Based on the quality of service routing mechanism is an important means to provide quality of service to distributed multimedia applications · Focus on the study of service-based peer-to-peer communication routing mechanism, according to the actual needs of point-to-point distributed multimedia applications and Dijkstra algorithm proposed again Piecewise algorithm is used to prove the correctness of the algorithm. At the same time, the simulation software of the algorithm is designed and implemented. The simulation results show that the algorithm is effective. The one-step algorithm can not only meet the demand of peer-to-peer communication routing based on quality of service, But also for initial routing of multimedia group communication routing mechanisms
