Abstract

This paper highlights the need for sophisticated multicast mechanisms to be provided by transfer protocols in order to support group communication. This need becomes even more evident in the light of the special QOS requirements imposed by multi-media applications. Today's protocols do not provide the broad range of functionality required by these upcoming new applications. From a number of sample applications we derive functionality and performance requirements which have to be provided by the transfer systems. A flexible implementation strategy being capable of dynamically coping with these demands is introduced. Taking the widely used XTP transfer protocol as an example, we show how some of the identified demands are met by this protocol. Furthermore, necessary enhancements are suggested.
