  1. COST 264 Enabling Networked Multimedia Group Communication Serge FDIDA http://www.lip6.fr/COST264 TCT meeting - June 20-21st, Thessaloniki, Greece

  2. Motivation • Advances in Internet research and technology... • High-Bandwidth, QoS, Local Loop (xDSL, Radio, …) • New Content (video, voice, …) • … will enable sophisticated multimedia multipoint applications • Web-based video distribution, Internet TV, • Tele-collaboration, File distribution, P2P, DIS, etc... • And Overlay networks • CDN : Content Distribution Networks • P2P : Peer-to-Peer

  3. COST264 Rationale • Emerging and increasing demand towards group communication on the Internet • CSCW, Peer-to-Peer (Kazaa, Gnutella), Tele-activities, Internet TV, DIS, Distributed Games, etc… • Lack of protocols to support this need • Communication was considered as unicast • Need for • Architecture, protocols, distributed algorithms • Infrastructure, testbeds

  4. COST264 ID • Starting date : 16 September 1998 • End date : 15 September 2002 • 16 signatories • Area: Multimedia and Internet Communication • Chairman: Serge Fdida, France • Vice-Chairman: WolfgangEffelsberg, Germany • Commission advisor: Remy Bayou • TCT evaluator: Ivar Jardar Aasen • Web site: http://www.lip6.fr/COST264 • Several mailing list: cost264@lip6.fr, official, WGs • Secretariat: Pat Daly, Norcontel

  5. COST264 Objectives • Leverage the European visibility in Internet Research • US is leading research and technology in this area • Build a community of interest • Evaluation metrics • Scientific production • Joint scientific publications • Workshop (NGC) • IRTF and IETF standards • Liaison with IST projects and other COST actions • Joint experimentations

  6. COST264 Working groups • Research on protocols • Research from COST264 organizations • Luigi Rizzo, Pisa, I • Euroseminars • Dissemination of seminars on the “Costbone” • Wolfgang Effelsberg, Mannheim, D • Infrastructure (ended 1/01) • Issues related to the “Costbone” • André Danthine, Liege, B • Liaison IRTF, IETF, IST… • Links with other partners involved in this area • Christophe Diot, Serge Fdida, LIP6, F

  7. Evaluation – Joint activities • Establishment of a research community • Joint work • Meetings : at least two per year • Euroseminars : average of 4 per year • Publications : Many joint papers in HQ C/J • Workshop organization : NGC • Standardization influence : + IETF RFCs • Exchange of researchers : 10 STSMs

  8. Cooperation : Publications • Members publications or editors in the best conferences and journals • Joint papers : • Infocom, NGC, IEEE com Letters, Proms • Journal special issue • IEEE JSAC on Multicast

  9. Dissemination : NGC Workshop • COST264 has established the first International event on Net Group Com • NGC’99 : Pisa (Italy). Nov.99, L. Rizzo. • NGC’00 : Stanford (USA). Nov.00, C. Diot. • NGC’01 : London (UK). Nov.01,J. Crowcroft. • NGC’02 : Boston, Nov.02, B. Levine • The 2003 edition is being scheduled. • Highly succesfful • Published by Springer (LNCS) • Co-sponsored by ACM • Sponsored by industrials (Cisco, Microsoft, Sprint, )

  10. Dissemination : Euroseminars • The COST264 electronic seminar series • Stengthen cooperation among COST264 members • Fast dissemination of new research results • Set- up an overlay multicast backbone • Provide the support for the Euroseminars • How to on the COST web site • Tools like dlb, mlb, Marratech Pro, vic/vat, reflectors • Technical experience

  11. Cooperation : STSM • Establish or continue joint work between COST264 members • Short Term Scientific Missions • Manheim (D) and Inria (F), 99 • Lancaster (UK) and Liège (B), 99 • Paris (F) and Lancaster (UK), 01 • Manheim (D) and UCL (UK), 00 • UCL (UK) and Pisa (I), 01 • Paris (F) and Pisa (I), 02 • IT (Pol) and Manheim (D), 02

  12. Dissemination: Standardization • Strong impact on standards : IETF • +10 IETF drafts …. Some RFCs • Important participation in some IETF groups (RMT, AVT, PIM-SSM, IDMR, ) • Contribution to the success of the multicast PIM-SSM standard • Others: • Strong links to IRTF • Help in hosting the IETF London meeting

  13. Cooperation : COST and IST • Permanent Liaison with COST263 • Liaisons with IST projects • Joint COST264 / GCAP IST meeting • IST LONG, IST CADENUS, 6INIT, … • IST TAPAS (from COST263 and 264) • Participation to many IST projects

  14. Self-Evaluation • High level of scientific contributions • International recognition • Cooperations between members (joint) • Publications, IETF drafts • Conferences and workshop • Euroseminars, STSM • Cooperation with IST and other COST Actions • Difficulties with the « Costbone » and therefore Euroseminars • IP multicast almost unusable across EU countries • End date : 15 september 2002

  15. The future • No follow-on for COST264 although NGC workshop will continue • We have build a joint 263+264 proposal accepted as an IST Thematic Network (8th IST call) : ENET • We have sent an EofI for the 6th Framework : ENEXT • We are planning a proposal for a Network of Excellence build on ENET
