This text presents late 1990s research on the architecture and protocols for high-speed networks, focusing on communication support for distributed multimedia applications. The book brings together state-of-the-art research from telecommunication and computer communication experts with that of application designers. The analyses of the chapters, which are presented in this book following more or less a bottom-up approach, offer the reader an indication of the actual trends in the field. Most of the results presented in the papers of this book are based on simulation. The text should prove a useful reference for telecommunication and computer experts, QoS-based application designers, as well as for graduate students in these fields. The 151 references that supplement the chapters pave the way to access the basic results and related works.

Multimedia data streams will form a major part of the new generation of applications in high-speed networks. Continuous media streams, however, require transmission with guaranteed performance. In addition, many multimedia applications will require peer-to-multipeer communication. Guaranteed performance can only be provided with resource reservation in the network and efficient multipeer communication must be based on multicast support in the lower layers of the network. This book focuses on techniques for building the networks that will meet the needs of these multimedia applications. In particular two areas of current research interest in such communication systems are covered in depth. These are the protocol-related aspects, such as switched networks, ATM, MAC layer, network and transport layer; and the services and applications. This text should provide a useful reference for all professionals, engineers and researchers working in the area of high-speed networks.

It is expected that most of the bandwidth in future high-speed networks will be taken up by multimedia applications, transmitting digital audio and video. Traditional networking protocols are not suitable for this as they do not provide guaranteed bandwidth, end-to-end delay or delay jitter, nor do they have addressing schemes or routing algorithms for multicast connections. Presenting recent research on the architecture and protocols for high-speed networks, this work focuses on communication support for distributed multimedia applications. This includes ATM Networking and quality of service for multimedia applications.

High-Speed Networking for Multimedia Applications presents the latest research on the architecture and protocols for high-speed networks, focusing on communication support for distributed multimedia applications. This includes the two major issues of ATM Networking and quality of service for multimedia applications. It is to be expected that most of the bandwidth in future high-speed networks will be taken up by multimedia applications, transmitting digital audio and video. Traditional networking protocols are not suitable for this as they do not provide guaranteed bandwidth, end-to-end delay or delay jitter, nor do they have addressing schemes or routing algorithms for multicast connections. High-Speed Networking for Multimedia Applications is a collection of high quality research papers which address these issues, providing interesting and innovative solutions. It is an essential reference for engineers and computer scientists working in this area. It is also a comprehensive text for graduate students of high-speed networking and multimedia applications.

High-Performance Networks for Multimedia Applications presents the latest research on the services and protocols for networks providing the communication support for distributed multimedia applications. The need for end-to-end QoS for these multimedia applications is raising the stakes for a powerful shaping and scheduling in the network adapter. It is also creating a need for new services at the ATM layer, CBR and VBR being augmented by UBR, ABR and GFR which have to be evaluated in the TCP/IP environment of today and tomorrow. With the pressure of all the new technologies available today, the backbone architecture needs to be revisited and the success of the TCP/IP must not eliminate the possibility of adding a native ATM access to it. Most of the research in communication services such as IntServ, DiffServ and Native ATM is driven by the requirements of multimedia systems and this book illustrates the new emphasis by bringing telecommunication and computer communication experts together with application designers. This is particularly true for the security issues also addressed here. Last but not least, modeling techniques and mathematical models are essential to assess the performance of the networks to be built and to evaluate next century scenarios unachievable by a simple scaling of today's solutions. High-Performance Networks for Multimedia Applications is a collection of high quality research papers and the in-depth treatment of the subjects provides interesting and innovative solutions. It is an essential reference for telecommunication and computer experts and QoS-based application designers. It is also a comprehensive text for graduate students in high-perforrnance networks and multimedia applications.

This book constitutes the thoroughly refereed postproceedings of the first international workshop organized by the European Network of Excellence on Next Generation Internet, EURO-NGI 2004, held in Dagstuhl Castle, Germany in June 2004.The 16 revised full research papers presented were carefully selected during two rounds of reviewing and improvement. The papers are organized in topical sections on network and capacity planning, medium access and admission control, QoS in wireless networks, and network inter-connection and resource access. The book provides a most relevant presentation of current issues of the next generation Internet in the area of wireless communication for mobile users.

1 Multiagent Engineering: A New Software Construction Paradigm Multiagent systems have a long academic tradition. They have their roots in distributed problem solving in Artificial Intelligence (AI) from where they emerged in the mid-eighties as a distinctive discipline. Research in multiagent systems owes much to the work of Rosenschein on rationality and autonomy of intelligent agents, the European MAAMAW workshop series, and last but not least the famous readings of Bond & Gasser (1988) and Jacques Ferber´s book on multiagent systems (1991). It gained further by a public discussion via the Distributed AI mailing list in summer 1991, when the pioneers of the field compared in much detail the concepts of distributed problem solvers to multiagent systems. Within only five years, a new exciting field of research had been established. Now, 15 years later, the field has matured to a degree that allows the - sults of academic research to be passed on to practical use and commercial exploitation. This potential coincides with a need for much larger flexib- ity of our IT infrastructure in light of its highly distributed character and extreme complexity, but also the global character of the business processes and the large number of business partners due to outsourcing and specia- zation. Many experts claim that multiagent systems are the right software technology for the needed IT infrastructure at the right time. The appeal has much to do with the broad perspectives of multiagent systems research.

This book constitutes the refereed proceedings of the International Workshop on Trends in Distributed Systems, TreDS '96, held in Aachen, Germany, in October 1996.The 21 revised full papers presented were carefully selected from a total of 51 submissions; also included is an invited paper by Sape Mullender and Paul Sijben on quality of service in distributed multimedia systems. Beyond the topic of the CORBA architecture and implementations, the book addresses interoperability issues, formal methods, multimedia communication services, distributed object systems, coordination protocols, reuse, workflow management, etc.

“What a di?erence a year makes – 52 little weeks” This variation of the ?rst line from Dinah Washington’s famous song, which originally reads, “What a di?erence a day makes - 24 little hours,” brings it to the point: Accordingtoallexperts,thepress,andmostpeople’simpressionwearetoday in a serious economic recession. Less than one year ago, we practically lived on the “island of the blessed” (namely, at Networking 2008 that was held on the island of Singapore), or in the famous country where “milk and honey ?ow” (or “where wine and liquor ?ow”). This convenient situation has changed abruptly within less than 52 weeks. It looks like the same kind of problems has emerged in all areas – and the “Networking” area has, of course, been a?ected, too. Looking into the 2009 proceedings, however, you will immediately notice that the manuscripts are largely una?ected by any aspect of the economic c- sis (which should be a bit of a consolation). Apparently, research directions are dictated by a process that is all too sluggish in order to be quickly and radically changed by a “tsunami.” Likewise, the conference itself was prepared in spite of such a crisis.
