Originally published in 1995. The WWW, a global information system which revolutionized the world of information search and browsing via the Internet, was a new phenomenon in the 1990s. This book acted as an authoritative introduction to the concepts and design. It includes a brief history of the origin of the www and information on running pages in HTML as well as specific case studies in projects from academic and commercial projects. A fascinating insight into the early days of widespread internet use, this look at a new communication mechanism showcases the discussions underway at the time about the uses and future of the www.

As more of our lives are spent interacting digitally — sending and receiving payments, interacting on social media, using certified delivery, playing games online, and generally participating in the digital world — the fair exchange of our digital belongings becomes increasingly essential.This book delves into the theory of fair exchange, from the historic to the cutting-edge, and presents a unified framework for understanding fair exchange protocols. Every exchange starts with a handshake, which is followed by four additional operations: deposit; verification; synchronization; and release or restoration. The environments in which these operations take place determine the properties of the resulting protocol, and the characteristics of the items that can be exchanged.Existing protocols are examined through this framework, including escrow-based protocols, optimistic protocols, and gradual release protocols. A new family of fair exchange protocols is developed which make use of attestables, a novel interface for exfiltration-resistant computing. An attestable-based protocol called FEWD is also introduced and several variations are described which are suitable for the exchange of different classes of items.Finally, a number of special topics for fair exchange are introduced, including legal issues that can emerge in practical applications of fair exchange, a legal analysis of the basic operations of fair exchange, commercial applications of FEWD, and an analysis of additional risks including participant expectations and implementations of attestable-based protocols. We conclude with a collection of topics for future research in making fair exchange more ubiquitous in our lives for a fairer digital world.

This book constitutes the refereed proceedings of the First International Workshop on Quality of Future Internet Services, QofIS 2000, organized by COST Action 263 in Berlin, Germany in September 2000. The 28 revised full papers presented were carefully reviewed and selected from more than 70 submissions. The book offers topical sections on queueing and scheduling; TCP, flow and congestion control; end-to-end; traffic engineering and QoS routing; QoS measurements and measurement based on QoS mechanisms; fairness; adaptation; traffic classes and charging; and resource utilization and performance.

This book constitutes the refereed proceedings of the Second International Workshop on Quality of Future Internet Services, QofIS 2001, organized by the European COST Action 263, in Coimbra, Portugal, in September 2001. The 22 revised full papers presented were carefully selected during a competitive reviewing process from a total of 87 submissions. The book offers topical sections on quality of service for multimedia communication, admission control, QoS routing, differentiated services networks, QoS monitoring and mapping, and traffic engineering.

Thisyear'sInternationalWorkshopon NetworkedGroupCommunications(NGC) was the third event in the NGC series following successful workshops in Pisa, Italy(1999),andStanford,CA,USA(2000). Forthetechnicalprogramthisyear,wereceived40submissionsfromboth academiaandindustrialinstitutionsallaroundtheworld.Foreachpaper,we gatheredat least three (and sometimesas many as?ve) reviews. After a thorough PCmeetingthatwasheldinLondon,14paperswereselectedforpresentation and publication in the workshop proceedings. The program continues the themes ofpreviousyears,rangingfromapplications,throughsecurity,downtogroup management,topologicalconsiderations,andperformance. The program committee worked hard to make sure that the papers were not onlythoroughlyreviewed,butalsothatthe?nalversionswereasuptodateand as accurate as could be managed in the usual circumstances. Thisyear,theworkshopwasheldintheLondonZoo,hostedbyUniversity College London (the tutorials having been held at UCL the day before the start of the paper sessions). The proceedings are published by Springer-Verlag in the LNCS series.There are signs that the scope of the NGC workshopsis broadening to include hot topics such as group communication and content networking. We expect to seemoresubmissionsintheseareas,aswellasothernewtopics,forNGC2002, whichistobeheldattheUniversityofMassachusettsatAmhurst,chairedby Brian Levine and Mostafa Ammar. We hope that the research community will ?nd these proceedings interesting and helpful and that NGC will continue to be an active forum for research on networked group communication and related areas for years to come.
