Subject: Ebone 92 - REPORT OF GENEVA MEETING TO THE ATTENDEES OF THE EBONE 92 MEETING OF 26/09/91 Please find following a report of the meeting. Kit Miles Secretary to the Ebone 92 Consortium meeting =------------------------------------------------------= Ebone 92 ======== Report of the meeting at CERN, Geneva, 26 September 1991 ======================================================== This is a summary of the meeting held on 26th September 1991 at CERN, Geneva, for those organisations interested in the formation of a consortium to establish a well managed pan-European backbone service - Ebone 92. There were 38 attendees representing 28 organisations. DISCUSSION OF THE EBONE 92 PROPOSAL In the morning session the principles of the Ebone 92 proposal were presented by Kees Neggers. A robust kernel backbone infrastructure is to be created for Internet IP services and ISO-CLNS pilot services by combining and enhancing existing facilities contributed by consortium members for an interim period - 1992 - while full multi-protocol services are being prepared for introduction in 1993. The interested organisations were invited to join the consortium, to be known as the Ebone Consortium of Contributing Organisations (ECCO). Membership of ECCO is based on common interest, vision, and a commitment to contribute. The reactions were enthusiastic for the Ebone 92 approach. The meeting confirmed that managing Layer 3 for IP is an urgent requirement without alternative solution. Many links are shared today and Ebone 92 essentially "renames" these resources and integrates them to provide a managed Layer 3 service. Some attendees would have liked a wider range of services to be offered. It was explained that the feasibility and strength of the Ebone 92 approach lies in limiting the scope to what is achievable in the short term. X.25 backbone services are already provided by IXI: an X.25 service is included in the plans for the Operational Unit services in 1993. The interworking topic was also raised. It was recognised as an important issue in the existing multiprotocol/multidomain environment in which we currently operate. Ebone 92 will not solve this problem. Interworking remains important and should be included in the longer term plans. By linking the IXI and Ebone 92 backbones (via an EBS router) the connectivity for IP can be readily extended to the IXI connected networks. Thus all IXI users can join Ebone 92 and benefit from the managed IP service. There were no questions on the details of the proposal. The meeting agreed that Ebone 92 is a positive and complementary "step in the right direction" towards the full multiprotocol backbone services to be provided by the Operational Unit in 1993. MAKING EBONE 92 POSSIBLE Funding a backbone and balancing expenditure via cost-based pricing is a long term issue currently being investigated by a task force making recommendations for a joint R&D community Operational Unit (see "Towards a single European Infrastructure" 18.09.91). Extracts from the report, showing the level of investment needed to provide a representative backbone topology for multiprotocol services, including X.25, were shown. Line charges dominate the costs. Organisations looking for funding models based on equitable recoveries/subscriptions were referred to the Operational Unit plans and the longer term timescales. Ebone 92 will be made possible by individually determined contributions "in kind" for a limited period. Provision of shared services will take priority over equitable cost distribution. On this basis organisations were requested to consider the form that their contributions would take. Organisations that subsequently join during 1992 will be required to provide the resources to connect plus the incremental operating costs. CONTRIBUTIONS TO EBONE 92 After lunch the first ECCO meeting was held. Organisation representatives from both sides of the Atlantic again expressed their positive support for the initiative and an initial inventory of contributions was made. This included firm commitments plus indications of resources to be made available subject to management confirmation. Clarification of some points was requested and given. Twelve organisations identified specific contributions, the majority of the balance expressed positive intent and three organisations were observing the situation and evaluating their position. It became clear that the "start" backbone configuration can be more extensive than the example given in the Ebone 92 proposal. Offers included: - the hosting and support for an additional backbone site (EBS configuration); - the use of several pan-European links and access to the USA, sufficient for a robust backbone; - equipment for EBS configurations; - legal advice, technical expertise, and staffing budgets exceeding 60K ECU; - administration of a "clearing house". THE NEXT STEPS TOWARDS EBONE 92 Follow up actions were agreed including: - the convening of the Ebone Action Team (EAT) under the chairmanship of Bernhard Stockman to plan the technical implementation; - the preparation of a Memorandum of Understanding / Ebone 92 Consortium Agreement for circulation to intended members; - the establishment of the ECCO on Wednesday 30th October in Amsterdam. Committments for contributions will be collected. From these the initial backbone configuration and the supporting organisation will be formed. IN CLOSING The meeting applauded the initiative of Kees Neggers/SURFnet. Excellent timing. The facilities of CERN and the organisational support of RIPE were much appreciated. =------------------------------------------------------------------------= APPENDIX Organisations present at Ebone 92, 26th September 1991, CERN, Geneva ACOnet Wilfried Woeber wwoeber@tuvie.can.ac.at BelWue Joseph Michl michl@belwue.dbp.de CERN David Williams davidw@cernvm.cern.ch Brian Carpenter brian@priam.cern.ch Francois Fluckiger fluckiger@vxcern.cern.ch DESY Michael Ernst R02ERN@DHHDESY3.BITNET Hans Frese F58FRE@DHHDESY3.BITNET DFN Martin Wilhelm wilhelm@dfn.dbp.de EARN Frode Greisen neufrode@vm.uni-c.dk Daniele Bovio HI@FRORS12.BITNET ECRC/Munich David Morton dave@ecrc.de EUnet Glenn Kowack glenn@eu.net FNC/CCIRN Bill Bostwick bostwick@darpa.mil FORTH Pantelis Tzoktzakis pantelis@GREARN.BITNET IBM Europe Herb Budd Fax: (33) 1 47676969 Harry Clasper Peter Streibelt ICRF Ron Catterall ron@icrf.ac.uk IN2P3 Gilles Farrache farrache@frcpn11.in2p3.fr INFN/GARR Antonia Ghiselli ghiselli@infn.it JANET John Seymour j.seymour@noc.ulcc.ac.uk Phil Jones p.jones@jnt.ac.uk NEN Jean Paul Sauter sauter@FRMOP11.BITNET NORDUnet Peter Villemoes Peter.Villemoes@uni-c.dk Bernhard Stockman boss@sunet.se RAL Paul Bryant peb@ib.rl.ac.uk RedIRIS Ignacio Martinez martinez@iris-dcp.es RENATER Chistian Michau michau@FRORS12.BITNET SPRINT International Gerald Smart Fax: (44) 256 798816 SURFnet Kees Neggers neggers@surfnet.nl SWIPnet Peter Lothberg roll@strul.stupi.se SWITCH Peter Gilli gilli@switch.ch Tele2/Sweden Hans Christer Borgschold hc@tele2.se UCD Dennis Jennings jennings@ucd.ie Michael Norris mnorris@ucd.ie UNI-C Frode Greisen neufrode@vm.uni-c.dk Univ.
