Hello TSVWG and port experts,

We got this 3GPP Liaison Statement last month:
https://datatracker.ietf.org/liaison/1726/

The key paragraphs are:

3GPP understands that it could be possible to assign to 3GPP a port per
transport protocol (UDP, TCP, SCTP, DCCP) that will be used for service port
negotiation/discovery for all the future internal interfaces defined by 3GPP,
avoiding the need for a systematic IANA port assignment for interfaces used
only inside the 3GPP system...

...it is also the 3GPP understanding that this statement cannot
prohibit 3GPP to request in the future a port assignment for a new service
application for which none of the port assignment alternatives would be
applicable.

They would like confirmation, IIUC, that they are not cut off from any
further port assignments.

Any feedback on what I should tell them in response?

Your friendly AD,
Martin
