摘要
本文提出一个分布式媒体流应用模型DCMM。DCMM以构件和软件代理技术为基础,形式化地定义了媒体流应用系统的软件体系结构,即组成系统的构件和构件之间的交互关系。在该模型中,媒体流应用构件描述与底层协议相分离,实现了媒体流应用的体系结构与网络平台的无关性。该模型允许构件之间以多种方式交互,允许动态地选择网络传输协议,因此具有较好的灵活性。
A Distributed Component based Media stream Model, DCMM, which specifies the composed components and their interactive relationships, is proposed.In DCMM,the components specifications are separated from the transport protocols and the application architecture is independent of the supported networks. Meanwhile, by virtue of allowing the compenents multiple interaction and the permission in choosing transport protocols dynamically, the flexiblity of the model is quite good.
