摘要：Multimedia in the network has been fully developed. It used in education also has a long history and resources in education network system become very rich. Now, number of multimedia files in school server is still increasing now. How terminal computers in each place in school get multimedia files at fast speed with low energy consumption is a problem worthy to solve. In order to solve the problem, a new method of dynamic algorithm based on PSO (Particle Swarm Optimization) and ACO (ant colony optimization) method has been developed. This method is based on peer to peer mechanism and can be used in school with different network speed area. In the algorithm, the whole network is firstly divided into several subsystems. Each subsystem would be composed of computers with different network speed. One terminal computer would get multimedia files through computers with high network speed. This method can get high speed in fetching multimedia files and decrease energy consumption. The method would be firstly used in the education system then popularize into other systems.
