A Corba-based Quality-of-service Management Framework for Distributed Multimedia Services and Applications

چکیده
This paper presents a CORBA-based Quality-of-Service (QoS) management framework for distributed multimedia services and applications. The QoS MIB has been defined for the QoS management of various multimedia services, and consists of information objects that represent a set of layered QoS parameters. These managed objects are organized into four logical groups: service, application, system, and network. We have also defined a set of QoS management services for monitoring and controlling QoS-related resources. Using the designed QoS MIB and management services, we have developed a QoS management system for managing and controlling QoS in a distributed multimedia system called MAESTRO. The prototype management system is Web-based and uses OrbixWeb to interface with the QoS management server which is implemented as a CORBA object, and monitors QoS parameters of distributed multimedia services, which are also implemented as CORBA objects.
