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

Dear Chairs,

I do not know how we come to this conclusion given the below facts
1) Email discussion on January,
http://www.ietf.org/mail-archive/web/sfc/current/msg00966.html, with
many supports of moving forward the  document draft-liu-sfc-use-cases.

2) London discussion as per
http://www.ietf.org/proceedings/89/minutes/minutes-89-sfc , where
several people voice out that we need one document

As for draft-liu-sfc-use-cases, I'd say it is not a simple 'general'
use cases write-up, actually it has already merged with one mobility
use case from Med, and it also describe the use cases from the
abstract point of view, i.e. two angles that try to summarize the
existing activities.

Technically, one use cases document is much better for people both
inside and outside to understand the sfc activities better. The
draft-liu-sfc-use-cases serves this target very well. And many use
cases are basically the same according the chaining logic, why we need
so many...

So based on previous discussion both on the list and f2f meeting,  I
am suggesting that we move forward the general document and consider
other documents in meanwhile as they turn out to be significant.

Many thanks,
