| Summary: | 碩士 === 銘傳大學 === 資訊工程學系碩士班 === 95 === The media can be transferred directly by peer to peer or transmitted by servers in multimedia communication system. Therefore, the multimedia communication system has well scalable and can provide diversified service to meet user requirements. In order to achieve required QoS, we will propose the signaling system architecture which is integrated several signaling protocol including SIP(Session Initiation Protocol), COPS(Common Open Policy Service), RSVP(Resource Reservation Protocol) and MGCP(Media Gateway Control protocol) that can provide QoS requirement for multimedia sessions under different transmission path.
It is feasible to integrate class-based DiffServ core network and flow-based IntServ access network that can achieve end user requirement preferably and benefit scalability. In this thesis, two cases in terms of UA-aware and Server-aware are studied for signaling system architecture under integrated networks.
Finally, we propose a dynamic resource management mechanism that adjusts the allocated resource for different traffic class according to the class transmission variation. According to simulation results, system performance can be improved significantly while high priority data has good service quality.
