摘要

本文讨论了如何使分布式对象系统具有灵活性，以满足系统环境变化时的应用需求。系统变更被建模为不仅是服务类型的变更，而且是对象支持的服务质量(QoS)的变更。有两种更改对象的方法，一种用于操作对象的状态，另一种用于更改对象的QoS。我们讨论了关于QoS的方法之间的新关系。利用基于质量的关系，讨论了一种基于质量的补偿方法，使目标从不合格状态中恢复。

Flexible distributed systems for multimedia applications

This paper discusses how to make a distributed object system flexible so as to satisfy applications' requirements when changing the system environment. The system change is modeled to be the change of not only types of service but also quality of service (QoS) supported by the objects. There are two types of methods changing the objects, one for manipulating the states of the objects and another for changing QoS of the objects. We discuss new relations among methods with respect to QoS. By using the QoS-based relations, we newly discuss a QoS-based compensating way to recover the object from the less qualified state.
