This document discusses tools and prototypes for visualizing and analyzing Internet routing data based on measurements from RIPE Atlas probes. It describes the IXP Country Jedi tool, which analyzes whether traceroutes pass through internet exchange points (IXPs), and recommends ways to optimize routing. It also introduces Observable notebooks for rapidly prototyping new visualizations of RIPE Atlas data, such as maps of probe neighborhoods and latency. Feedback is sought on using these open tools to evaluate routing and peering arrangements.

4. IXP Country Jedi
(prototype)
jedi.ripe.net

5. • Launched ~2015
• Tool and concept by Emile Aben
- https://labs.ripe.net/Members/emileaben/measuring-ixps-with-ripe-atlas
• Method:
- Traceroute mesh between RIPE Atlas probes
- Detect whether they go via the IXP Peering LAN (data from PeeringDB)
- Hops geolocated using RIPE IPmap database
• Data:
- https://www.ripe.net/analyse/internet-measurements/ixp-country-jedi

About IXP Country Jedi

6. • Benefits:
- Shows how IXPs help keep traffic local
- Comparing countries’ performances with each other
- Routing and traffic optimisation
- Comparing IPv6 and IPv4
• Spain:

About IXP Country Jedi

7. • Different visualisations
• Based on the same
underlying data
• Traceroutes launched from
the probes in a country to the
same set of probes
- Mesh measurement
- Ran once a month by the RIPE
NCC, hosted on jedi.ripe.net

Traceroutes on a map, with geolocation data coming from RIPE IPmap

through an IXP?
- Peering LAN info coming from
PeeringDB
• Do traceroutes exit a
country?
- Geolocation data coming from
RIPE IPmap

10. • Interactive tool! (hover over the
cell…)
• Brown: the path is going out of
country
- If this is a surprise, talk to your
upstream(s) and/or make new peering
agreements
• Dark brown: the path is going
out country although there is a
local IXP in the path
- we do not see this often

14. • Use this tool to optimise your routing!
- … select the path that is going out of country
- talk to your upstream(s)
- … select the path that is not going via a local IXP
- make a new peering agreement
• Contribute to the FLOSS code on GitHub
• If your ASN is not on the graph, apply for a RIPE Atlas probe or
anchor
