Mobile agent based multimedia communication system

Using distributed m ultimediasystem whic hcan integrate various realtime and non-realtime media data, it is required end-to-end quality of service (QoS) guarantee functions including QoS adaptation function, when the system users hold a m ultimediaconference and use realtime audio video data in computer netw orks. Ho-sever it is difficult for the system to adapt more than three users required QoS to suitable QoS, when each user communicates to the other user respectively using realtime audio video data. The current feedbac k message algorithms to coitrol and adjust some QoS requests can cause of increase of control messages and there is some possibilit yof network congestion. We have proposed a flexible multimedia system (FMS) which is based on agent-oriented arc hitecture and is able to organize required functions itself. This paper describes a new QoS guarantee functions based on mobile agent in m ulti-media teleconference service using FMS. In order to collect QoS requirements and state information for media processing, concepts of mobile agent which can transfer host to host is one of valid methods for efficient QoS adaptation and reduction of the number of the feedback messages.
