Quality - based Flexibility in Distributed Systems

چکیده
This paper discusses how to make a distributed multimedia object system exible so as to satisfy applications' requirements in change of the system environment. The system change is modeled to be the change of not only for types of service but also quality of service (QoS) supported by the objects. A method changes not only the state of the object but also QoS of the state. We discuss new equivalent and compatible relations among methods with respect to QoS. By using the relations, we newly discuss a QoS-based compensating way to recover the object from the less quali ed state.
