Re: [Teas] terminology discussion network slicing

["Adrian Farrel" <[e-mail]>]

I think a solution here might be to prefix Young's text with the words "In the
context of ACTN,"

That is, we can see that given the current scope and capabilities of ACTN, the
architecture can deliver a set of netslicing features that Young describes.
Whether this is the whole spread of netslicing or not need not be a debate for
an ACTN document. Indeed, I would suggest that having that discussion in an ACTN
document is neither a good idea nor likely to be productive.

Let the ACTN document describe what ACTN can do. Let other documents define what
netslicing is.

Cheers,
Adrian
