Re: [Teas] Decision point on scope of draft-ietf-teas-ietf-network-slices

Hi Igor,

(adding CCAMP as this is becoming a cross-wg discussion)

I get your point but it doesn’t seem fair to me to limit network slicing to 5G just to deprecate slicing at other layers. If there are other technical reasons to do so (some of which you already brought up) that’s fine, but I don’t think we should limit network slicing to 5G.
Moreover I’ve seen quite a lot of support in TEAS not to limit network slicing to 5G (obviously not my call).

Cheers,
Daniele

Daniele,

We all agreed that OTN  does not bring anything new into 5G that, for example,  was not happening  in 4G. OTN slicing work is motivated in some way, at least, because NS framework stipulates that the framework  is not limited to 5G. In fact, it seems to be not limited to anything (application -wise or layering -wise) to a point that it is not really clear what could not be considered a network slice.

However,  If the framework was focused on 5G (ideallt going even further and stating  that said 5G style network slicing happenning in IP layer only, which I believe is the case) ,  OTn slicing would have nothing to do with the framework (and the term  slicing) and would have to rely on its own merits ( which,  as you mentioned, you have doubts about yourself) and also  explain why it coincides in time with NS work triggered and inspired entirely by 5G.

Cheers,
Igor
