I guess we made it in 1992! Still not very reliable, but if you have some luck, you may try either Varna.BG.EU.net (134.222.7.2), or 192.92.129.1 (should be danbo.digsys.bg) some day soon... Best Wishes from Bulgaria! Daniel

Olivier, Yes, CA*NET and the CERN traffic to NSFNET were still on the T1 in November. We did register some data losses with the T3 traffic-by-network data in early November, but I suspect that most of the differences that you noted were due to the fact that much of the international traffic did not cross the T3 backbone. Even though the Country report is explicitly labelled as representing only the T3 traffic, I can understand the likelihood of misinterpretation and have removed the report from nic.merit.edu. The upcoming December report should be complete, and I don't expect any problems. If you find something that doesn't make sense, please let me know, and we'll try to track it down.

I suspect Olivier is right. One of Ireland's two Internet gateways reports external traffic as 4.5 Gbytes for Nov 92; it is reckoned that most of this traffic is with and via NSFnet. Hank reports 1.6 Gbytes to and from Ireland, and this may not include some VMnet stuff, but Ireland's other gateway is for NetNews, which seems to average about 1 Gbyte a month or more. I hope you have had a happy Christmas and will have a prosperous new year. Cheers. Mike (voice: +353.1.612748)

I am very sorry to appear as a trouble maker once more but I have very serious doubts about the accuracy of the traffic figures below with respect to the countries served by the CERN-Cornell T1 line in november 1992. With regard to October 92, we measures 34 GBytes for traffic US<-->NL for example, which is twice as much as what is indicated below, and I can give other examples, e.g. Italy, Switzerland, Austria where the statistics below appear to be seriously wrong, i.e. by a factor 2 at least! The only explanation I can offer is that the CERN-Cornell line was still connected to the NSFnet T1 backbone last month, as was also the case for CA*NET, which probably explain why CANADA is less active than Iceland, whereas I remember Canada ranking 2nd some time ago! I personally have nothing against Iceland or Lapeland, but I hope that the december 92 figure will be more accurate, following the dismantling of the T1 backbone on december 2. Since any traffic statistics, in particular the intercontinental ones, may be exploited for purposes other than purely technical ones, I would very much appreciate that due mention of the possible inaccuracy of the traffic figures for some European countries be explicitely and publicly mentioned. With my advance thanks.

NSFnet stats
by Hank Nussbacher 20 Dec '92

20 Dec '92

Just to let everyone know that the NSFnet now has stats by port and country. The info can be found in nis.nsf.net (nsfnet/statistics/1992 t3-9211.country and t3-9211.ports) and I post below the country stats. Thanks to all involved who have listened and have worked to make this happen: <NIC.MERIT.EDU> /nsfnet/statistics/1992/t3-9211.country ************************************************************************* The following statistics represent traffic, broken down by network, during the one-month reporting period. This compilation reflects an effort to capture as much and as accurate data as possible. However, no guarantee is given for the completeness of the data or its accuracy. Please keep these points in mind when using this data: 1) Only traffic traversing the NSFNET backbone service is included. For example, two nets in Europe might exchange a great deal of traffic, but would not appear below because none of the traffic used the backbone service. 2) On September 2, 1991, a sampling method to collect statistics was begun, as management of the sheer volume of data had become untenable. The data in this report is scaled as if all packets had been analyzed. Sampling will not affect the magnitude nor the ordering of the majority of the data in the report, but omissions may occur for extremely low volume entities. 3) Only countries with IP connectivity to the NSFNET backbone service are shown here. Traffic entering through an application gateway (such as mail via uunet or bitnet) will be credited to that gateway's country. 4) The "(unrecognized origin)" category consists primarily of traffic sent from a network not currently defined in Merit/NSFNET's Topology database to a network that is in the database. A non-zero value in the "Out" column of this category indicates networks that have since been removed from the database. 5) The data are ordered by decreasing number of incoming packets in the first table, and by decreasing number of incoming bytes in the second table. 6) Data is tab-delimited for easy loading into spreadsheets. Questions and comments regarding this data should be sent to nsfnet-info(a)merit.edu ************************************************************************* NSFNET T3 Traffic Distribution by Country November 1992 Packet Total: 22,095,693,800 Byte Total: 4,085,444,551,000 Networks: 9,685 Countries: 47 Packets Packets Percentages In To Out From In Out Nets Country Backbone Backbone ==== ===================== ============== ============== ===== ===== 3626 United States 20539748050 19720090850 92.96 89.25 150 Australia 261376550 231969600 1.18 1.05 183 United Kingdom 230836050 295684900 1.04 1.34 45 Sweden 164259450 160723500 0.74 0.73 274 Germany 141866350 188324600 0.64 0.85 41 Finland 135995150 154420300 0.62 0.70 29 Norway 72164450 91095900 0.33 0.41 161 Japan 63905550 63549100 0.29 0.29 3 Iceland 58927500 73053400 0.27 0.33 13 Mexico 52158900 46434650 0.24 0.21 236 Canada 49095000 306951100 0.22 1.39 4054 (unrecognized origin) 47820700 102952100 0.22 0.47 244 France 46383900 89660000 0.21 0.41 6 Denmark 31375800 40147200 0.14 0.18 18 Israel 30874100 38149600 0.14 0.17 28 Korea 26678400 33187250 0.12 0.15 76 Netherlands 22870850 52548050 0.10 0.24 7 Hong Kong 20626150 27382500 0.09 0.12 31 New Zealand 13320250 14616850 0.06 0.07 8 Chile 13210500 17703350 0.06 0.08 28 Brazil 12582100 13945300 0.06 0.06 3 Puerto Rico 11746900 12908200 0.05 0.06 55 Switzerland 10988750 57134600 0.05 0.26 30 South Africa 7588600 9889900 0.03 0.04 93 Italy 5718150 32472800 0.03 0.15 54 Taiwan 3467100 112246000 0.02 0.51 43 Austria 3347500 25087750 0.02 0.11 20 Portugal 3249350 6235000 0.01 0.03 11 Greece 2829750 5095950 0.01 0.02 11 Ireland 1665150 4335650 0.01 0.02 25 Spain 1500550 8325150 0.01 0.04 1 India 1475550 2074100 0.01 0.01 2 Thailand 1006400 1240300 0.00 0.01 1 Argentina 934500 1369400 0.00 0.01 12 Singapore 856750 35009400 0.00 0.16 3 Estonia 783350 1162900 0.00 0.01 10 Belgium 737650 3642200 0.00 0.02 1 Ecuador 503300 521850 0.00 0.00 20 Czechoslovakia 406400 2156200 0.00 0.01 11 Poland 309000 5701500 0.00 0.03 2 Slovenia 143050 207300 0.00 0.00 4 Venezuela 136700 4994600 0.00 0.02 6 Hungary 109200 1044850 0.00 0.00 1 Tunisia 48350 56300 0.00 0.00 1 Latvia 36650 33650 0.00 0.00 1 Luxembourg 15550 94550 0.00 0.00 2 Malaysia 7450 53750 0.00 0.00 1 Croatia 6400 9850 0.00 0.00 Bytes Bytes Percentages In To Out From In Out Nets Country Backbone Backbone ==== ===================== ============== ============== ===== ===== 3626 United States 3874759959550 3509503835000 94.84 85.90 150 Australia 37408344600 57199677950 0.92 1.40 41 Finland 32903180050 22675528900 0.81 0.56 45 Sweden 25272340250 28260920050 0.62 0.69 183 United Kingdom 21508921150 80004317700 0.53 1.96 274 Germany 21362364850 61922783000 0.52 1.52 161 Japan 11637747450 16709804550 0.28 0.41 244 France 10531128850 28654549850 0.26 0.70 29 Norway 7909722350 19900125850 0.19 0.49 3 Iceland 5589222550 17681731950 0.14 0.43 4054 (unrecognized origin) 4538228200 13944473600 0.11 0.34 236 Canada 4429599450 67898239000 0.11 1.66 13 Mexico 3749162950 11148620950 0.09 0.27 18 Israel 3428805000 11403356100 0.08 0.28 76 Netherlands 3223535450 12769613900 0.08 0.31 6 Denmark 3004141700 10302597950 0.07 0.25 28 Korea 2658757950 10321332850 0.07 0.25 55 Switzerland 2060560500 10566275100 0.05 0.26 7 Hong Kong 1228195050 9446487200 0.03 0.23 54 Taiwan 1026363750 27884530450 0.03 0.68 31 New Zealand 935282500 4720038850 0.02 0.12 28 Brazil 929662000 4507641000 0.02 0.11 3 Puerto Rico 893519700 2173422300 0.02 0.05 30 South Africa 882690350 3411293250 0.02 0.08 8 Chile 790497500 5543901400 0.02 0.14 93 Italy 717757100 8790434450 0.02 0.22 20 Portugal 710669900 1338440500 0.02 0.03 43 Austria 383144150 5408831300 0.01 0.13 11 Greece 188586150 1409062350 0.00 0.03 11 Ireland 174839100 1407597900 0.00 0.03 25 Spain 111072050 2279623550 0.00 0.06 1 Argentina 83728450 195588300 0.00 0.00 12 Singapore 81261250 10795247300 0.00 0.26 1 India 76363500 364949250 0.00 0.01 2 Thailand 60789650 134337300 0.00 0.00 10 Belgium 55404150 1023665100 0.00 0.03 3 Estonia 39387000 380217000 0.00 0.01 20 Czechoslovakia 25934600 581140850 0.00 0.01 1 Ecuador 24547500 103400800 0.00 0.00 11 Poland 20961250 1698215550 0.00 0.04 4 Venezuela 8772150 684105150 0.00 0.02 2 Slovenia 6519200 82782600 0.00 0.00 6 Hungary 5526100 157442000 0.00 0.00 1 Tunisia 4018150 5368650 0.00 0.00 1 Latvia 1750200 3436150 0.00 0.00 1 Luxembourg 821550 40154450 0.00 0.00 2 Malaysia 481750 2364300 0.00 0.00 1 Croatia 282400 3047500 0.00 0.00

FYI: Announcement of HEPnet Consortium
by k13＠nikhef.nl 17 Dec '92

17 Dec '92

ANNOUNCEMENT European HEPnet Consortium The leased lines and infrastructure which form the present HEPnet service constitute a major component of international academic and research networking in Europe. In order to provide a formal basis for interaction with other bodies on behalf of HEPnet, the European HEPnet Consortium has been established. It will act as a coordinating and negotiating body for HEPnet activities and will consider the optimization of the use and cost of HEPnet resources. Members of the Consortium are drawn from institutions which have a substantial commitment to HEP networking. Normally they have sole use of, or share a major part of, at least one international leased line for HEP data and file transfer. Both CERN and DESY are members of the Consortium. The Consortium is incorporated into the HEP-CCC (HEP Computing Coordi- nating Committee), so combining within a single body the functions of each. The HEP-CCC will revise its membership and its terms of reference as appropriate to take proper account of its wider role. The Chairman of the HEP-CCC is also the Chairman of the Consortium. A body known as the HEPnet Consortium Executive Board acts as the executive arm of the Consortium and reports through ist Chairman to the Consortium. The Executive Board has five members, namely, the Chairman, Vice Chairman, and Secretary, who are appointed by the Consortium for a two year period, and the convenors of the ECFA HEPnet Requirements Com- mittee and HEPnet Technical Committee of the HEP-CCC, who are ex-officio members of the Board. The objectives and achievements of the European HEPnet Consortium will be reviewed annually. For further information, contact the Secretary, European HEPnet Consor- tium Executive Board, c/o CERN, CH-1211 Geneva 23, Switzerland (E-mail address: EHC-EB(a)CERN.CH)

by Daniele Bovio 11 Dec '92

11 Dec '92

Folks, as the people attending the last RIPE meeting in Paris may remember, I volunteered to chair the network maps group and to kick off once more the discussion on this topic. A list has been created at the RIPE NCC for this purpose: maps-wg(a)ripe.net The list will be used essentially to discuss and find out what we think about the following: * are maps useful or not. * is it worth producing them or not. * should maps be produced centrally (NCC) or in a distributed fashion (various regional networks should provide them) * should/could maps be produced from the RIPE database or not. * what amount of manpower we estimate necessary to produce and maintain network maps (both centrally and distributed). * any other issue related to the production of maps I have forgot and you would like to suggest. (not necessarily in this order ;-)) If you feel interested in discussing these topics please send a mail to: maps-wg.request(a)ripe.net to be added to the list. The idea is to go to the January meeting with a preliminary draft document answering these questions, finalize it in a parallel session, and eventually present the outcome to the RIPE assembly. Best Regards d.

Re: Nsfnet and Ebone stats
by Hank Nussbacher 11 Dec '92

As to Nsfnet: Seems to me that if one is gonna plunk down millions of dollars into a federally subsidized network infrastructure to replace some existing infrastructure - it should at least be upward compatible in all aspects - which includes statistical monitoring and recording. If it is impossible to do now - then someone in NSF/ANS/Merit should come out and say it. As to Ebone: I realize with ciscos it is impossible to do. But we can at least create reports of ifInOctets/ifOutOctets per Ebone backbone link, as well as ifInErrors/ifOutErrors and perhaps the downTrap to see how many times a link goes to the down state and for how long. Data Communications just had an interesting issue with an article about line reliability and it showed that on average in Europe line reliability was around 99.1% as opposed to the CCITT recommendation of 99.6% for intercontinental links and 99.9% for continental links. I have been monitoring my links and find that I average 30 down states a month sometimes for as short as 8 seconds - and Data Communications goes into this as a synchronization problem between PTTs - which use different synch methods - and they can't tell when a link goes down until you call them. Here is an extract from an article I have written for a local computer newspaper: --------------------------------------------- What are the major causes of a digital telecommunications circuit to go out of service? Synchronization and multiplexing signals on high bandwidth international links is more complicated than on slower speed analog links. Synchronizing at the international level is particularly tricky because different carriers (PTTs) often use different signalling schemes. These synchronization problems usually result in a link disruption of under 2 minutes, long enough to force users off a remote application. Due to the fact that different PTTs use different signalling standards, it is close to impossible for PTTs to monitor digital circuits and instead wait for customers to call them to report circuit outages. PTTs usually show higher availability statistics than customers, since they only start their "down clock" when a customer reports the problem, which is often 15-30 minutes after the line has gone down. Interestingly enough, the higher the data speed, the more reliable the digital data circuit (from the INTUG report): Speed Uptime ------ ------ 768kb 99.99% 384kb 99.94 1544kb (T1) 99.94 1024kb 99.9 128kb 99.88 1984kb 99.88 512kb 99.87 2048kb (E1) 99.56 64kb 99.03 256kb 97 Looking at the above table, users would be recommended to stay away from 256kb circuits and to upgrade as fast as possible from 64kb to 128kb circuits. Almost all higher speed lines (other than 64kb and 256kb) meet the CCITT recommendations. --------------------------------------------- All I am saying is that we need some 'minimal' amount of SNMP recording and reporting and I am sure we are all doing this on our own national level so why not expand it to the Ebone?

Take the stairway exit marked "Solinova, Bus, Vysoke skoly". - You will come out of the subway into Solinova Street which will take you directly towards Technicka Street. - take the second left-hand street off Solinova Street - this is Technicka street, where the Technical University is located. - The meeting place (Faculty of Electrical Engineering) is the first building on the right-hand side of Technicka Street. You cannot miss it. b) By train: - take the Underground A-line to the "Dejvicka" terminal station. Use the escalators at the front of your platform and look for the "Solinova, Bus, Vysoke skoly" stairway exit as described above. c) By taxi: - taxi from the Airport to the meeting place should cost approx. 110 Kcs: distance = 13 km; max. price = 8 Kcs/km fixed fee = 6 Kcs - No additional fees should be paid. Please ask for a receipt if in doubt. Directions will be posted inside the Faculty building and there will be people available to point you in the right direction. Public Transport - how much does it cost and where can I get tickets? -------------------------------------------------------------------- Normal ticket price for all types of public transport (Underground, tram, bus, funicular railway) is 4,- Kcs. Tickets should be bought before entering the Underground, tram or bus. You can buy them from supervisors at most entrances to the Underground, or from orange-coloured ticket machines (by the Underground entrances and at many tram or bus stops), or in newspaper kiosks, tobacconists' shops and many food stores. The ticket should be punched IMMEDIATELY after getting on a tram or bus (ask your co-passengers to help you if necessary), and stamped BEFORE entering the Underground premises. Each ticket can be used only once (i.e. a new ticket must be used if you change buses or trams. You can travel any distance on the same ticket if you don't change buses or trams). With the Underground it is slightly different in that your ticket is valid on all Underground lines for one hour. 1-day to 5-day tourist tickets can also be bought mainly in some newspaper kiosks or at Public Transport Offices for 30 Kcs (1-day) to 100 Kcs (5-day); these tickets should not be marked but should be displayed on request.

Re: Nsfnet stats

> As for the Ebone: where can I find statistics such as port usage and > country usage? Port usage, is with the equipment used in Ebone not possible to get, even if you put up a nnstat machine on the DMZ it would not se the traffic switched within a router between it's ports. The T1 network, had one interface per RT-PC and a token-ring interconnecting them, and it was possible to have one dedicated box to do traffic statistics. With todays T3/E3 or FDDI routers, it's not that easy to make all packages avaliable, and have something to analyse them, without basically putting that inside the router hardware. The Ebone as a whole collects only link utalization on a regular basis. However some sites, do collect statistics on source/destination addresses. This is to my knowledge done by Sara in Amsterdam (nic(a)sara.nl) Cern in Geneva (olivier(a)cearn.cern.ch) > Thanks, > Hank -Peter

Nsfnet stats
by Hank Nussbacher 10 Dec '92

10 Dec '92

Is Merit/ANS ever planning to improve the stats that nis.nsf.net delivers? At first they didn't give any T3 stats. Now they give bnss, pnss and delay and all are more or less useless. The T1 reports which showed traffic by port # as well as by country were very valuable. I have read a few times in the Internet Report that work is being done to provide that level of report for the T3 network - but I have been reading this for the past 2 years now. As for the Ebone: where can I find statistics such as port usage and country usage? Thanks, Hank

Termination of GMD's EASInet involvement
by Klaus Birkenbihl 07 Dec '92

07 Dec '92

Hello everybody, as you know GMD was contracted by IBM for EASInet to provide NIC- and NOC-services. Many networks beyond EASInet gained profit from these services since EASInet provided a lot of services for more than 700 networks in Europe. Last week IBM informed us that IBM is not in the position to prolongue this contract. The decision is that IBM-ENC will provide some of the services from next year onward the other services will end Dec. 31st 1992. Since this decision differs from recent plans there is a need for some migration work to bring IBM-ENC into place. So IBM asked us to help to migrate during the first 2 month of 1993. Here are the details (current plan): Service Action TCP/IP-NOC Will be moved to Heidelberg (IBM-ENC) till Feb. 28th 93, IDNX-support Will be moved to Heidelberg (IBM-ENC) till Feb. 28th 93, SNA ends on Dec. 31st, EASInet- Will be moved to Heidelberg (IBM-ENC) till office Feb. 28th 93, any other business ends on Dec. 31st, or will be at IBM-ENC from (EASInet- Jan. 1st. office...) We feel we should thank everybody who helped us to make EASInet a success. The colleagues at IBM for an unburocratic and effective cooperation: thanks to Herb Budd, Harry Clasper, Wolfgang Schroeder for taking care at IBM's Eurocoordination. Thanks to Michael Nies for technical support at the NOC and Peter Streibelt for arranging everything that was needed. We'ld like to thank all EASIsites, esp. the colleagues at CERN. Thanks also to the people from the US: IBM, ANS and MERIT. Too many people to be mentioned here. To all of you: we enjoyed your cooperation folks. Thanks to the EASInet EPC for the guidance and for watching the growth of EASInet. (Of cause we meet on Jan. 11th at GMD. Invitation follows.) And thanks to everybody who used and cooperated with EASInet. Last not least we thank everybody who is (or was before) in GMD's project team: Detlef Straeten, Willi Porten, Stefan Fassbender, Lothar Klein, Irene Schulz and Juan Pizzorno. Hello to everybody - we are out of EASInet but - of cause - we are still busy in networking. Best regards, Klaus Birkenbihl Peter Wunderling Manager Project Manager EASInet Center for Science Networks PS.: This is an informal note of GMD's Center for Science Networks. An official statement will be given by IBM. -+-----------------------------------------------------------------------+- + Center for Science Networks Fax.: +49 2241 14 3002 + + GMD-ISA Tel.: +49 2241 14 3177 + + Rathausallee 10 + + D-5205 Sankt Augustin 1 + + GERMANY + -+-----------------------------------------------------------------------+-
