Quality of Service - IWQoS 2003

Quality of Service continues to be an active research eld, especially in the networking community. IWQoS is a successful series of workshops that aims to provide a forum for the presentation and discussion of new research and ideas onQoS.Traditionally,IWQoSworkshopsarecross-disciplinaryandwellfocused, with the emphasis on innovation. As a result, a considerable amount of time is devoted to informal discussion. In addition to the traditional QoS topics such as service guarantees and admission control, this year we aimed to expand the scope of the workshop by encouraging submissions o?ering research contributions related to robustness, resilience, security, and predictability in networking and distributed systems. As a result, the program included two sessions on availability, fault tolerance, and dependability. The other sessions covered routing, resource allocation, storage, Web services, incentives, and rate based QoS. A great deal of e?ort as gone into putting together a high-quality program. The quality of submissions was very high, and the program committee had a di?cult task to select 27 papers among many deserving papers. Special thanks to the program committee, and the outside reviewers, for their e?orts and hard work in the reviewing and selection process during such a short time frame. We thank all authors who submitted papers to IWQoS, and who ultimately made this program possible. We express our appreciation for our sponsors, NSF, the IEEE Communi- tions Society, IFIP WG 6.1, and ACM SIGCOMM & SIGMOBILE.
