Re: [I2nsf] What does "not subscribe to the basic tenet of 'reference not replicate'" mean? FW: Request for Comments, Interest and Support in I2NSF Re-Chartering

["Mr. Jaehoon Paul Jeong" <[e-mail]>]

Hi Tom,
I see your point.
A common YANG module approach can be done
after the set of the current five I2NSF YANG I-Ds
are published as RFCs and they are augmented to
accommodate new protocols such as QUIC and HTTP/3.

Linda,
Could you submit the I-Ds of Consumer-Facing Interface and Registration
Interface to the IESG?

We will be able to accommodate Tom's common YANG module approach in the 2nd
phase of our I2NSF WG.

Thanks.

Best Regards,
Paul
