[Sipping] RE: SBC architectures document

Because there are some works on SBC related functions as specified in
the
http://www.ietf.org/internet-drafts/draft-camarillo-sipping-sbc-funcs-01
.txt, we thought it is a good idea to bring border architecture (or SBC
deployment scenario) at the same time so that you can see the providers'
perspective. The document will help the SIPPING community to understand
that S/BC functions and SIP protocol extensions need to be studied in
holistic 
border protection architecture approach and can be deployed in the
network in scalable fashion. We may need to develop SIP extensions to
communicate between various functional components described in
draft-sohel-sipping-s-bc-concept-arch-00.txt.

Subject: SBC architectures document

Hi,

I read your SBC architecture document and noticed your agenda request.  
I don't immediately understand the relevance of this draft to our 
charter in SIPPING.  We have generally avoided discussion specific 
decomposition approaches in SIP and SIPPING, and frequently we have 
left this decomposition work to other groups, as was the case for media 
servers (speechsc), conferencing (xcon), and media gateways (megaco). 
Is there some specific action that is relevant to the group, for 
example requirements on the SIP protocol?

thanks,
-rohan
