[Ibnemo] How to group/reuse definitions

["Bert Wijnen (IETF)" <[e-mail]>]

During the IETF94 Hackaton, we got some discussion on how much
detail we want to allow or need in the Intent Language when
reusing definitions. For example, let us assume that you

- define a router
- define a firewall
- define a loadbalancer
- define a l2 switch
- etc

And that later on you want to define something like a DMZ and
inside that DMZ you want to use the defined router, firewall, l2 switch, etc.

The end-user/customer would want to just express his/her intent to have
an internet connection with a DMZ I guess.

The network administrator of the ISP (operator) needs to then express that the
DMZ consists of let us say a router, a firewall, a l2switch etc.
Do we want/need the network administrator to have to (or to be able to) specify
the details on how these nodes get connected? Or would we rather see that the
Intent Engine generates the proper connections?

I suggest that those who have proto-type implementations express their approach
and that network operators express their wants/needs for such a scenario.
