随着分布式多媒体系统在计算机网络上的大量部署，用户的服务质量（QoS）变得越来越重要。本文将其定义为应用QoS，并提出了应用QoS管理系统（QMS）。它通过简单的基于测量的控制方法，根据系统环境控制应用的QoS。质量管理体系包括三种类型的模块。这些是用于模块检测QoS恶化的通知器，用于根据应用程序管理策略决定控制方法的管理器模块，以及用于执行控制的控制器模块。QMS通过分布在网络上的这些模块之间的通信来管理应用程序的QoS。重点研究了QoS管理策略对QMS的设置功能，并提出了设置方法。通过仿真实验，我们证实了该系统能够在多个应用程序之间协商QoS，并能够根据策略对整个应用程序进行管理。
As a large number of distributed multimedia systems are deployed on computer networks, quality of service (QoS) for users becomes more important. This paper defines it as application QoS, and proposes the application QoS management system (QMS). It controls the application QoS according to the system environment by using simple measurement-based control methods. QMS consists of three types of modules. These are a notificator for module detecting QoS deterioration, a manager module for deciding the control method according to the application management policies, and a controller module for executing the control. The QMS manages the application QoS by communicating between these modules distributed on the network. Moreover, this paper especially focuses on the function setting QoS management policies to the QMS and proposes the setting method. By a simulation experiment, we confirmed that the system made it possible to negotiate the QoS among many applications and it was able to manage the whole applications according to the policies.
