Re: [Nfvrg] Solicit comments for draft-gu-nfvrg-cloud-bng-architecture-00 "Control and User Plane Separation Architecture of Cloud based BNG"

Hi Rong, 

I had a quick look at the draft, and I have a couple of comments/suggestions. Hopefully they can be of help in a possible revision. 

It's not clear what is the goal and scope of the draft. Is this kind of a dissemination activity for a project you have been involved? Perhaps adding a couple of paragraphs about the motivation for this work may set the stage a bit better. Further, some time ago, the EU FP7 SPARC project (http://www.fp7-sparc.eu/) has looked into BRAS/BNG in a similar context; the deliverables and publications on the site may be of interest to you. In particular, this ComMag paper summarized the overall approach: https://doi.org/10.1109/MCOM.2014.6917416. 

Regarding the draft text, I think it needs some editorial work; here's a few nits: 

s/Clond-based/cloud-based 
s/centralized deployed as/centrally deployed as 
s/router functi on/router function 

p. 4, the sentence "or use of the local" ends abruptly. 

Edge TIC layer: I guess you mean that BNG-UP, not BNG-CP, is "deployed in this layer". 

The ref to RFC 2234 is not actually used. 

Finally, there's a number of acronyms that are not defined on first appearance (e.g. BNG), or not at all (e.g. CSCF, NE). For a short document, I personally find defining the acronyms on first appearance easier to read than providing an acronyms list (sec. 3). 

Just my $0.02. 

Best regards, 

Kostas

Hi, dear all. 

I submit a new draft introducing a control plane (BNG-CP) and user plane (BNG-UP) separation of cloud BNG. In the future network, BNG-UP and BNG-CP are core components for fixed broadband service deployed at different layer. 

For details:

Any comments are welcome. Or if you are interested in that, feel free to contact me. 

Best regards.

Abstract: 
This document defines the architecture of Clond-based BNG devices 
with control plane (CP) and user plane (UP) seperation. Both BNG-CP 
and BNG-UP are core components for fixed broadband services and 
deployed seperately at different network layer. 

Please note that it may take a couple of minutes from the time of submission 
until the htmlized version and diff are available at tools.ietf.org.
