Stéphane Bortzmeyer#RIPEduca starts in less than one hour https://www.ripe.net/support/training/ripe-ncc-educa Today, RIPE Atlas probes!
One last coffee and I stand ready.
Soon to start, #RIPEduca. Expect some live-tooting about RIPE Atlas probes, Internet measurements and etc, if the proprietary bloatware Adobe Connect works.
Now, RIPE Atlas probes and Internet Exchange Points, by Willem Toorop and Emile Aben.
"We will start with the first presentation" #captainObvious
A study of Internet connectivity in Canada
Emile Aben presents "IXP Jedi", a measurement of the actual use of Internet Exchange Points (like the France-IX) through RIPE Atlas measurements. Do they really "keep local traffic local"? [Insert picture of a very smiling user]
A limit of all RIPE Atlas measurements, spotted by Emile Aben: probes vs. Internet users is heavily biased. Not enough probes in Africa, for instance (and "too many" in Europe). #RIPEduca
John Shaft (ジョン・シャフト) ✅@bortzmeyer In Asia too : only 15 probes in mainland China (and 28 in Hong Kong), 1 in Mongolia, 5 or 6 in Cambodia, less than 10 in Vietnam...
Example of #Finland: the most common path between two finlandeses probes is inside the country but not crossing an IXP. A minority goes through an IXP.
Example of #France: some FR-FR paths go through the US (and many go to another of the Five Eyes, such as GB) [Remember that Orange does not peer at a public Exchange Point in France]
