Transcript

  • 1. RIPE Atlas!Robert Kisteleki!RIPE NCC Science Group!robert@ripe.net!
  • 2. Introduction"RIPE Atlas:"•  There are many Atlases, this is RIPE Atlas"•  A prototype system for a next generation Internet measurement network" -  To scale to thousands of measurement nodes" -  Potentially “be everywhere” and ready to run different measurements" -  Started last November, we’re still just building it and exploring possibilities" 2!
  • 3. Light Map of Europe" 3!
  • 4. Intuition: 1000 Probes" 4!
  • 5. Intuition: 5000 Probes" 5!
  • 6. Intuition: 10k Probes" 6!
  • 7. Intuition: 20k Probes" 7!
  • 8. Intuition: 50k Probes" 8!
  • 9. Intuition: 10k Probes & 1 AS" 9!
  • 10. Ambitious Community Effort" Instead of building small, separate, individual & private infrastructures, " build a huge common infrastructure" that serves both the private goals " and the community goals. " 10!
  • 11. Ambitious Community Effort"•  Individual Benefits" -  Lessexpensive than rolling your own" -  More vantage points available" -  More data available"•  Community Benefits" -  Unprecedented situational awareness" -  Wealth of data, …" 11!
  • 12. Intuition -> Plan"•  For accurate maps we need more probes"•  Deploying very many TTM boxes too expensive"•  Smaller probes "•  Easily deployable"•  USB powered"•  24 x 365 capable" 12!
  • 13. Probe Deployments" 13!
  • 14. Versions"•  Version 0" -  Ping to fixed targets (IPv4 & IPv6) !" -  Traceroute to 1st two upstream hops !"•  Version 1" -  Ping& Traceroute to variable targets" -  DNS queries to variable targets"•  Version 2" -  Your ideas ?"•  A non-goal: performance measurements" 14!
  • 15. Network extent" 15!
  • 16. Network extent" 16!
  • 17. Network extent" 17!
  • 18. Network extent" 18!
  • 19. Network extent" updated hourly on" 19!
  • 20. Hosting = Credits = Measurements" 20!
  • 21. What you see is what you get" 21!
  • 22. What you see is what you get" 22!
  • 23. Sponsorship = Credits = Measurements" 23!
  • 24. Sponsorship = Credits = Measurements" 24!
  • 25. Sponsorship = Credits = Measurements"•  Most of the early sponsors are more in for the idea than for the potential benefits (for now)"•  Many of them are DNS providers of some kind" •  They have multiple locations" •  … and “renting” measurement functionality is simpler than building a complete measurement network yourself" 25!
  • 26. Measurement nodes – “Probes”"•  Probe (v1 / generation 1):" -  Lantronix XPortPro" -  Very low power usage" -  8MB RAM, 16MB flash" -  Runs uClinux" -  No FPU, no MMU, virtually no UI" -  A reboot costs <15 (<5) seconds" -  An SSH connection costs ~30 seconds" -  We can remotely update the firmware" -  Form factor of the finished probe is “just right”" 26!
  • 27. RIPE Atlas - Overall Architecture" 27!
  • 28. RIPE Atlas - Security aspects"•  Probes have hardwired trust material! (registration server addresses / keys)"•  The probes don’t have any open ports, they only initiate connections" -  This works fine with NATs too"•  Probes don’t listen to local traffic, there are no passive measurements running" -  There’s no snooping around" " "" 28!
  • 29. RIPE Atlas" Scale Continuous End-user 29!
  • 30. Questions?"
