Amazing debugging, I loved reading that. HN doesn't get enough good posts like this anymore :)

If https://github.com/pion/sctp/issues/12 had happened (not just in Pion but across all implementations) this could have been fixed years ago. The hardcoding we all settle for is tragic.

Author here, thank you, that means a lot coming from you. Pion was the prior art I pointed the webrtc-rs maintainers at. And pion/sctp#12 is super relevant. A known, proposed fix years before we hit it.

"The hardcoding we all settle for" might be the epigraph for the whole incident. webrtc-rs invited a PR for the configurable-MTU + better default half [webrtc-rs/webrtc#806] to unblock folks today. Whether PMTUD gets implemented will be interesting to see.

The debugging was interesting. I'm just going to have to learn to live with this I feel like, but the very LLM-ish language in the blog post was kind of annoying.
