Hi Deborah,

thanks for your comment. Your suggestion to describe the PMS as a functional 
component (and a use case "separate physical unit") is good. I have no command 
of SDN or RFC5623 related terminology yet. I'll have to read a little before I 
start to parse the draft and adapt text.

I'll also adapt 
a path monitoring/s/an MPLS path monitoring

Noone of the author team is a native speaker. Text of teams like ours 
admittedly has a certain tendency to be grammatically challenging. Missing 
clarity should be removed.

Regards, 

Ruediger

Betreff: Deborah Brungard's No Objection on draft-ietf-spring-oam-usecase-09: 
(with COMMENT)


----------------------------------------------------------------------
COMMENT:
----------------------------------------------------------------------

Substantive Comments:
General:
I consider Informational status as appropriate. I found the draft title 
"oam-usecase"
a bit misleading as the document is specifically about a centralized OAM 
system, but the document title is accurate so I'm ok as the draft title will 
not be visible once an RFC. "Framework and use cases" would of been more 
appropriate (to me).

Because of the draft title, I found the document a bit confusing initially as I 
was not sure if "system" was used in the BFD sense e.g. a functional component 
or as hinted at initially, and as Section 4, Fig. 1 shows, a physically 
separate "system". Suggest it would help the reader to more clearly say this in 
the Abstract (the rtgdir reviewer also hinted at this).

I'm not sure why the choice was to specifically specify a physically separate 
system? Why not as a functional component with a use case as being physically 
separate? And considering the document is scoped to a physically separate 
system, there is not much information on what is needed to support a physical 
separation (other AD comments). I'd suggest strongly to do a simple rewording 
to scope as a functional component. SDN architectures are based on functional 
components as everyone has different ideas on the physical location of a 
component and "functional" provides a flexibility. Suggest looking at RFC5623 
on the VNTM component.

Nits:
I found multiple sentences lacked clarity/grammar. Ben noted several. Will 
depend if restructure to not preclude as a functional component. The first 
sentence of the abstract could be improved:
a path monitoring/s/an MPLS path monitoring
