Starting with Napster and Gnutella, peer-to-peer systems became an integrated part of the Internet fabric attracting millions of users. According to recent evaluations, peer-to-peer traffic now exceeds Web traffic, once the dominant traffic on the Internet. While the most popular peer-to-peer applications remain file sharing and content distribution, new applications such as Internet telephony are emerging.Within just a few years, the huge popularity of peer-to-peer systems and the explosion of peer-to-peer research have created a large body of knowledge, but this book is the first textbook-like survey to provide an up-to-date and in-depth introduction to the field.This state-of-the-art survey systematically draws together prerequisites from various fields, presents techniques and methodologies in a principled and coherent way, and gives a comprehensive overview on the manifold applications of the peer-to-peer paradigm. Leading researchers contributed their expert knowledge to this book, each in his/her own specific area.Lecturers can choose from the wide range of 32 tightly integrated chapters on all current aspects of P2P systems and applications, and thus individually tailor their class syllabi. R&D professionals active in P2P will appreciate this book as a valuable source of reference and inspiration.

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.

Peer-to-peer systems are now widely used and have become the focus of attention for many researchers over the past decade. A number of algorithms for decentralized search, content distribution, and media streaming have been developed. This book provides fundamental concepts for the benchmarking of those algorithms in peer-to-peer systems. It also contains a collection of characteristic benchmarking results. The chapters of the book have been organized in three topical sections on: Fundamentals of Benchmarking in P2P Systems; Synthetic Benchmarks for Peer-to-Peer Systems; and Application Benchmarks for Peer-to-Peer Systems. They are preceded by a detailed introduction to the subject.

Discusses the basic characteristics of multimedia operating systems, networking and communication, and multimedia middleware systems. This book provides an understanding of multimedia systems and applications in an integrated manner.
