Keith ======================================================= Minutes Test Traffic meeting. RIPE 40, Prague. Chair: keith.godber at energis.com Wed Oct 3 09:00 CEST 2001 Minutes olaf at ripe.net ---------------------------------------------------------------------- A. Administrative B. TTM, status and plans Presentation by Henk. - Update of RIPE NCC personnel status. + Florian Grubers work on site survey using PDA and GPS. - Network update + Service contracts. More action after RIPE 30 + 14 new TT machines since Bologna 5 for evaluation 9 in the chain + Less growth than expected + Status 63 in the field: 42 machines taking data. + new boxes - European Data Grid - 3 ISPs - Research - Glossy - Direct Marketing - Howto for daily operations - Product development. - Hardware + Automatic Connectivity check implemented. + Better rsync scheme + Motorola clocks replaced for Trimble. (Trade possible for EU 800) + 1u testbox prototype available. + GigEth Next kernel upgrade will have support + 48v power Not in 1u will fit in 2 u. investigation continues + multiple NICs in testbox. no fundamental problem to do this. control software needs modification. - Data presentation + WWW Interface on the boxes. Direct access to local data: OS, satellites and packets. available on tt48 (series C) and higher. Older series do not have the CPU - IETF efforts. + 4 implementations of OWD and OWL, RFC 2339 2679 2680 + No interop of measurement devices. Unify packet formats and setup mechanisms. 2 drafts in ippm WG. RIPE NCC will implement drafts. - Analysis Summaries and trends Bandwidth Jitter Performance Scores 2 groups TU-Delft + Performance scores Physical Distance vs transmission speed does not really work TU Delft: Network distance... looks promising + Continue with present efforts Implements Shavitt paper. (ieee infocom 2001) + generate statistical from traceroute + Wisconsin univ - 2002 + expand measurement network + product and service development + kernel update + User training + IETF work + Solve N**2 problem. (over 100 boxes.. to much data) Question: Are most new boxes in EU? A: No 2 US operators and a global network. Q: Connectivity measurements. A: indirect by looking at packet loss. But not implementing RFCs. C. Summaries and Trends by Wilhelm. - Motivation visual representation has it's limits. - Solutions Summarize data using IPPM owd parameters numerical summaries and trend plots. Numbers are presented in plots: median and 2.5 and 97.5 percentile Color coding for daily variations. Trend plots of above data for longer periods. (e.g 3 months) Deployment: summaries are in production. Trend plots need work. D. TTM Bandwith studies. Santcroos and Henk Uijterwaal - Bandwidth Motivation + curiosity and planning IPPM WG charter + still under discussion + define a BCP Requirements + little impact on the normal traffic + exclude HW and SW effects + Real time measurements - Parameters C: bandwidth or capacity A: Available bandwidth C-A: Utilized bandwidth. Start using C. - Available tools RTT tools (pathchar, pchar & clink) Packet Dispersion (pathrate) Protocol dependent tools. (Netperf) - Tools in detail (.. the details...) - Comparison of tools pathrate is best in determining the real cable. pathrate takes a few times longer to converge. - Plans Continue in pathrate Put in testboxes. Discus BCP work in IETF context. Q: Have tests been done with asymmetric links. A: Pathrate is asymmetric. For RTT tools you will not be hurt. Q: How about complicated topology A: No results quite yet. Q: Can you use this for the long distances A: We can do both, for long pathrate is giving best results. E. RIPE TT data analysis at AS level by Jan-Pascal van Best. - Focusing on traceroutes relating to network layout - Background + PhD: Coordination of Internet IP connections How inter ISP agreements affct IP QOS + UMEEPI project - Why ASs + RIPE TT spans 3600 IP addresses 111 ASs ASs reflect routing policy + WHOIS data currently used (Route Views would be better?) + Only 20 IP addresses unmappable - Analysis tools + Traceroutes -> IP Graph -> AS graph + IMport tool Queries TT DB, Whois servers and generate XML + Analysis tool visualizes the network shows evolution in time + Available under GPL - Outlook + theoretical analysis of graphs + use delay measurements + improve graph display mechanism - Demonstration. XML file loaded to generate graph. Inter Testbox ASs can be distinguished from Testbox ASs. Size of AS is indicated. Possibility to select individual ASs and look at connectivity Possibility to zoom into AS and look at time-series within that AS. Impressive graphical tool. F. Jitter Analysis by Reinhard Sojka and Henk Uijterwaal - Motivation + Absolute variation does not really matter variations do. (VoIP) + IPDV metric to measure variations in delay. useful if measurement errors in delay are small compared to variation. + IP Delay Variations also referred to as jitter. - IPPM draft. by Demchelis and Chimento# - Draft implemented + takes into account experimental errors. + plots available + writeup available soon - Demo + interesting cases - Plans + get feedback on write up + add IPDV to daily plots + study interesting cases. H. Direction of group. Chair asked for directions of the group Q: Is netflow work related to the group. A: Yes it is. Note taken. I. Call for agenda items for RIPE 41. preferably early. J. AOB none.

(Anonymous) From henk at ripe.net Tue Oct 16 15:11:35 2001 From: henk at ripe.net (Henk Uijterwaal (RIPE-NCC)) Date: Tue, 16 Oct 2001 15:11:35 +0200 (CEST) Subject: Follow-up on Prague Message-ID: Dear test-box hosts and tt-wg, Here is a bit of follow-up on TTM developments announced at RIPE40 * Web interface =============== As we announced at RIPE 40, we have added a web-interface to the series-C test-boxes (tt48 and higher). This web interface provides immediate and graphical access to the data as it is being collected by the test-box. To access this web-interface, go to http://ttXY.ripe.net:10259 with XY the number of your test-box. Access is restricted to the sites hosting the test-box, if you get an access denied error please contact us (tt-ops at ripe.net) with the IP address of the machine(s) from which you want to access the box. If you click on the "measurements" button, you will be able to see the incoming delays on average 5 minutes after they have been measured. This should allow you to investigate problems with your external connectivity in real time. If you do not have a series C test-box but like to see this feature, you can use one of the machine at the RIPE NCC at: http://tt01.ripe.net:10259 Please let us know if you have suggestions for improving this interface. Note that this interface is NOT available on the older test-boxes due to a lack of resources. If you own an older test-box and are interested in this feature, then we can discuss upgrading the hardware though. * Summary numbers ================= We are now producing a page with summary numbers for all test-boxes. This page is available at: http://www.ripe.net/test-traffic/Plots/ttXY/summary.html with XY the number of your test-box. In order to access this page, you need to use your username/password combination. The page shows the TTM delay & loss parameters for traffic received from and send to the listed test-boxes by your test-box. Each cell lists both the result for the above date as well as (in parentheses) the median value of this parameter for the last 10 days. If the two differ by more than 40% the background of the cell will be colored: red when the parameter increased, green when it decreased. By simply looking at the red squares, you will be able to find the connections that deteriorated over the last 24 hours and might require further investigation. * 1u high test-boxes ==================== We're pleased to announce that we have completed testing a 1u high test-box. This box offers the same functionality as the 4u high model but only takes 25% of the rack space. At the moment, we are working out the final details with the vendor, we expect that we can start to offer this box in a few weeks. If you have any questions about this, please do not hestitate to contact us, Kind regards, Henk ------------------------------------------------------------------------------ Henk Uijterwaal Email: henk.uijterwaal at ripe.net RIPE Network Coordination Centre WWW: http://www.ripe.net/home/henk Singel 258 Phone: +31.20.5354414 1016 AB Amsterdam Fax: +31.20.5354445 The Netherlands Mobile: +31.6.55861746 ------------------------------------------------------------------------------ As long as you don't tell your friends how I played the hand, then I won't tell my friends how you defended it.

This machine offers several advantages over the test-boxes that have previously been installed: * A 1u high cabinet. This means that the machine only takes a quarter of the rack space compared to the old model. * Hardware support for the machines will be transferred to the Dell sales organization in your country, with next business day support at your office. This eliminates the need to send broken test-boxes back to Amsterdam and will increase the uptime of the machine. * 2 Network Interface Cards (NIC's). This will allow you to assign 2 addresses to the machine and connect it to 2 border routers. The test-box can then be used to measure delays and latencies through 2 different upstream providers. For more details about this, please refer to: http://www.ripe.net/test-traffic/Talks/0110_RIPE40_HU/sld015.html These machines offer all features that are currently being offered on the test-boxes, including the WWW interface to the data announced last week. For a full list of features, please see: http://www.ripe.net/test-traffic/Notes/ A public demo of the WWW interface is available at: http://tt01.ripe.net:10259/ The old test-box model will remain test-box will available. This model is recommended for sites that need a 3rd NIC or other special hardware. When in doubt, please contact us at . Test-boxes can be ordered online at: http://www.ripe.net/test-traffic/Host_testbox/host_testbox.html For more information about the TTM service in general, please see: http://www.ripe.net/test-traffic/ For sites interested in upgrading their existing test-boxes, we offer the possibility of a trade-in. If you return a test-box from series A or B (serial numbers tt02 to tt47), we will offer a 400 Euro discount on the new box. For details please email us at ttm at ripe.net.
