Re: [Teas] The definition of a Network Slice in draft-nsdt-teas-ietf-network-slice-definition

["Rokui, Reza (Nokia - CA/Ottawa)" <[e-mail]>]

Hi Med and Daniele,

Agreed with Daniele.

The concept of "IETF Network Slice" addresses the connectivity between various network functions, devices and applications with specific SLO/SLA. 
This is the fundamental aspect of "IETF Network Slice" which has been discussed for a while.

Cheers,
Reza

    Hi Med,

    This seems to be re-opening Pandora's box.
    My understanding was that the IETF network slice was the connectivity component of an E2E slice.
    If we're now thinking of the connectivity part of the IETF network slice it means we're "elevating" the IETF network slice to compete with other definitions of E2E network slices.

    I would agree with Jari on the fact that it would be more efficient to focus on what we're good at and focus our effort and energy to get an achievement there instead of trying to cover too many different things.

    Hi Adrian, Jari, all,

    I agree with the observations made by Adrian and Jari's comment.

    It would be helpful to have a name to refer to the connectivity component of an IETF network slice. Also, if there are concrete examples of non-connectivity IETF components that can be cited in the draft, this would be even great.   

    Cheers,
    Med
