IP Multicasting over ATM: The Multicube Approach

This paper gives practical information along with theoretical background on Multicube project design decisions for scalable and reliable multicast service facilitating multimedia interworking of real users over the European ATM pilot. IP multicast mapping is proposed to be performed with the use of a minimal address resolution server serving a special multicast LIS within the ATM LAN. The feasibility of this choice is proved partly by practical experiment partly via simulation. Data applications for CSCW scenarios depend on a reliable information transfer. The Multicube project selected Xy, an X application sharing tool, to study the reliable multicast services provided by the protocols MTP, RMP and SRM.
