Important dates: ---------------- Paper deadline: *February 14, 2003* Notification of acceptance: March 24, 2003 Final paper due: April 8, 2003 IWQoS is a successful series of workshops providing an international forum for the presentation and discussion of new research and ideas on quality of service (QoS). The goal of the workshop is to bring together researchers, developers, and practitioners working in this area to discuss recent and innovative results, and identify future directions and challenges, in developing practical systems where predictable and controlled performance is a central requirement. Papers are solicited on all aspects of architecture, algorithm, and protocol design for systems in which QoS requirements are important. In addition to traditional IWQoS topics such as service guarantees and admission control, papers offering research contributions related to robustness, resilience, security, and predictability in networking and distributed systems are particularly solicited. Topics of interest include, but are not limited to: * Scalable QoS architectures * Analytical and simulation models for QoS * QoS control for middleware * QoS-aware programming models and languages * QoS issues in overlay and peer-to-peer networks * QoS issues in ad-hoc networks * Robust and resilient systems * Content delivery networks with service guarantees * Service assurances in wireless and mobile environments * QoS support for information appliances * Modeling user and application QoS requirements * Charging, accounting, and pricing for QoS * Experiences with QoS (measurements, tests, evaluations) IWQoS aims to allow rapid dissemination of research results and to provide fast turnaround. The deadline for papers is therefore as close to the conference as the publishers allow. In the past the workshop has been cross-disciplinary, well focused, with the emphasis on innovation. As a result, a considerable amount of time is devoted to informal discussion.

I don't think loss of info is a tragedy. All this says is that QOS granularity of MPLS is coarser than the QOS granularity of diffserv. When the IP packets leave the MPLS domain, they will still carry their DSCP and can receive diffserv treatment in the downstream IP domain. The fact that several diffserv aggregates may be mixed on a single LSP is no worse than them being mixed on a leased line, which is the standard diffserv model. (In other words, an LSP is a level 2 as far as diffserv is concerned, and diffserv is designed to work over any level 2.) Also, you don't need 64 mappings in practice. A given diffserv domain will only have a few PHBs in use; 8 DSCPs active in one domain (including default) would be a lot, in my view. (OK, there are people who imagine much more complexity, but that leads to a management nightmare.) So it doesn't really matter if the solution to support 64 mappings is clumsy.

There's a sense that something might be needed, but little agreement on why and who will pay. At times the very notion of QoS has seemed to be a pointless waste of time, almost a solution waiting for a problem. This workshop is an opportunity for researchers and practitioners to discuss the history of IP QoS research and development, review what could have been done better (or totally differently), and challenge the industry to think out of the box going forward. Papers are invited that provide well-argued opinion, speculation, or contrary positions. For example: - IP QoS schemes never quite seem complete. Is this just a great research game for academics? - Where's the money? How do we make IP QoS pay when typical Internet applications don't care, and the user's don't know any better? - Will online, multi-player games be the market segment that justifies end-user/access ISP investment in IP QoS tools and solutions? - Isn't more bandwidth the answer? Of particular interest are papers that critique the evolution of IP QoS solutions to date and/or explain what sort of applications and user mindset will need to emerge before IP QoS solutions become cost-effective for ISPs to deploy. A workshop report will be published in a special edition of SIGCOMM Computer Communication Review. Presented papers will be archived in workshop proceedings, and also placed in the ACM Digital Library. WHAT AND HOW TO SUBMIT Papers should be no longer than 10 pages; submissions SHOULD be anonymized as much as practical, but this is not a requirement. If a paper's core message has been published (or accepted for publication) elsewhere the authors must provide new and additional argument and content in order to be considered for RIPQOS. See http://www.acm.org/sigcomm/sigcomm2003/workshop/ripqos/ripqos.html for full submission requirements in the near future.

CALL FOR PARTICIPATION Art-QoS 2003 Workshop on ARCHITECTURES FOR QUALITY OF SERVICE IN THE INTERNET jointly held with THE FINAL AQUILA IST SEMINAR Warsaw, Poland, March 24-25, 2003 Organised by: Institute of Telecommunications Warsaw University of Technology, Poland WORKSHOP PURPOSE The Workshop is organised for bringing together the researchers working on providing Quality of Service (QoS) into IP-based networks. The intention is to discuss architectural and traffic control mechanisms aspects supporting end-to-end QoS. The Workshop is organised jointly with the Final Seminar of the AQUILA IST project. The AQUILA (Adaptive Resource Control for QoS Using an IP-based Layered Architecture) project started in December 1999 with 12 partners from 6 countries (Austria, Finland, Germany, Greece, Italy and Poland). The project has defined a comprehensive framework for the support of QoS in IP-based networks. The proposed solutions were implemented in the form of prototypes and tested in the AQUILA trial sites, in Helsinki, Vienna and Warsaw. During the Workshop there are planned two special sessions devoted to AQUILA. More information about the project one can find at www.ist-aquila.org . WORKSHOP VENUE The Workshop will be held in the Sheraton Warsaw Hotel situated near the centre of Warsaw: www.sheraton.pl PROCEEDINGS EDITION All accepted papers will be published in the form of a book, in the Lecture Notes in Computer Science (LNCS) series by Springer-Verlag. Remark that the paper publication is conditioned by paper presentation at the Workshop.
