WH> I would disagree since you don’t always control the addressing and it is better to have an explicit signaling in the protocol what to expect to happen.


Can you kindly provide an example of another standard IETF protocol that has this feature or something similar.

WH> I am not sure how relevant this is but you can find them in SIP e.g. Let have the discussion on th requirements. We already indicated that the usage of SOCKS is too chatty which is an OOB mechanism we propose. In the scenario’s we have in mind it is better to do this in-band in the protocol to avoid the extra latency.
