Re: Caching in Europe?

Mike, I take your point ref: the differences between AFS sharing v. FTP access. And yes, I think members of RIPE are aware of the potential savings esp. here in Europe where bandwidth tends to be very expensive. Then there is also the matter of educating end users - that would also help and I feel we've not done a great job of it.

Dave, AFS does whole file caching at each client, primarily to reduce file server load. In conrtrast, our study suggests placing caches within the network to reduce duplicate transmissions across individual links. AFS evolved from a system originally built to support easy access to files from anywhere in a moderately large university community. In such an environment there isn't much widespread sharing - most files are accessed by one or a handful of users working on a project together, as opposed to thousands of sites retrieving the same popular FTP files. In our study we found that half of all FTP data by volume crossing a particular network link were duplicate transmissions of files that had previously traversed that link. - Mike

Caching in Europe?
by Mike Schwartz 29 Apr '93

29 Apr '93

Hank Nussbacher just sent me figures from the April Internet Hunt results, indicating that Switzerland, Denmark and Finland each sent more data into the NSF backbone than they retrieved from it. The figures weren't broken down by service, but I suspect this is because of FTP. If any network admins in Europe have more information on this, I would be interested in hearing. It sounds like an ideal opportunity to cache FTP traffic. FYI, Peter Danzig, Rick Hall, and I recently completed a study about FTP caching, showing that reasonable sized caches placed at network entry points could reduce FTP traffic by 42%. The paper is available by anonymous FTP from ftp.cs.colorado.edu in the directory pub/cs/techreports/schwartz/PostScript/FTP.Caching (compressed PostScript) or in the file pub/cs/techreports/schwartz/ASCII/FTP.Caching.txt.Z (compressed ASCII). - Mike Schwartz Univ. of Colorado - Boulder

It's sort of "common knowledge" that the traffic out of Finland is always a lot more than traffic to Finland, and indeed this is due to the ftp archives they have there. So I would say that we do have an excellent cache in Europe (Finland). How about NSF doing some caching, so people from over there didn't have to pick up everything from Finland ? :-) -------- Bjorn Eriksen SUNET/NORDUnet Operation Center, KTH, S-100 44 Stockholm Phone: +46 8 7906513 Fax: +46 8 241179 ber(a)sunet.se /S=ber/PRMD=sunet/ADMD=sunet/C=se/

Technically, they would not be considered hosts that are directly on the Internet. Some pings are probably lost due to links being down, and/or problems with the pinging process.

The house has a rich history, dating from 1671, and is furnished in the original style of the time. The master painter Ferdinand Bol was the first occupant, and later it was occupied by the van Loon family, who still live in part of the house today. The largest part however, is used as a museum. Before the dinner there will be a guided tour of the house, which is situated in the heart of Amsterdam on one of the most beautiful canals.

Comments are of course very willcomme. A final version should be distributed at the Trondheim conference in May. o progress in ECE network initiative o GISS specs and implications for the connectivity WG o international links usage and previsible evolutions in ECE countries I ask RIPE attendants from ECE countries to prepare some figures and a short overview about this (I do it for CZ,SK) o cheap IP connectivity solutions based on UNIX router platforms Daniel Kalchev has proposed to expose this topic at the last meeting o mbone in ECE countries - fiction or reality ? several attempts have been realized to audiocast to or from poorely connected coutries - experience + future o further discussion of Russia connectivity if needed all issues will probably not be solved during the plenary (technical and organizational details can be postponed here) o AOB CEEC forum in Trondheim .... Duration - probably two 1.5 hrs slots depending on further input.

Audiocast of the 15th RIPE Meeting
by Daniel Karrenberg 16 Apr '93

16 Apr '93

For the upcoming RIPE meeting we plan an audiocast again. This time this will be slightly more reliable than the last attempts! We have had time to prepare the proper equiment on site so that the analog audio feed will be of high quality. In fact we have just rigged the PA in the meeting room, so we know it is going to work. Also the network Internet bandwidth available at the meeting site is expected to be sufficient. The SARA EBS and EUnet central nodes are both in the same building. We were very much tempted to try video as well but there is not enough bandwidth for that. There will be one channel of GSM encoded audio only. The session will be advertised in sd as "15th RIPE Meeting Amsterdam". If there is anyone not able to use sd, please contact us. The approximate shedule is: April 27th 1400 to 1800 plenary April 28th 0900 to 1800 "biggest" working group session, if the working group using the main auditorium agrees. April 29th 0900 to 1600 plenary The definite shedule will be posted as soon as it becomes more clear. Times are Central European Time (UTC+2). We do not plan time shift reruns since we estimate this is interesting mainly to a European audience. Qestions from the net: We will not have audio piped into the room. If you would like to ask a question or give us feedback please use "talk(1)" to question(a)audio.ripe.net. Testing ------- We will be running tests during next week 19-25 April. Fortunately there is a HEP meeting shelduled in the same auditorium during this week. They have kindly agreed to be audiocast both as a test for the upcoming RIPE meeting ad as a test within their own community. The meeting is called HEPMiX and is about HEP computing using Unix as well as VM. More information about that meeting can be found in ftp.nikhef.nl:pub/hepmix. During Friday we will broadcast periodic test announcements. You should thus be able to test your connectivity the whole week before the RIPE meeting.

Re: FYI - RARE ATM Pilot preparation
by Dennis Jennings 16 Apr '93

16 Apr '93

I read with interest the note on the proposed ATM Pilot. You may be interested to learn that Interop has established a company in Paris - called Interop Europe - and they will be running the first INTEROP Eruope week in October this year. Among the many events taking places are: 1. A two day graduate level tutorial on ATM to be given by Martin de Prycker. 2. A number of sessions in the Interop Conference on ATM in the LAN and WAN. 3. A Solution Showcase demonstration of ATM technologies interworking between LAN and WAN products - approximately 20 companies have already signed up. 4. A wide range of equipment and demonstrations in the Interop Exhibition. As you know, Interop in the US has strong ties into the research community - indeed, Dan Lynch, President of Interop, is on the IAB. Interop Europe hopes to develop similar strong ties to the European research community, and has already sponsored a number of activities and events.

FYI - RARE ATM Pilot preparation
by Milan Sterba 08 Apr '93

08 Apr '93

The last RARE RTC meeting has encouraged Piet Bovenga to go on in preparation work for a more broadly based ATM pilot. The pilot of course also includes the idea of running IP over ATM. That's why I forward his mail to this list, thinking that some RIPE colleagues could be interested in joining. Regards Milan Sterba --- Forwarded mail from Piet Bovenga <P.Bovenga(a)uci.kun.nl> Date: Wed, 07 Apr 93 12:52:05 MET From: Piet Bovenga <P.Bovenga(a)uci.kun.nl> Subject: ATM proposal To: tf-atm(a)rare.nl Cc: wg-llt(a)rare.nl, rtc(a)rare.nl Message-Id: <01GWQBDWRUV48WXK63(a)KUNRC1.URC.KUN.NL> X-Envelope-To: rtc(a)RARE.NL, tf-atm(a)RARE.NL, wg-llt(a)RARE.NL Sender: rtc-request(a)rare.nl X-Charset: CP852 X-Char-Esc: 29 Status: O To all ATM interested people, As already announced in an earlier message I should start writing an ATM-pilot proposal arround 1st of April. In the meantime such a first draft has been written. You find the proposal appended to this message. The writing of this proposal has been speeded up as I have been encouraged by the RTC to produce a "first shot" before yesterday's RTC meeting by telephone. RTC concluded that WG-LLT should proceed in the direction indicated in this draft proposal recognising that besides the technical aspects, to discuss in WG-LLT, there are financial issues and politics to be solved. Based on the above specific the ATM-people are kindly requested to send in to the TF-ATM list any comments and additions you feel fit to make the proposal the best we can get. You are invited to send your comment before 20 April to produce timely a final draft to discuss during the WG-LLT meeting in Trondheim. Specific questions regard more detailed information on standards and products to add to the proposal. Also organisations interested in pilot-participation are kindly requested to expres their willingness to contribute actively. Just to mention : it's version 0.0. indicating that it's the very first draft open for any comment that may arise. Kind regards, Piet. ============================================================================ DRAFT DRAFT DRAFT DRAFT DRAFT DRAFT DRAFT DRAFT Proposal for a Pan-European RARE - ATM pilot ============================================ version 0.0 : 2 April 1993 author : Piet Bovenga 1. Introduction ------------ This proposal aims for the set-up of a Pan-European cooperation between organi- sations directly involved in WAN and LAN based pilots and early services for which ATM technology in combination with PDH and/or SDH transmission technology will be used. At the moment it can be noticed that at different places in the Academic and Research community the application of ATM technology gains strong growing interest. This is demonstrated by the overview of pilots which already have been started up or are in preparation to start in 1993/94 (see annex 1). Within RARE the WG-LLT is assigned to study high speed lower layers technolo- gies and put forward proposals to make those technologies available for the RARE usercommunity. In the workplan 1992/93 the RTC decided that WG-LLT should produce a study of implications of adoption of ATM, Frame Relay and similar new technologies into existing networks with particular relation to routing and addressing issues. A first step to achieve this goal has been to set up an electronic task force TF-ATM(a)rare.nl aiming for communication among experts and information for non-experts in the area of ATM technology (see annex 2). At the moment this electronic task force has a membership of 31 people. Via the list information has been gathered on ATM-pilot activities as laid down in annex 1. Now it seems the right moment to start up a RARE ATM-pilot activity offering an experimental ATM-service with Pan European coverage for the R & D community. This proposal aims for the setting up of such a pilot activity describing: -- Why an ATM-pilot ? -- Aim and scope of the pilot-activty. -- Standardisation status. -- Product availability. -- Pilot proposal. -- Funding needed. -- Document references. 2. Why an ATM-pilot ? ------------------ This proposal to set up a RARE ATM-pilot activity is based on the following observations made : a. Information technology is developing dramatically fast in the area of High Performance Computing. The HPCN-report [1] identifies three broad classes of applications in the field of HPCN : -- Simulation and design in engineering and science; -- Information management; -- Embedded system applications. Network facilities should be in pace with the growing demands on speed, performance and reliability required by the applications to be used in HPC. b. New network services are currently under development for which high speed communication facilities are needed. A second aspect is the integration of video, voice and data services through which a.o. video conferencing and multi-media applications can be made available. ATM can offer a common carrier service over SDH transmission facilities suited to meet the requirements on the lowest lower layers. c. Annex 1 gives an overview of ATM-pilots already running or in preparation on several locations in Europe. This shows a wide spread interest in testing ATM-technology for WAN as well for LAN environments. However these pilots are (partly) bottom up approaches initiated independently from each other. From an European perspective those pilots can be considered as ATM "islands" A RARE pilot initiative in this field can enhance significantly the European initiatives sofar by offering ATM interconnection facilities. It also brings people from different sites together. d. The big amount of publications in which ATM is mentioned shows a worldwide strong interest in this technology. These publications cover tutorial material as well as product announcements from a wide variety of suppliers. In general it is expected that starting in 1993 there will be a range of commercial available products in the market place from 1994 on. e. Within RARE it was already emphasised in 1991 that ATM is a very promising technology for the R & D community. This was expressed in the EEPG-report [2] approved by RARE/COA in May 1991. 3. Aim and scope of the pilot activity. ------------------------------------ The aim is to set up an experimental Pan-European ATM-service which can be accessed by interested parties within the R & D community to offer a high speed transport facility to serve transmission of voice, video and data as well as any combination of these services to be used for video conferencing and/or multi media applications. The pilot should gain experience with ATM- technology for real live applications testing networkperformance (througput, reliability, error rate etc.) and service availability. The scope of the pilot includes layer 2 services as offered by the ATM Adaptation Layer (AAL) supported by the ATM layer over SDH, where applicable, or PDH. Initially transmissionspeeds to choose from are 34 Mbit/s (PDH) and and 155 Mbit/s (SDH) depending on the needs of the applications during the pilot period and the transmission facilities that can be made available not excluding the possibility to test with speeds of 622 Mbit/s. Line speeds of 2,5 Gbit/s to consider feasible later on in the nineties. Layer 2 services have been classified by the CCITT in the classes A through D. Derived from that 3 AAL-types were defined from which 2 are relevant for the intended pilot: -- AAL type 1 to be used for circuit emulation in bit stream oriented appli- cations like video and voice. -- AAL type 5 to be used for IP data traffic over ATM. It's up to the organisations, participating in the pilot, to choose from the offered layer 2 services to mount IP, CLNP, FR, SMDS extensions on. The pilot objective is to demonstrate the feasibility of ATM-technology on an European scale to be used for high speed datatransmission, voice and video as well as for any combination of these services like to be used for multi-media applications and video conferencing. 3. Standardisation status. ----------------------- To assure "open" interworking in the Pan European pilot between equipment under control of different organisations and from different supplier origin the equipment used in the pilot should conform to the I-series of standards being formulated by the CCITT for Broadband ISDN (B-ISDN). The following standards apply: I.121 : Broadband aspects of ISDN. I.113 : Vocabulary of terms for broadband aspects of ISDN. I.432 : B-ISDN user-network interface - physical layer specification. I.150 : B-ISDN asynchronous transfer mode functional characteristics. I.211 : General service aspects of B-ISDN. I.311 : B-ISDN general network aspects. I.321 : B-ISDN protocol reference model and its application. I.327 : B-ISDN functional architecture. I.361 : B-ISDN ATM layer specification. I.371 : Traffic control and congestion control in B-ISDN. I.413 : B-ISDN user-network interface reference description of UNI. I.362 : B-ISDN ATM adaptation layer (AAL) functional description. I.363 : B-ISDN ATM adaptation layer (AAL) specification. Q.93B : B-ISDN user-network interface layer 3 specification for basic call/ bearer control. I.610 : B-ISDN operations and maintenance principles and management. H.261 : CBR-based video at 2 Mbit/s: required service. N.B.: This list of standards needs to be refined an checked against today's actual situation by experts. 4. Product availability. --------------------- A survey carried out in 1992 by the SuperJANET ATM Technical Advisory Group (SJATAG) shows the following list of ATM switch suppliers who claim to have ATM switches or give expected shipping dates or detailed information on their products under development : Alcatel / AT&T / Ungermann Bass / DSC Communications / Fore / Fujitsu / MPR / Adaptive / Netcomm / NEC America / Newbridge / Northern Telecom / Stratacom / Synoptics / TRW. Also under the auspice of SJATAG a survey among suppliers was carried out to gather information on ATM-interfaces for routers. This survey has been fina- lised in February 1993 and resulted in the following list of suppliers who claim to have existing products for ATM interfaces on routers or detailed development plans for such products : 3COM / CISCO / Hughes LAN Systems / Network Systems / Ungermann Bass. The above surveys shows a broad interest among suppliers for offering ATM products. It may be expected that in 1994 there will be a whole range of commercial available ATM products from different suppliers. 5. Pilot proposal. --------------- With reference to point 3 of this proposal the aim is to set up an experimental Pan-European ATM service offering high speed access to interested parties within the R & D community. The objective is to demonstrate the feasibility of ATM-technology on an European scale. The pilot should therefore act as a testbed for the services mentioned under point 3. After succesfull operation there should be a transition to operational services. The time frame for the pilot is considered to last from mid 1993 until the end of 1994. The pilot is open for participation by any organisation within the R & D community if they wish to participate. Collaboration with interested suppliers of ATM equipment is welcomed. Based on the above the following steps should be taken : 1. Inventarise which organisations within the R & D community show interest in active participation in the pilot. 2. Set up of a small Task Force responsable for the coordination, planning and control of the pilot progress and capable to handle all the technical issues that come up. Membership of the Task Force should be recruited from the initial active participating organisations. 3. Design of a network topology to be used as testbed and detailed planning of equipment and connections needed including an estimate of the costs involved. It should be noted here that the startup topology will be strongly influenced by the initial participation in the pilot. 4. Set up the infrastructure according the topology as decided on in step 3 and test connectivity and interoperability between connected ATM equipment based on a testplan. 5. Set up of an application testplan subsequently demonstrating the pilot set up as a testbed to show the capabilities of the ATM infrastructure. 6. Report on the pilot results during the pilot and to publish a final report at the end of the pilot period. N.B.1. : The above is a global description of the activities to be undertaken. Refinement is needed by the Task Force to get a detailed estimate of material, money and time involved. N.B.2. : The Task Force should meet on a regular basis. Synchronisation of TF meetings with major networkevents (JENC, IETF, NSC, etc.) should be sought to minimise the costs for travel and allowance. If a final decission on the pilot is taken during the JENC in Trondheim a first TF-meeting can take place during the IETF-week in Amsterdam. N.B.3. : The already existing distributionlist TF-ATM(a)rare.nl can be used for information exchange between pilot participants and knowledge disse- mination to interested people not participating in the pilot. 6. Funding needed. --------------- As already indicated a realistic estimate of the total costs involved is difficult to give at this moment in time. Splitting up the cost elements gives the following catagorisation : a. Material costs for connections and extra equipment. b. Manpower to spend by the participating organisations to carry out all the activities to run the pilot. c. Travel and allowance costs for members of the Task Force in case meetings outside major networking events show to be necessary. d. Manpower involved producing interim reports and the final report including recommendations how to continue the ATM-pilot service as an operational service. These recommendations ask for close cooperation with the RARE Operational Unit. Funding should be sought for the cost catagories a, c and d. It is assumed that the participating organisations carry the costs ad b. 7.
