This book contains the proceedings of the Third International Network Conference (INC 2002), which was held in Plymouth, UK, in July 2002. A total of 72 papers were accepted for inclusion in the conference, and they are presented here in 8 themed chapters. The main topics of the book include: Web Technologies and Applications; Network Technologies; Multimedia over IP; Quality of Service; Security and Privacy; Distributed Technologies; Mobility; and Applications and Impacts. The papers address state-of-the-art research and applications of network technology, arising from both the academic and industrial domains. The book should consequently be of interest to network practitioners, researchers, academics, and technical managers involved in the design, development and use of network systems.
