The4th InternationalWorkshoponPeer-to-PeerSystemswasheld atCornellon February 24th and 25th 2005.The IPTPS workshopcontinued to bring together researchersand practitioners from a variety of disciplines, including networking, theory,databases,security,andscienti?ccomputing. Theydescribedexperim- tal ?ndings, discussed challenges, and presented novel techniques. We received 123 submissions. Submissions were limited to 6 pages, one page morethanin previousyears.ThesubmissionswerereviewedbyaProgramC- mitteeconsistingof18internationalexpertsfromacademiaandindustry.Aftera bidding process,each committee member was assigned 20 papers to review, g- erating 3 reviews for each paper. Controversial papers were assigned additional reviewers.Thepaperswerethenrankedbasedonoriginality,technicalmerit,and topical relevance,aswell asthe likelihood that the ideas expressedwouldlead to insightful technical discussions at the workshop. The program chairs suggested a program which was extensively discussed and revised by the entire committee to produce the ?nal program. We accepted 24 papers, which were organized into 8 sessions: Security and Incentives, Search, Multicast, Overlay Algorithms, Empirical Studies, and N- work Locality, and two sessions on miscellaneous topics. Authors revised their submissions for a preproceedings distributed at the workshop. After the wo- shop, the authors revised their papers once more for the proceedings before you.

In distributed computing systems--the software for networks--a system may have a huge number of components resulting in a high level of complexity. That and issues such as fault-tolerance, security, system management, and exploitation of concurrency make the development of complex distributed systems a challenge. The Isis Toolkit has become one of the most successful approaches for building reliable distributed software since its release in 1987. Commercially available since 1990, Isis is used in hundreds of settings, including the New York Stock Exchange, the Electronic Stock Exchange of Switzerland, the data acquisition system of the CERN high-energy physics particle accelerator, VLSI fabrication control systems, the Iridium telecommunication system, database applications at the World Bank, and an Arctic weather environment monitoring system. Isis is also widely used for instructional purposes. This book comprises papers that document Isis and describe its important applications. Many of these are previously unpublished papers that give a broad overview of Isis, provide details of the underlying protocols and theory, and discuss the best ways to exploit Isis features in real applications. This volume will be of use to practitioners developing Isis-based applications, to instructors using Isis in classroom settings, and to researchers who want a single reference source for this important approach to distributed computing.
