摘要
讨论了一种基于开放式环境的QoS实现方案,它是在开放系统中资源有限的条件下,为具有QoS需求的应用提供服务。该方案设计了一系列用来描述端到端应用、系统资源特征的抽象结构和QoS的实现算法。其结果解决了开放系统中为支持QoS所引起的诸如系统各层中缺乏QoS的协调表达等一些重要问题。系统还支持QoS动态重协商,能够同时为尽可能多的应用提供服务。
In this paper, a QoS scheme is given to support applications with QoS requirements under resource constraint in open system. Specifically, a series of abstract structure, describing characteristics of end-to-end applications and system resources, as well as algorithms supporting the realization of QoS, are designed in this paper. The scheme addresses common problems found in open systems supporting QoS guarantees, such as lack of harmony QoS expressiveness, ect. In order to let as many as possible applications get system service at the same time, the scheme also supports QoS dynamic degradation.
