Re: [Teas] [E] Re: Slicing Framework Open issue #1 : Service != Realization

[Krzysztof Szarkowicz <[e-mail]>]

Hi,

I have only one comment, regarding below:

  the "IETF Network
  Slice" which is the realization of the service in the provider's 
  network achieved by partitioning network resources and by
  applying certain tools and techniques within the network (see
  Section 3.1).

‘Achieved by partitioning network resources’ is some specific relation option, which might (or might not) be used in particular realization (depending how the slice is realized, might be entire network is single partition). Hence, it should rather be omitted here, as it should be agnostic to to the actual realization. Thus, I would change it to:

  the "IETF Network
  Slice" which is the realization of the service in the provider's 
  network achieved by
  applying certain tools and techniques within the network (see
  Section 3.1).


Regards,
Krzysztof
