Good morning, Marseille! Fourth day of #RIPE76 with more Working Groups (#IoT, MAT which is measurements, free software wrongly labeled o... s...). https://ripe76.ripe.net/

Unfortunately, I'll be at a meeting of France-IX board, so I'll miss most of them.

RIPE 76 – 14-18 May 2018 | Marseille

Now, MAT working group (Measurements) at #RIPE76."Real Time Monitoring and Troubleshooting of Web Browsing Sessions" by
Antoine Saverimoutou.

Uses #Selenium to drive a Wweb browser and measuring everything.

Analyzing the performance of a Web page is very complicated because each page loads a lot of things, from many different #CDN. (Nice dependency graph)

The tool is available but not yet on a public forge. #RIPE76

"Multi-Gbps HTTP Traffic Analysis in Commodity Hardware Based on Local Knowledge of TCP Streams" by Carlos Vega at #RIPE76

Main goal is speed.

For instance, they don't reassemble TCP connections: they just analyse the first IP packet of the HTTP request and the first IP packet of the HTTP response.

(So, their analysis of URL length stops at 1455 bytes.)

50 times faster than tshark, for instance (yes, the speaker noticed he compares apples and oranges) #Wireshark #RIPE76

"Perceptual Evaluation of Web-Browsing" by
Diego Neves da Hora at #RIPE76 (and I *hate* the word "eyeballs", which reduce users to consumers)

Second time I see the acronym ATF, which I didn't know before #RIPE76

(That's the time it takes to display the visible part of a Web page. ATF <= PLT )

PLT is questionable anyway. Sometimes, you load the entire page, its objects, but asynch. Javascript code did not complete its work yet, so, from the PoV of the user, it is not loaded yet. #measurements #RIPE76

"RIPE NCC Tools" by Robert Kisteleki, a lot about RIPE Atlas of course, including mention of my #blaeu set of tools, and @Keltounet Go tools. #RIPE76
Show threadStéphane BortzmeyerMay 17, 2018
RIPE Atlas probes can now test #DNS over #TLS (API only). #RIPE76 #privacy

Other RIPE measurement tools: #Zonemaster is now the backend in RIPE stat #DNS tests. #RIPE76

Nice vizualisation of end-to-end paths in the network. For France, the actual backbone is #Zayo :-) #RIPE76

"Measuring Routing Insecurity at the Global Scale" by Andrei Robachevski #RIPE76

@bortzmeyer Yeah really nice visualisation! I remember the first versions of the IXP jedi, it's much prettier now :)
