Re: [quicwg/base-drafts] PMTUD (#64)

[ianswett <[e-mail]>]

I think I'd like a 'trust but verify" approach to path MTU.  In an ideal case, QUIC would get the ICMP message and verify that it really could get a non-fragmented packet through with that size.  As long as the size was larger than the chosen handshake size, it would try it.  

Some of what we've discussed(ie: padding the CHLO and SHLO and setting the DF bit) is what the implementation does today, and not including it in the draft was an oversight we really need to fix.

Actually, QUIC's congestion control(and I believe FreeBSD's) operates in bytes, not MSS.  But I agree it's likely the network and host are more efficient with larger packets.

But please do a pull request with what you describe above, because I think you're going in a good direction, and it's just a matter of working out some details, which is easy to do in the comments of a PR.
