Advancements in Networked Multimedia Group Communication: COST 264 Initiative Overview

The COST 264 initiative (1998-2002) aimed to foster advancements in networked multimedia communication, addressing the growing demand for sophisticated group communications over the Internet. Key focuses included the development of protocols, architectures, and distributed algorithms that facilitate peer-to-peer interactions and efficient multimedia content distribution. The initiative also sought to establish a research community, improve collaboration among European researchers, and align with international standards such as IETF. Significant outcomes included joint publications, workshops, and the establishment of strong links with other research projects.

  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
