I like to hear from nml-wg participants: - if they think that NML should be capable of defining a topology at different layers of abstraction
Yes but I would make this more general and say - just different layers. They could be abstractions or tech layers (I'm thinking that layers may be also a good solution to control publishing information by configuring somehow that only some layers can be distributed, others not; a single abstraction could be split into more layers because of some reasons; it would be up to the implementation)
Network layers indeed abstract the underlying complexity, but I presume that there is also a need to abstract a single-layer network. Hence, I propose to treat these two as different tasks for now (if we can integrate them later in the same concept, that would be great). I like to spend some time before next OGF to look into VLAN and layer abstraction; if someone else would like to take up the topology abstraction (if only single layer abstraction), that would be awesome.
- how these different descriptions should be tied together. Should we define a relation between them?
I think so. The work on examples will help to progress.
Agreed. I will dot this down as a work item. That can be either one of Jerry's suggested examples, or just some artificial example. Freek
