Hello John and Freek,

The rest of topology I am not sure about.  I would think it a good thing, but I also think it would take a lot of work and be hard to maintain.  Is this what you mean?

In some way I like the idea we had in AutoBAHN: an abstracted topology to determine the path. An abstracted topology does not hold much detail just enough to determine the possible path (I am see this as with human: when they talk about a project they more or less have the physical connectivity in their had.
The next step is are higher network protocol levels compatible.
This is the very first part of path finding (the net graph, which can be in one or two stages).
And than can we make them work (Stitching Framework).
And then implement it (Signaling).

So A full topology is not needed in my humble opinion, but an abstract (at least see a domain as a node).

All the best,
