Abstract
Because of the change of the society-information-flow type and the coming of fast-transpotation era, the requirement of the network is steadily on the increase, and the one of the delivering speed and bandwidth also become higher and higher. But there is no infinite bandwidth to be provided to the traffic transmission. Therefore, how to use network most efficiently with limited resource is the main purpose. And most of type of traffics is multimedia now; that is the combination of sounds, images, data, pictures...etc. How to transfer to each node efficiently and quickly will be a big challenge.To bring out the fastest traffic transmission, this research constructs the routing table to search routing quickly. Besides, on considering the calculation and location of bandwidth, and routing selection is separate in traditional way, but there will be such a weakness that it could just consider the individual optimization, not exactly the whole optimization. So this research considers two mechanisms together to reach the whole optimization. And it’s also going to simulate the actual process of traffic transmission by the simulation software, then to analysis the collected data to identify the feasibility, merit and shortcomings of the heuristic method in this research.
