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

It is interesting watching the debate on logical, abstract, virtual (and no
doubt, aggregate) constructs.

 

I hope everyone has been reading the work of the TEAS working group
carefully so that we don’t come up with terminology or definitions that is
at odds with previous usages.

 

It is not that we have to agree with previous terms or definitions, but if
we want new definitions it would be wise to use new terms so that we avoid
confusion.

 

You may find RFC 7926 helpful. Especially sections 1.1 and 4.2

 

Enjoy,

Adrian

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.

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
