With the developing of the distributed multimedia system, there are many researches about how to reduce the network traffic and how to initialize and gather the distributed multimedia resources. In this paper, we propose a robust system using Intelligent Mobile Agents to construct an automatic and adaptation mechanism for distributed multimedia synchronization and its adaptive Quality of Service (QoS), which is the Distributed Multimedia Synchronization Agent (DMSAgent) system. The DMSAgent system is proposed to improve the efficiency of distributed multimedia network, and to reduce the frequencies of handshaking between client and server by using Intelligent and Mobile Agent technology.
