Re: [Teas] Proposed ACTN Definition Text (Re: 答复: Poll on draft-lee-teas-actn-requirements-01 a WG documents)

Hi Young,

I'd add "large-scale" at least in some places where you mention "TE networks". It is the large-scale aspect which points to/ requires new problems to be solved (totally agree with Lou), in particular, the hierarchical abstraction with no limit to the number of hierarchy levels and with both ends (top and bottom) open.

I'd also add:
"Conveying, managing and enforcing client policies with respect to the services provided by the network to said clients"

Regards,
 Igor

NOTE: I've changed the title so that we can keep separate process
discussion from the definition discussion.  Please keep comments limited
to the appropriate thread so folks (like Adrian) that don't care about
the process can ignore it.

 <This is the non-process thread>

This is achieved presenting the network domain as an abstracted topology to the customers via open and programmable interfaces. This allows for the recursion of controllers in a customer-provider relationship.

Great.  This is constructive.  Thank you.

WG,

Please review/comment/propose changes. 

I've dropped the text into an etherpad
(http://etherpad.tools.ietf.org:9000/p/teas-actn-def) to track the
latest text.  Feel free to make changes there if you propose changes.

Lou

> I'm not sure to what you are referring.  The sole formal procedural requirement for issuing a draft is WG chair approval, at which time chairs select the filename.  Now it is certainly normal and good practice for  WG chairs to ensure support for the work via such things as polls, but this isn't procedurally required.  Also, chairs always evaluate the filename as part of our approval process, and while less common,  approve file names different than the form used by the individual draft.  Feel free to look around and you'll find a few examples.
