Re: [sfc] Progression of use case documents in the SFC WG

[Hui Deng <[e-mail]>]

Speaking as a non author of any drafts here, and also voice made during the
F2F meeting.

I am getting lost why IETF needs to document 3GPP components here, they
have already started their work, what we IETF usually do is just refer to
theirs document, this is how standard bodies work together today. Even if
we document here, they maynot agree with the text, are we asking 3GPP to
refer IETF's document about their scenario, that will be weird.

Even during the F2F meeting discussion, I heard from authors of mobility,
he is proposing a general case, ==> check with minutes.

So my recommendation is that one general case would help people to
understand better about technologies and their coherence.

Best regards,

-Hui
