System organization protocol for flexible multimedia system with QoS guarantee functions

Distributed multimedia system which not only integrates various multimedia information distributed over computer networks and but also provides it the users in accordance with the user's requirement during real-time multimedia communication must guarantee the user requested quality of services (QoS) even though the computer and network resources change dynamically or statically. We have proposed a flexible multimedia system which is based on agent-oriented architecture and is able to organize required functions itself. Moreover, the system provides both real time and stored multimedia information services simultaneously to users even though various user's multimedia environment and the resource utility of computers or networks has been dynamically changed. This paper describes about the FMS architecture for multimedia teleconferencing system with QoS guarantee functions, and introduces organization protocols and QoS negotiation protocols. In multimedia teleconference service, FMS is able to realize the multimedia communication services flexibly for service requests and QoS requests from users.
