Design and Implementation of a Flexible Multimedia System with QoS Guarantee Functions

摘要

Distributed multimedia system which not only integrates various multimedia information distributed over computer networks but also provides it to users in accordance with the user's requirement during real time communication must guarantee the user requested quality of services (QoS) even though the computer and network resources change dynamically or statistically. We introduce a flexible multimedia system with QoS guarantee functions, which is based on agent-oriented architecture and provides both real time and stored multimedia information services to users simultaneously even though the multimedia service environment and the resource utilization of computers or networks have been dynamically changed. This paper describes system architecture and its design and implementation of the flexible multi- media telecoference system as one of the application of flexible multimedia system provides both of stored multimedia services and realtime multimedia services to users.
