分布式多媒体系统服务质量管理实现支持机制

Quality of Service Management Implementation Supporting Mechanisms in Distributed Multimedia Systems

近年来，分布式多媒体系统中的服务质量ＱｏＳ（ｑｕａｌｉｔｙｏｆｓｅｒｖｉｃｅ）管理及其实现支持机制取得了很大进展．本文从接纳控制与资源预约、基于速率的流控、差错控制、调度与同步几个方面出发，讨论ＱｏＳ管理实现支持机制，并展望今后的研究工作．

In recent years, great advances have been made in the QoS(quality of service) management and its implementation supporting mechanisms in distributed multimedia systems. In this paper, the QoS management implementation supporting mechanisms are discussed from following aspects: admission control and resource reservation, rate based flow control, error control, scheduling and synchronization. Finally, future research works are proposed.
