Hi Martin, the main issue Ekr is bringing up is that the DTLS handshake happens infrequently and it is small in size. The use of DTLS for protecting application traffic is not impacted by this timeout.

To reiterate, I believe introducing latency regressions with respect to DTLS 1.2 would be bad for the internet. So what's new in the area under discussion is (a) lowering the timeout from 1s to 100ms, and (b) the introduction of ACKs. I would characterize ekr's reply as making the following points: (1) *DTLS practice at Mozilla and elsewhere already uses timeouts << 1 sec* IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
