ATM From Concept to Services

		ATM: From Concept to Services March 19-20, 1996 - Liège
		A. Danthine Université de Liège

Introduction Any new technology or product is an occasion for hype and ATM is no exception. This tutorial is intended for people who are not happy to surf on this technology but want to deep dive into it to be able to evaluate where we are today, where we may go tomorrow and at which pace. This implies a detailed study of the service provided by ATM, as seen by the ITU on one side and by the ATM Forum on the other side. But ATM is not an isolated layer, it has to be integrated in the communication stack of today and of tomorrow when distributed multimedia applications will be widely available. Therefore, a great emphasis will be placed on the integration of the ATM service into the global communication architecture.

André DANTHINE, Professor at the University of Liège since 1967, created a research unit in networking (RUN) in 1972. In 1983, Professor Danthine launched the ESPRIT I Project 73 aiming at the development of a high speed network for the interconnection of heterogeneous LANs on a broad site. This project ended up, in 1989, with the installation, on the Sart Tilman Campus of the University of Liège, of the BWN (Backbone Wideband Network) prototype (more than 18 km of optical fibre with a data rate of 140 Mbps).
In 1990, Prof. Danthine launched a new Esprit project, OSI95, to tackle the problem of the design of a new transport service and protocol (TPX) for multimedia applications in a high speed environment including B-ISDN. In 1991, he joined the RACE Project CIO. It is in the framework of this project that the ATM LAN of RUN has been connnected, at 34 Mbps, to the European ATM Pilot for functional and performance evaluations. Since 1994, Prof. Danthine is also involved in another RACE project, ACCOPI. November 1995 was the starting point of OKAPI, an ACTS project.
Since 1992, Prof. Danthine is the chairman of the COST action 237 on "Multimedia Telecommunication Services".
Prof. Danthine is a member of ACM, of IEEE, of the Editorial Board of "ETT", of the Editorial Advisory Board of the Wiley Series in "Communication and Distributed Systems", editor of several books and proceedings and author of more than eighty papers. Chairman of the TC6 of IFIP from 1979 to 1985, he is Governor of ICCC since 1982. CRB Fellow in 1960, he received the Melchior Salier Prize in 1961, the "Bell Telephone-100th Anniversary" prize in 1983 and the IFIP Silver Core in 1986. In 1993-1994, he was Francqui Professor at the VUB. He is Doctor of Science Honoris Causa of the University of Kent (1991).

This two-day tutorial was presented in Liege in March 1996
