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

Hi Jie,

We should not forgot network dynamics: the number of NRPs won’t be frozen, not the underlay networks themselves (think about network merging and splits that are happening while the above services are still offered to customers).

There is nothing wrong that a deployment starts with a single NRP to address a specific service case and then adjust the tweaking to address other vertical needs (if/when they come).

What actually matters is not whether one can call the whole physical underlay network an NRP, but how introducing the concept of NRP will allow to manage smoothly the dynamics mentioned above.

From a technical standpoint, I don’t think we can impose a minimum # of partitions to start make use of the NRP concept.

Cheers,
Med

Hi Krzysztof and all,

Most of this text looks good to me except the last sentence. "A single NRP with the resources of the entire underlay network" is the same as a network without network resource partition. I think we agreed that an NRP refers to a subset of the underlay network resources (e.g. a subset of the buffer/queueing/scheduling resources), thus it is different from the whole underlay network.

[JD]  A subset can consist of the entire set

[Jie] Maybe this is true in general, while I’m not sure such generalization is helpful in the context of network slicing. Do you consider the whole physical underlay network can be called an NRP?

[JD]  Absolutely

[Jie #2] Fine, then we could also generalize that network slicing is already supported in legacy networks for years☺


That said, an NRP may have the same topology as the underlay network.

IMO we need to keep in mind that resource and topology are two separate attributes of an NRP.

Best regards,
Jie
