1 COMMUNICATION SYSTEMS The State of the Art

2 IFIP The International Federation for Information Processing lfip was founded in 1960 under the auspices of UNESCO, following the First World Computer Congress held in Paris the previous year. An umbrella organization for societies working in information processing, lfip's aim is two-fold: to support information processing within its member countries and to encourage technology transfer to developing nations. As its mission statement clearly states, lfip's mission is to be the leading, truly international, apolitical organization which encourages and assists in the development, exploitation and application of information technology for the benefit of all people. lfip is a non-profitmaking organization, run almost solely by 2500 volunteers. It operates through a number of technical committees, which organize events and publications. lfip's events range from an international congress to local seminars, but the most important are: The IF1P World Computer Congress, held every second year; open conferences; working conferences. The flagship event is the IFIP World Computer Congress, at which both invited and contributed papers are presented. Contributed papers are rigorously refereed and the rejection rate is high. As with the Congress, participation in the open conferences is open to all and papers may be invited or submitted. Again, submitted papers are stringently refereed. The working conferences are structured differently. They are usually run by a working group and attendance is small and by invitation only. Their purpose is to create an atmosphere conducive to innovation and development. Refereeing is less rigorous and papers are subjected to extensive group discussion. Publications arising from lf1p events vary. The papers presented at the IFIP World Computer Congress and at open conferences are published as conference proceedings. while the results of the working conferences are often published as collections of selected and edited papers. Any national society whose primary activity is in information may apply to become a full member of 1FlP, although full membership is restricted to one society per country. Full members are entitled to vote at the annual General Assembly, National societies preferring a less committed involvement may apply for associate or corresponding membership. Associate members enjoy the same benefits as full members. but without voting rights. Corresponding members are not represented in IFIP bodies. Affiliated membership is open to non-national societies, and individual and honorary membership schemes are also offered.

7 Preface Until recently, communication systems played a minor supporting role in the evolution of computing from mainframes to minis to PCs and servers; today, they are an integral part of almost every aspect of computing, from distributed applications to the Internet. Even experts have trouble keeping up with all of the latest developments in a field that is growing and changing so rapidly. Recognizing the need for researchers and practitioners in all information technology fields to keep up with the state of the art in communications, IFIP's Technical Committee on Communication Systems, TC6, assembled a world-class roster of individual area experts to present a comprehensive "State of the Art in Communication Systems" programme at the 17 th World Computer Congress, which was sponsored by the International Federation for Information processing (IFIP) and held in Montreal, Quebec, Canada in August The papers collected in this book capture the depth and breadth of the field of communication systems, from the basic unicast and multicast routing infrastructure of modem IP-centered data networks, to the middleware services that facilitate the construction of useful distributed systems, to the applications-especially those that take advantage of the world-wide webthat ultimately deliver value to users. The many corollary dimensions of real-world networking are represented here as well, including communication system performance, network management, security, Internet economics, and wireless mobility. In addition to the papers collected in this book, the following two invited talks in the communication systems stream were presented during WCC 2002:
