A CORBA framework for managing real-time distributed multimedia applications

This paper presents a real-time distributed multimedia framework, based on the Common Object Request Broker Architecture (CORBA), that provides resource management and quality of service (QoS) for CORBA applications. The framework consists of multimedia components and resource management components. The multimedia components produce multimedia streams and combine multimedia streams generated by individual sources into a single stream for the users. The resource management components provide QoS guarantees during multimedia transmissions based on information obtained from monitoring the usage of the system´s resources. Experimental results show that the framework provides timeliness and jitter guarantees, and synchronize the streams of multimedia data efficiently.
