The RIPE Atlas team released a new online tool that helps to make sense of trace routes that are generated by RIPE Atlas. Use this tool to optimize your routing and debug network problems.

14. Probes in Africa
and how to use them

15. Jasper den Hertog | 30 May 2017 | AIS2017
..that’s why we need participation

IXP Country Jedi
• Tool and concept by Emile Aben
- https://github.com/emileaben/ixp-country-jedi
- https://labs.ripe.net/Members/emileaben/measuring-ixps-
with-ripe-atlas
• Method:
- Traceroute mesh between RIPE Atlas probes
- Detect whether they go via local IXP(s)’ LAN IP
- Hops geolocated using OpenIPMap database
• Data:
- http://sg-pub.ripe.net/emile/ixp-country-jedi/

20. Jasper den Hertog | 30 May 2017 | AIS2017
IXP Country Jedi
• Benefits:
- Shows how IXPs help keep traffic local
- Comparing countries’ performances with each other
- Routing and traffic optimisation
- Comparing IPv6 and IPv4
• Kenya:

the new tool finally

Daily Struggles: A reaches B
• How?
- Optimised?
- IXP?
- Which Autonomous Systems?
- Latency?
•Where?
- Which local entity/node of the CDN?
- From which source?
- Is it going in another country?

25. Jasper den Hertog | 30 may 2017 | AIS2017
Daily Struggles: A doesn’t reach B
• Where does it stop?
- Which AS?
- Which geographical location?
• Who is involved?
- Which portion of the network?
- Who is behind a private address or a ✱ in my traceroute?
- Who can I contact?
• What happens at the BGP level?

26. Jasper den Hertog | 30 may 2017 | AIS2017
Let’s use Traceroutes
• RIPE Atlas multi-source
traceroutes
• What about a viz?
- Complex model
- What is a node? (a single one!)
- Filtering/simplification needed (difficult!)
- Complex view
- Precomputing from Traceroute to Graph (no
operators are willing to do it… daily)
- Static snapshot..still a lot of work and not so
useful Static snapshot (only a portion at a
time, no evolution, complex to follow

27. Jasper den Hertog | 30 may 2017 | AIS2017
What’s new: TraceMON
• TraceMON is a web application for
visualising (multi-source) traceroutes
• Infers network topology and
characteristics of the various network
component involved
• Aggregates data from many data
sources, providing a one-click access to
- Resource holder contacts, latency, whois, BGP
visibility, IP geolocation, IXP detection, reverse DNS
lookup …
