This paper presents a teleconferencing platform that was developed in the course of the European
project Beteus. The platform features a highlevel programming interface that reduces the application
development effort to a minimum. Platform and applications were deployed over the European ATM
pilot network between sites in Sophia-Antipolis, Lausanne, Zürich, Geneva and Berlin. One of the major
problems was to make the crossconnect based ATM pilot transparent to the applications. This was
achieved with a fully-meshed network of permanent virtual paths interconnecting the ATM LANs of the
project partners. Another major problem was the provision of multicast to the applications. With the
ATM pilot being a hostile environment for IP multicast, the optimum solution here was found to be
sender-based multicast. The paper presents the major features of the application platform and the devel-oped
applications. It describes the network configuration and summarizes the experience gained in field
trials and major events.
