(we submitted this presentation during OARC34, so I'll re-post it here)
So this is a paper that got accepted at the peer-reviewed PAM2021 conference, and it covers the issues of truncation,fragmentation, and timeouts from the point of view of a TLD.
Geoff Houston has been long working on this, but our vantage point is different but complementary to his ad network method. I think the main diff is that Geoff does lots of experiments with pushing the limits of data over UDP; we however analyze real-world data form a TLD.
(in short: we have far better news than him :)
We also address the issue of the flag day.
