Welcome to IWQoS2001 in Karlsruhe! Quality of Service is a very active research field, especially in the networking community. Research in this area has been going on for some time, with results getting into development and finally reaching the stage of products. Trends in research as well as a reality check will be the purpose of this Ninth InternationalW orkshopo n Quality of Service. IWQoS isa ver y successful seriesof workshops and has established itself as one of the premier forums for the presentation and discussion of new research and ideas on QoS. The importance of this workshop series is also reflected in the large number of excellents ubmissions. Nearly 150 papers from all continents were submitted to the workshop, about a fifth of these being short papers. The program committee were very pleased witht he quality of the submissions andh ad the difficult task of selecting the relatively small number of papers which could be accepted for IWQoS2001. Due to the tough competition, many very good papers had to be rejected.

The refereed proceedings of the 10th International Workshop on Quality of Service, IWQoS 2003, held in Berkeley, CA, USA, in June 2003. The 27 revised full papers presented were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on analysis and modeling, resource allocation and admission control, multimedia and incentives, dependability and fault tolerance, routing, availability and dependability, Web services, rate-based QoS, and storage.

We welcome you to the proceedings of IWQoS 2005 held at the University of Passau, in the beautiful state of Bavaria, Germany.

This book constitutes the thoroughly refereed proceedings of the 4th International Workshop on Software Engineering and Middleware, SEM 2004, held in Linz, Austria, in September 2004. The 16 revised full papers presented went through two rounds of reviewing and improvement and were selected from 44 submissions. The papers are organized in topical sections on middleware services, ubiquitous computing, performance and QoS, and building distributed applications.

Due to the dramatic increase in competition over the last few years, it has become more and more important for Internet Service Providers (ISPs) to run an efficient business and offer an adequate Quality of Service. The Competitive Internet Service Provider is a comprehensive guide for those seeking to do just that. Oliver Heckmann approaches the issue from a system point of view, looking not only at running a network, but also at connecting the network with peering and transit partners or planning the expansion of the network. The Competitive Internet Service Provider: Offers an advanced reference on the topic, drawing on state-of-the art research in network technology. Clearly defines the criteria enabling ISPs to operate with the greatest efficiency and deliver adequate Quality of Service. Discusses the implications of the future multiservice Internet and multimedia applications such as Voice over IP, peer-to-peer, or network games. Delivers a comparative evaluation of different feasible Quality of Service approaches. Explores scientific methods such as queuing theory, network calculus, and optimization theory. Illustrates concepts throughout with mathematical models and simulations. This invaluable reference will provide academic and industrial researchers in the field of network and communications technology, graduate students on telecommunications courses, as well as ISP managers, engineers and technicians, equipment manufacturers and consultants, with an understanding of the concepts and issues involved in running a successful ISP.

This volume of the Lecture Notes in Computer Science series contains the set of papers accepted for publication at the colocated QofIS/ICQT 2002 workshops, i.e. the 3rd COST Action 263 International Workshop on Quality of future Internet Services (QofIS) and the 2nd International Workshop on Internet Charging and QoS Technology (ICQT), both of which took place at the ETH Zric h, Switzerland, hosted by the Computer Engineering and Networking Laboratory, TIK. QofIS 2002 was the third in a series of highly successful technical workshops and meetings on Internet services within the framework of the COST Action 263 Q uality of future Internet Services , following previous events in Berlin, Germany in 2000 and in Coimbra, Portugal in 2001. ICQT 2002 was the follow-up to a vivid and extremely well-attended workshop on Internet economics and charging technology that took place within the framework of the Annual Meeting of the German Society for Computer Science (GI) and the Austrian Computer Society in 2001 in Vienna, Austria.

From the basics to the most advanced quality of service (QoS) concepts, this all encompassing, first-of-its-kind book offers an in-depth understanding of the latest technical issues raised by the emergence of new types, classes and qualities of Internet services. The book provides end-to-end QoS guidance for real time multimedia communications over the Internet. It offers you a multiplicity of hands-on examples and simulation script support, and shows you where and when it is preferable to use these techniques for QoS support in networks and Internet traffic with widely varying characteristics and demand profiles.This practical resource discusses key standards and protocols, including real-time transport, resource reservation, and integrated and differentiated service models, policy based management, and mobile/wireless QoS. The book features numerous examples, simulation results and graphs that illustrate important concepts, and pseudo codes are used to explain algorithms. Case studies, basedon freely available Linux/FreeBSD systems, are presented to show you how to build networks supporting Quality of Service. Online support material including presentation foils, lab exercises and additional exercises are available to text adoptors.

What is an 'all-IP' network? What difference will IP networking make to 3G services? Third Generation (3G) mobile offers access to broadband multimedia services - and in the future most of these, even voice and video, will be IP-based. However 3G networks are not based on IP technologies, rather they are an evolution from existing 2G networks. Much work needs to be done to IP QoS and mobility protocols and architectures for them to be able to provide the functionality 3G requires. IP for 3G gives a comprehensive overview of 3G networking functionality and examines how IP protocols can be developed to provide some of the basic building blocks of a mobile system (mobility, QoS and call control) Features: * Clear explanation of how 3G works at the network level. * Review of IP protocol and architectural principles. * Extensive review, classification and analysis of IP mobility protocols - macro and micro- including IPv6. * Analysis of IP QoS protocols and proposed solutions for mobile networks. * Tutorial on SIP (Session Initiation Protocol) and how SIP can be used for multimedia session control. * Description of latest UMTS developments - including Release 5. * Discussion of 4G networks - what does 4G mean? IP for 3G will appeal to mobile telecommunications and network engineers who want to know about future developments as well as system designers and developers. Students and academics on postgraduate courses related to telecommunications, especially 3G networking or IP protocols, will find this text ideal supplementary reading, only assuming a general knowledge of GSM and general networking principles.
