Abstract:
This paper discusses how to make a distributed multimedia object system flexible so as to satisfy applications ' requirements in change of 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 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 qualified state.
