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 STREAM机制上的实现设计
With the development of multimedia applications, network Qo S promises to be more and more prominent. Various Qo S service strategies and algorithms are also emerging. How to adapt to the characteristics of different applications and propose a unified Qo S framework model, on the basis of which Qo S strategy transformation and algorithm updating according to different application requirements, is worth in-depth study. This paper presents a Qo S management framework model - IQo SM (Integrated Qo SModel). The IQo SM model provides a complete QoS management framework; the modules are independent, coordinated and easy to develop. It is independent of the specific Qo S algorithm, strategy, highly flexible, constructable, easy to update and rebuild algorithms. Finally, the design of IQo SM on the CORBAA / V STREAM mechanism is also given
