Abstract: Multimedia conferencing can be seen as a new way of distributing communication between several applications (rather than a single monolithic application) that often involves more than two end-systems. This can take advantage of multidestination communications services provided by multicast system based on host groups and the enhancement of routers to form special purpose forwarding paths to these groups. This is mainly so that the number of copies of packets sent over mesh topology wide area networks (X.25, IP, or CLNP, as well as SMDS and ATM based WANs) to group destinations may be reduced significantly over a simple replication at source, and so that the service interface is similar to that provided by multicast on networks with a physical broadcast technology (e.g., satellite and LANs). In this paper, we examine the snares and delusions that must be avoided when four different kinds of multicast applications uses a multicast network service, namely: shared window, packet digital audio, packet digital video and shared applications. This is based on the experience of a real (non-toy) system operating over international ISDN links in Europe, and the participation in the (configuration and use of) IETF Internet audio and video casts, to over 200 sites worldwide.
