From this we have to conclude that at this time there is not enough interest in the service among our current constituency to justify such an ambitious pilot service carried out at the RIPE NCC. I have therefore withdrawn the NCC's proposal. Obviously there is some disappointment because we would have liked to do the job. On the other hand I am quite happy that we did not embark on this project with very short preparation only to find out then that the support was less than expected. We will let you know when TERENA has decided about the award of the SIRCE project. You can then consider supporting the particular effort TERENA will select. I'd also like to thank the 51 people who responded to the questionnaire. Here are the results: n % 51 100 Total 47 92 STI likes that NCC asks feedback this way 46 90 ST9 We are satisfied with current NCC services 44 86 STG questionanaire easy to understand 35 69 STA RIPE should start security coord WG 35 69 ST4 have looked at ripe-150 (proposal) 26 51 ST6 not enough time to consider 22 43 ST5 should have been discussed at RIPE meeting 11 22 STB do not contribute because too vague 11 22 ST2 SIRCE needed in a couple of years 9 18 STF TERENA involvement makes it too complicated 9 18 STE do not contribute because too expensive 7 14 STD do not contribute because we do not need it 6 12 STJ do not contribute until selctin process complete 4 8 ST1 SIRCE not needed at this time 3 6 STC do not contribute because NCC not the right place 3 6 ST8 NCC should not start new services 3 6 ST7 NCC should not do incident coordination 0 0 STH questionnaire took too much time 0 0 ST3 SIRCE not useful at all This further supports that the SIRCE service is currently not perceived as very urgent by many ISPs but that it may become more important in the future. A clear lesson I personally have learned from this is that the consensus building process within RIPE and the NCC contributors committee is a delicate one which takes time and careful consideration by all concerned. It is a good process which has served us very well so far. I will take great care to respect it better than I did in this particular matter. The NCC team and I will now do our best to increase the number of you who are saisfied with our current services from a good 90% to as near to 100% as we can make it. Regards D. Karrenberg

Paul, You asked me to repeat that: if not the telephone system itself- would Christian prepare an analysis saying "a Internet of `appropriate` capacity with RSVP and IPng would allow for concurrent AUDIO (as Jon said) of phone quality for everybody ..." The only problem I have with this phrase is the mention of RSVP. I don't think there is actually any major problem for providing a best effort service dimensioned to fit the needs of 600Mio internauts (or 6 billions, for that matter). I am convinced that some policing will be needed to make sure that usage is proportionate to investments (and subscription rates). I am however definitely not convinced that RSVP is what we need there. RSVP is about giving special priviledges to a few flows; we need to provision sufficient resources so that the average flow has adequate capacity, which is a different problem. -- Christian Huitema

corrected UK figures for October
by Mirjam Kuehne 04 Dec '96

04 Dec '96

Dear all, I forgot to send the updated figures for the October count for the UK. The decrease of hosts that we saw in October was probably due to problems reaching the other TLD UK domains while the hostcount was running. The count was then repeated on Tue, 12 Nov 96 and showed the follwoing results: CY SOA COUNTED DUPL REAL CHANGE ============================================================ "wrong" count for October: uk 31468 697703 98605 599098 -49118 updated count for October: uk 32567 796010 101282 694728 +46512 Please note that this also changes the CHANGE column for the UK for November: uk 34363 815905 106068 709837 +15109 I copied the updated version of the UK hostcount to ftp://ftp.ripe.net/ripe/hostcount/uk.{output,error}-Oct.gz Kind Regards, Mirjam Kuehne RIPE NCC

On a national network (modern) the network is digital and once you are past the codec you don't know whether the call is voice or ISDN data. If you start to do silence suppression on ISDN I suspect that things may go wrong. Internationally you are right - not only do you have silence suppression but also voice compression to 16K. That is why on international ISDN you have to dial 000 rather than 00 for an international call to ensure digital 64K end to end. Interestingly this doubles the cost. Taking into account speech may be compressed and silence suppressed double the cost looks cheap (but don't tell BT). I suspect that 28K modems do not work well internationally and I suspect that the new 56K modems (do we call them modems?) do not work at all.

Peter, congratulations again. - Could anybody help me a bit with SONET/SDH technology: what is the present state of - say STM4c vs STM4 etc.- standardization. At Stuttgart we run some 20km dark fibre driven by FORE`s ATM/STM4c boards (NEC SX4 32 - Cray T3E 512) - would we buy e.g. NORTEL SDH equipment if this would be - say 100km - and what about public European SDH? How is vBNS going to upgrade to 622Mbit/s ? What does the the below "Cisco's Native IP over SDH/VC4" exactly say?

Hostcount for November 1996
by Mirjam Kuehne 03 Dec '96

03 Dec '96

Dear all, Here is the hostcount for November 1996. The table shows an increase since last month of over 82,000 (or 2.5%) to a total of almost 3,450,000 hosts in the DNS in Europe. The UK shows the highest increase for November with more than 110,000 hosts more than in October (Remember the amount of hosts in the UK dropped significantly last month, now it is back to normal :) In some countries we see quite a significant decrease this month, also in countries were the hostcount is done remotely. We couldn't find any explanation for this besides general connectivity problems and servers not responding. Please note that FI consistently loses hosts (hidden behind firewalls?). BA is the first time included in the count. The hostcount can also be found under ftp://ftp.ripe.net/ripe/hostcount. The graphical version of the hostcount can be found at ftp://ftp.ripe.net/ripe/hostcount/RIPE-Hostcount-{Mo,Qu}.eps The translation of the country codes can be found at ftp://ftp.ripe.net/iso3166-countrycodes All this data can also be found at http://www.ripe.net/statistics/ I would like to thank all people who help me to create the hostcount every month by counting hosts locally: at Gerhard Winkler <winkler(a)cc.univie.ac.at> be Herman Moons <Herman.Moons(a)CS.kuleuven.ac.be> ch Marcel Schneider <hostmaster(a)nic.ch> cy Panagiotis Tzounakis <pj(a)ics.forth.gr> cz Jiri Orsag <Jiri.Orsag(a)eunet.cz> de Peter Koch <pk(a)TechFak.Uni-Bielefeld.DE> dk Robert Martin-Legene <robert(a)dknet.dk> es Jose Sanchez-Seco <jose.sanchez(a)rediris.es> fi Petri Ojala <ojala(a)eunet.fi> fr Annie Renard <Annie.Renard(a)inria.fr> gr Dimitris Zisiadis <zisiadis(a)forthnet.gr> hr Ivan Maric <Ivan.Maric(a)stribor.srce.hr> hu Gabor Kiss <kissg(a)sztaki.hu> ie Mike Norris <mnorris(a)dalkey.hea.ie> il Sason Levi <sason(a)NetVision.net.il> it Antonio_Blasco Bonito <bonito(a)nis.garr.it> no Havard Eidnes <Havard.Eidnes(a)runit.sintef.no> pl Irek Neska <irek(a)nask.pl> pt Armando Domingues <fccn(a)dns.pt> ru Andrey Dobrotsvetov <adbr(a)ripn.net> sk Ivan Lescak <Ivan.Lescak(a)Slovakia.EU.net> Lubos Elias <Lubos.Elias(a)uakom.sk> sm Antonio_Blasco Bonito <bonito(a)nis.garr.it> tr Yener Yigit <yener(a)knidos.cc.metu.edu.tr> uk Kevin Hoadley <K.Hoadley(a)nosc.ja.net> Please note, that the next hostcount (December 1996) will be published later than usual, approximately mid January.

More interesting is to se when you can no longer make a normal phone-call, becouse all the resources in the voice switch is consumed by people accessing the Internet with Modems or ISDN. What will they do, improve the voice network (very expensive) or give people real IP services? Once they given people real IP services, well, voice is just an application. --Peter

If ATM was needed to make packets move it would be great, but it's not. It seems to be usable as aa replacement for X.25 and Frame-Relay, for those who buy bandwith and routers and build private networks, but, for a public infrastructure, I don't think so. As the service deleiverd at the endpoint is IP, we need to interconnect the various parts of IP moving clouds, so we will have to have IP-switches (called routers) that go damn fast anyway. So, explain what's the problem here, I just demostrated that you can run production IP traffic at 155Mbit without making a detour through an ATM switch. It has been more stable than any other international circiut we have, and the 'new' technology works great. --Peter
