  1. New Services from theRIPE NCC Henk Uijterwaal RIPE NCC New Projects Group NANOG-26, Eugene, OR January 3, 2020

  2. Outline • 2 services from the RIPE NCC • Test Traffic Measurements • Routing Information Service • Follow-up on talks at the Winter 2000 meeting

  3. Part 1Test Traffic Measurements

  4. TTM 101 • Project to do performance measurements on the Internet • Delay • Loss • Routing • One way, active, “real” traffic • Inter-provider networks only • Hard for individual provider • Techniques can be used for internal networks though • Scientifically defendable, well defined standards • IETF IPPM, RFC’s: 2330, 2679, 2680, ...

  5. TTM Service Goals • Black box • No configuration by the user • No user access • Guarantees well-defined environment for the measurements • Easy to install, little maintenance • Available to the entire community All you have to do, is to look at the results

  6. Test-box Locations

  7. CDMA Clocks • Independent clock source necessary • Installing a GPS clock is not always easy • Any alternatives to GPS? • CDMA • 3rd generation mobile phone standard • Phones needs a time signal • GPS Sync’ed base stations broadcast time signal • Can this be used for TTM?

  8. CDMA Clocks • Yes! Same accuracy • Praecis CT • “Phone without speaker, mike and keypad” • http://www.endruntechnologies.com • Works everywhere your cell phone works • Simply mount on a wall • $0.02 installation costs

  9. Alarms and near real-time plots • So-far, 6-30 hour delay between collection and plots on the web • All kinds of reasons why this is too slow: • Angry customer • Alarm from the box • … • Interface for this, recent plots, few minutes delay • Public Demo: http://tt01.ripe.net:10259/ • Also gives access to configuration and status information

  10. User Interface

  11. Current Measurements Rate, target, packet size Status Who set this up: TTM Crew You (somebody at your site) They (somebody at the other side) User Interface • Data volume (bits/second)

  12. Daily report

  13. Daily Report (2)

  14. IP-Delay Variations or Jitter • For some applications, the absolute delay does not really matter • However, packets should arrive with constant intervals • Voice over IP • Video on demand • Metric and Plots

  15. Trends • Delay over 6 months  Night Morning Afternoon  Evening • Content provider with new customers • Intended for capacity planning Median Delay April 1 November 1

  16. IPv6 version • IPv6 networks so-far • Tunneled over v4 • Performance monitoring was an afterthought • Several native IPv6 network now operational • Interested in performance measurements from the start • Use existing products: RIPE NCC TTM • Porting • -testing, production version by December

  17. Bandwidth • The next measurement to be added • 2 Parameters: • C: Total Capacity • A: Available Bandwidth • Method based on packet dispersion • Available on the box

  18. Part 2Routing Information Service

  19. RIS 101 • AS1’s NOC gets a user complaint: • “Last night, I could not reach www.x.com.” • AS1’s NOC looks at the current routing tables • “Well, it works now” Router AS2 Router AS5 AS1 www.x.com User AS3 AS4

  20. Motivation • Something is wrong with your routing • Current tools: • Log in to your router • Use a looking glass on other routers • Problems: • How to find right looking glass? • What if the looking glass cannot be reached either? • Accessing multiple LG’s takes a lot of time • No history mechanism • Solution: Routing Information Service (RIS)

  21. Goals of the RIS • Set up route collectors that collect BGP announcements between AS’s • Time-stamp and store in a data-base • Set up interactive queries to database • Giant looking glass with history • Network reachability from other networks • Provide raw data and statistics • for reality checks, RRCC project • to generate trend analysis • Available to the Community

  22. 9 Route Collectors RIPE NCC LINX AMS-IX SPINX CIXP VIX Netnod MAE-West NSPIXP2 200 peering sessions Route Collectors

  23. Growing by about 250/month in 2002 More and more sites are multi-homed AS’s seen

  24. CDF for the number of peers

  25. Simple queries • AS by time • RIB for an AS at a given time • Announcements since then • Prefix by time • AS in use • Is your AS seen anywhere? • Startup, registration • Plots • Number of updates • Prefix distribution • …

  26. Hyperlinked “Host spots” webpage(Most active prefixes)

  27. “Host spots” webpage(Most active prefixes) (2) Updates during the queried period: Type Prefix Time Peer AS Path A 193.73.204.0/24 2002-10-01 00:00:03 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:00:04 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:00:05 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:00:12 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:02:00 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:02:30 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:02:54 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:03:28 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:06:38 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:06:39 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:06:43 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:07:11 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:07:39 64.211.147.146 3549 701 702 15623 A 193.73.204.0/24 2002-10-01 00:08:00 64.211.147.146 3549 701 702 15623

  28. MartiansThe list you don’t want to be on... • Prefixes not allowed by draft-manning-dsua • Loopback • RFC1918 space • Class D/E-space, … • Usually private addresses leaking into the public space • Daily list with prefixes and origins

  29. BGP Beacons • Prefixes intentionally announced at known times by each route collector • Announced at 0, 4, 8, 12, 16, 20 GMT • Withdrawn at 2, 6, 10, 14, 18, 22 GMT • Prefix 195.80.(224+n).0/24 • N=0…8 for the RRC’s • Part of the RIS AS 12654 • Intended for flapping and dampening studies • Active since 30/9/2002

  30. MyAS • Currently: user has to visit our webpages • Reverse approach: • List AS’s and prefixes • Warn if something happens to them • Prototype RIPE44
