摘要
提出一种多媒体通信机制——服务质量受控型管道,作为基于服务质量的平台层点对点多媒体通信抽象,以支持分布式多媒体应用的描述与开发.给出了服务质量受控型管道的形式定义,详细讨论了其工作过程.该抽象已经成功地应用于分布式多媒体信息点播系统和分布式多媒体信息系统等.实践表明,服务质量受控型管道既可以直接支持点对点多媒体通信,也可以作为多媒体组通信抽象的基础.
In order to support distributed multimedia application description and development, a multimediacommunication mechanism-QoS (quality-of-service)-controlled pipe is presented as a QoS-based platformpoint-to-point multimedia communication abstraction. The formal definitions of QoS-controlled pipe are introduced and its enforcement procedures are discussed in detail. It has been applied to distributed multimedia information-on-demand systems and distributed multimedia systems successfully. Experimental results show that it not only can act as a comprehensive and integrated solution of point-to-point multimedia communication mechanism, but also can act as the basis of multimedia group communication mechanism.
