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.

The papers in this book present various viewpoints on the design and - plementation of techniques for QoS engineering for Internet services.They were selected from more than 70 submissions to the 1st International workshop on “Quality of future Internet services” (QofIS) organized by COST Action 263. The main focus of the papers is on the creation, con?guration and deployment of end-to-end services over a QoS assured Internet using the IntServ (Integrated Services) and Di?Serv (Di?erentiated Services) models. The main technical p- gramme was completed by two keynote talks: IETF Chair Fred Baker opened the workshop with a discussion on major Internet development directions and Andrew M. Odlyzko of AT&T Labs Research gave the closing talk on Internet charging issues. The presentation of papers was organised in 9 sessions. The emphasis of Session 1 is on an assessment of the essential building blocks for a QoS assured Internet, i.e., queueing and scheduling, which basically de?nes the space for end-to-end services. The papers of this session discuss the bounds we may expect from these building blocks, the issues of queueing and scheduling management, and the parameters we need to tune in a dynamic implementation. Flow control and congestion control cannot be considered without regard to the dominating impact of TCP. The keyword of Session 2 is, therefore, Intern- friendly adaptation. Four papers in this session are complementary and together present an emerging understanding of a basic optimal area for such adaptation.

The 2001 International Workshop on Quality of future Internet Services (QofIS 2001) held in Coimbra, Portugal, organized by COST Action 263, is the second of what we expect will become a series of successful QofIS workshops. The previous workshop was held in Berlin in the year 2000. The areas of interest of QofIS cover the design, implementation and provision of Quality of Service, spanning key issues of current and emerging communication systems such as packet-level issues, flow-level issues, network-level issues, architectural issues, and applications. The emphasis of the QofIS2001 w orkshop is on horizontal (end-to-end) as well as vertical (top-down) provision of quality of services, covering all components of end systems and networks, with the aim of identifying solutions enabling feasible and coherent QoS provision. The QofIS2001 cal l for papers attracted 87 submissions from 23 Asian, Australian, European, North American, and South American countries. These were subject to thorough review work by the Programme Committee members and additional reviewers who carried out their work using a specially built conference system, WebChairing, developed in Coimbra by Flor de Utopia, that allowed full control of the submission and reviewing processes. Based on the comments and recommendations of the reviews, the final programme was defined in a Programme th Committee meeting held at the University of Karlsruhe on June 5 , 2001.

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.

This volume contains the papers from BIOWIRE 2007, the first in a series of wo- shops on the bio-inspired design of networks, and additional papers contributed from the research area of bio-inspired computing and communication. The workshop took place at the University of Cambridge during April 2–5, 2007 with sponsorship from the US/UK International Technology Alliance in Network and Information Sciences. Its objective was to present, discuss and explore the recent developments in the field of bio-inspired design of networks, with particular regard to wireless networks and the self-organizing properties of biological networks. The workshop was organized by Jon Crowcroft (University of Cambridge), Don Towsley (University of Massachusetts), Dinesh Verma (IBM T. J. Watson Research Center), Vasilis Pappas (IBM T. J. Watson Research Center), Ananthram Swami (ARL), Tom McCutcheon (DSTL) and Pietro Liò (University of Cambridge). The program for BIOWIRE 2007 included 54 speakers covering a diverse range of topics, categorized as follows: 1. Self-organized communication networks in insects 2. Neuronal communications 3. Bio-computing 4. Epidemiology 5. Network theory 6. Wireless and sensorial networks 7. Brain: models of sensorial integration The BIOWIRE workshop focuses on achieving a common ground for knowledge sharing among scientists with expertise in investigating the application domain (e. g. , biological, wireless, data communication and transportation networks) and scientists with relevant expertise in the methodology domain (e. g. , mathematics and statistical physics of networks).
