The communication of information is a crucial point in the development of our future way of life. We are living more and more in an information society. Perhaps the more obvious applications are those devoted to distributed cooperative multimedia systems. In both industry and academia, people are involved in such projects. HPN'95 is an international forum where both communities can find a place for dialogues and interchanges. The conference is targeted to the new mechanisms, prools, services and architectures derived from the need of emerging applications, as well as from the requirements of new communication environments. This workshop belongs to the series started in 1987 in Aachen (Germany), followed by Liege (Belgium) in 1988, Berlin (Germany) in 1991, Liege (Belgium) again in 1992 and Grenoble (France) in 1994. HPN'95 is the sixth event of the series sponsored by IFIP WG 6.4 and will be held at the Arxiduc Lluis Salvador building on the campus of the University of the Balearic Islands in Palma de Mallorca (Spain) from September 13 to 15.
