Penetration of high definition (HD) video cameras and broadband networks make us be able to stream easily overHD quality movies onto the Internet. When we distribute the movies each other between some facilities, packet losses caused by cross traffic become a serious problem. This paper proposes an adaptive traffic engineering method by using discrete event simulator. This method searches suboptimal paths combination from the enormous combinations of paths determined from the pairs of all source node and all destination node. We use the cloud computing resource to evaluate these combinations rapidly by which we can utilize powerful computing resource. This method is tested in ns-2 simulation on the 11 nodes network. The results show that proposed traffic engineering method has better adaptability and performance in cross traffic avoidance.
