Introduction"

RIPE Atlas:"

There are many Atlases, this is RIPE Atlas

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"

Ambitious Community Effort"

Instead of building small, separate, individual & private infrastructures, " build a huge common infrastructure " that serves both both the private goals " and and the community goals. "

Ambitious Community Effort"

Individual Benefits"
Less expensive than rolling your own"
More vantage points available"
More data available"
Community Benefits"
Unprecedented situational awareness"
Wealth of data, …"

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"

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"

Sponsorship = Credits = Measurements 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"

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”"

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"
