Towards support for heterogeneous multimedia communications

Today, we are faced with a huge variety of multimedia and collaborative applications, networks and end-systems. The resulting heterogeneous environment imposes new challenges on transport systems. To meet the requirements of heterogeneous receivers in multi-point communication, a communication framework based on a so-called group mediator is outlined. Group mediators are located within the network and provide multicast support for CSCW and multimedia applications. QoS filters are discussed as group mediator modules. Initial work on signalling filter functions is presented.
