In this paper we discuss the design and implementation of the BETEUS (Broadband Exchange for Trans-European Usage) communication platform. BETEUS is a project which is aiming at providing a platform for the support of tele-teaching applications. The communication platform is the part of the overall BETEUS platform that provides end-to-end connectivity between BETEUS sites. The realization of the communication platform is constrained by the services available on the European ATM pilot. Since signalling and multicast features have not been available, the BETEUS communication platform implements a pragmatic approach to overcome these shortcomings. Firstly, we utilize a fully-meshed network for connecting BETEUS sites. Secondly, multicast is done in the application itself. As services, both end-toend native ATM and IP connectivity are provided. The BETEUS communication platform complies with certain important application requirements such as throughput and end-to-end delay. In this paper we give more details on each of the topics raised. 1
