A Quality-of-Service-Based Point-to-Point Communication Routing Algorithm

QoS(Quality of Service) based network routing mechanisms are fundamental means which can provide QoS guarantees required by distributed multimedia applications. QoS based point to point communication routing mechanisms were discussed in depth. According to the requirements of point to point distributed multimedia applications and Dijkstra algorithm, a one pass hop by hop algorithm was presented and proved. In addition, its simulation software was designed and implemented. The one pass hop by hop algorithm can not only satisfy the needs of QoS based point to point communication routing, but also can be used to set up the initial route for multimedia group communication routing mechanisms.
