Re: [Teas-ns-dt] Comment to definitions draft in today's call -- logical vs abstract vs virtual

["Belotti, Sergio (Nokia - IT/Vimercate)" <[e-mail]>]

I think that logical (or even abstract) is more comprehensive since virtual reminds to some kind of virtualization of the underlying resources, but a slice could naturally involve (dedicated) physical resources. So that is why I'm inclined to use logical as a more generic term.

Virtualization has nothing to do with "select" only physical resources but instead is related to select underlying resources (physical or abstract) in the prospective to a particular customer, application or service.
If this was your problem with virtual , it is not a problem.

Subject: [Teas-ns-dt] Comment to definitions draft in today's call -- logical vs abstract vs virtual

Hi all,

Apologies, I experienced problems in the call today, not being able for me to speak up (even I lost part of the discussions, apologies again).

I wrote my preference in the chat, I think you couldn't echoed.

So respect to the discussion of preference for logical  vs abstract vs virtual, I think that logical (or even abstract) is more comprehensive since virtual reminds to some kind of virtualization of the underlying resources, but a slice could naturally involve (dedicated) physical resources. So that is why I'm inclined to use logical as a more generic term.

Note that in the operators' vocabulary today "virtual" has further connotations (exceeding the transport part), so can be an overloaded term in some end-to-end scenarios.

Best regards

Luis
