dates for 19th RIPE meeting
by Anne Lord 02 Feb '94

02 Feb '94

Dear RIPE-ers, Good news! We have received confirmation from Pedro Amorim that the 19th RIPE meeting can be held in Lisbon, Portugal. The dates suggested at the 17th meeting were 26-28th September. However they cannot make this date. Pedro has suggested alternatives, of which we *strongly* favour 12, 13 and 14th September. If anyone knows of any major networking conferences scheduled for these dates or any other major clashes that we have overlooked, can you let me know ASAP - otherwise we will try to set the meeting for this date. I would be grateful if you could reply to me within one week, as we would like to confirm as soon as possible, the preferred week to Pedro. Many thanks, Anne ---------- Date: Wed, 02 Feb 94 10:48:07 PRT From: Pedro Amorim <AMORIM%PTEARN.BITNET(a)FRMOP11.CNUSC.FR> To: Anne Lord <Anne.Lord(a)ripe.net> Subject: Re: 19th RIPE meeting in Portugal ? In-Reply-To: Your message of Tue, 01 Feb 1994 16:05:50 +0100 ------- Anne Here are the possibilities: 12, 13 14 September 19, 20 21 September 10, 11 12 October I hope that we will have a decision soon.

The Conference aims at presenting and discussing the state-of-the-art and the evolution of broadband communications, both in the public and private networks. The papers selected for presentation in the Conference cover the key issues of switching, resource management, network control, communication services, testing, quality of service, traffic characterization, traffic control and protocols. Invited talks on the fields of multimedia communication and traffic control and a panel on ATM introducing are also included in the program. The program is the result of the work of the members of the scientific program committee, organizing committee and the referees. The conference is made possible by the sponsoring organizations IFIP and TELECOM Paris and the conference sponsor, the "Louis Leprince-Ringuet Foundation".

RIPE DNS Hostcount January 1994
by Marten Terpstra 01 Feb '94

01 Feb '94

Folks, Please find below the RIPE DNS hostcount for January 1994. - Again a big increase of over 33,000 (or 6%) to 587,118. Again this indicates a doubling of the number of hosts in about one year (Dec 1992 = 284,000, Jan 1993 = 303,000). - We promised last month that we would produce a worldwide hostcount, but due to time constraints we have not been able to analyse the data. You might have seen the new ZONE survey of Mark Lottor of SRI, and we have made a comparison between the two sets of data. This comparison is available as ftp.ripe.net:ripe/hostcount/History/RIPE-SRI - All output is again available at ftp.ripe.net:ripe/hostcount. The large output files have been gzipped this time, to save some disk space and network bandwidth. History again appended below.

Reimersholme Internet eXchange announcement
by Peter Lothberg 29 Jan '94

29 Jan '94

(:- ANNOUNCEMENT OF THE REIMERSHOLME INTERNET EXCHANGE Hereby we prodly announces that resources have been made available to facilitate a continuation of the current pilot Reimersholme Internet eXchange. The Reimersholme Internet eXchange is a 'European Multi Model eXchange' where several exchange concepts are availiable withn the same facility; 1. Demilitarized Zone -------------------------------------------------------- DMZ - using black 10base2 cable - using a multimode FDDI ring - using a multiport repeater - using a multiport transceiver (AUI plug) - using an etherswitch hub 2. Universal Neutral Internet eXchange -------------------------------------------------------- UNIX - using the technology presented by the Pride project during the Ripe meeting. - there is a connector tap avaliable for a route-server 3. Distributed Global Internet eXchange -------------------------------------------------------- D-GIX - using black 10base2 cable - using a multimode FDDI ring - using a multiport repeater - using a multiport transceiver (AUI plug) - using an etherswitch hub - route server that knowns about underlaying payload technology, such as SMDS, 802.3 MAC. 4. Interim Neutral Internet eXchange -------------------------------------------------------- INIX - as not specified by the Ebone D-GIX group - using 802.3 local network technology 5. Internet eXchange Facility -------------------------------------------------------- IXF - as specified in the IXF architecture document - using any media that can transport packets The pilot Reimersholme Internet eXchange invites all interested parties to participate. Facilities including UPS power, environmental support, test equipments, routing traffic analyzers and generators, many fat pipes and 24*7 onsite staffing is avaliable. The Internet eXchange is available, on the basis that the participating parties pays a minimum facility management fee and line costs. The Reimersholme Internet eXchange is part of the current experimental Distributed Global Internet eXchange. A route server with integrated distributed routing registry (using Ripe-81 format) is planned for the second quarter of 1994. Updates are done by sending new entries by E-mail to the server and data integratety and security is maintained using secure/authenticated mail protocols. The distributed routing registry is deployed in order to solve the emerging problems caused by the fact that established routing registrys like the Ripe-NCC are served by network providers who's AUP may restric universal access from users served by other service providers.

While I welcome this paper I think that it is ill judged that a INIX does not also require connection to at least one European D-GIX. As a result an INIX could send all their european traffic via the US.

THE LONDON INTERNET EXCHANGE
by peter＠unipalm.co.uk 24 Jan '94

24 Jan '94

ANNOUNCEMENT OF THE LONDON INTERNET EXCHANGE JANET and PIPEX hereby jointly announces that resources will be made available to facilitate the establishment of the pilot London Internet Exchange. It is planned to have a Route Server at the pilot London Internet Exchange in operation as soon as possible, subject to availability of the appropriate software and infrastructure support. The pilot London Internet Exchange will be available to all interested Internet service providers. The connections at the pilot London Internet Exchange would be made available, during 1994, on the basis that the connecting organisation pays only marginal line and connection costs. It is the intent that the London Internet Exchange will be a part of a Distributed Global Internet eXchange facility.

While I welcome this paper I think that it is ill judged that a INIX does not also require connection to at least one European D-GIX. As a result an INIX could send all their european traffic via the US. Peter Dawe PIPEX I agree with Peter, it would be most unfortunate if Europe-Europe traffic was sent via a GIX in the US, and traversed the Atlantic via any research link. I note that there are recommendations that this not happen, but I am not sure that this is strong enough. For example, because of reciprocity, the UK-US network provision may agree to accept traffic from the US GIX; it may not plan to accept traffic from a European operator who has got to that GIX via another Europe-US route.
