Greetings, TSVWG currently has the document "Transport Options for UDP" ( https://datatracker.ietf.org/doc/html/draft-ietf-tsvwg-udp-options) in Working Group Last Call. It includes a capability to fragment datagrams at the UDP layer rather than the IP layer, and one of the use cases that has been discussed over there is using that capability to transmit large DNS responses without suffering the disadvantages of IP fragmentation or fallback to TCP. But we need a reality check from the subject matter experts over here to help us determine whether this idea is viable. Accordingly, I put together a short (and at this point not very polished) individual draft describing how this might work. Your feedback will be greatly appreciated.
Thanks and regards, Mike Heard ---------- Forwarded message --------- From: <internet-dra...@ietf.org> Date: Sun, Apr 28, 2024 at 12:52 PM Subject: New Version Notification for draft-heard-dnsop-udp-opt-large-dns-responses-00.txt To: C.
