, and correctly show the loss trend. So the proposed method is very promising in the real network.
