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!
Light Map of Europe"




                       3!
Intuition: 1000 Probes"




                          4!
Intuition: 5000 Probes"




                          5!
Intuition: 10k Probes"




                         6!
Intuition: 20k Probes"




                         7!
Intuition: 50k Probes"




                         8!
Intuition: 10k Probes & 1 AS"




                                9!
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!
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!
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!
Probe Deployments"




                     13!
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!

Hosting = Credits = Measurements"




                                    20!
What you see is what you get"




                                21!

                                22!
Sponsorship = Credits = Measurements"




                                        23!
Sponsorship = Credits = Measurements"




                                        24!
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!
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!
RIPE Atlas - Overall Architecture"




                                     27!
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"
 " ""

RIPE Atlas

  • 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!
  • 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!
  • 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!
  • 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!
