This volume constitutes the proceedings of the Third International Conference in Broadband Services and Networks, IS&N '95, held in Heraclion, Greece, in October 1995; this book summarizes at the same time the main results of a group of RACE projects sponsored by the European Commission for several years. To meet the new challenges in broadband communication, service engineering has now emerged as a new discipline strongly related to software engineering; particularly the concepts of object-orientation and open distributed processing are being adopted. The book presents 44 full papers and 8 posters selected from 88 submissions. Among the issues addressed are service architecture, usability, communications management, advanced communication services, security, and service creation.
