IQoSM:一种支持多媒体传输QoS服务的框架模型

IQoSM:A Framework Model for Supporting Quality of Service in Distributed Multimedia Systems

随着多媒体应用的发展 ,网络 Qo S保证问题日益突出 ,各种 Qo S服务的策略和算法也层出不穷。如何适应不同应用的特点 ,提出统一的 Qo S框架模型 ,在此基础上根据不同应用需求进行 Qo S策略变换、算法更新 ,是值得深入研究问题。文中提出一种 Qo S管理框架模型—— IQo SM ( Integrated Qo SModel)。 IQo SM模型提供完整的 Qo S管理框架结构 ;各模块相互独立 ,协调合作 ,便于开发。它独立于具体 Qo S算法、策略 ,具有高度的灵活性、可构造性 ,便于算法更新与改造。最后还给出 IQo SM在 CORBAA/ V

With the development of multimedia applications, QoS guarantee technology becomes more important. There are different QoS strategies and arithmetic for different types of multimedia applications. It is useful to study how to make the QoS service adapt to the heterogeneous of distributed applications,how to make it easy to change the QoS strategies and arithmetic according to the types of applications. This paper puts forward a QoS manager object model called IQoSM. It provides an entirely QoS manage framework, every module can be developed independently, and work coordinated. With the IQoSM, people can easily change the QoS strategies and arithmetic without wholly reprogramming and redesigning. It is flexible and easy to be reconstructed. It can also work together with CORBA A/V STREAM mechanism.
