Do you have the latest schema? I would like to understand how this all fits together. I have some questions about how multiple circuits can be carried over a Link. And how multiple paths can be carried over a sequence of links. Perhaps I can ask questions better after looking at the schema. John On Jul 1, 2008, at 8:24 AM, Jeroen van der Ham wrote:

Of particular note are some terms we use that don't seem to be in the NML schema (perhaps I am wrong?)
path - a connection between a source and destination. A path is a sequence of hops. source - starting point of path - as defined by direction of signalling destination - end point of path- as defined by direction of signalling hop - a network element - [domain or node or port or link]
These are all in the NML schema as proposed so far. We have Path and NetworkElement objects. And I think the Source and Destination could be encoded as SourceDomain and DestinationDomain. The *Domains part has not been defined completely yet. But I think we can take Victors' presentation as a startingpoint for that?
path segment - subset of a path consisting of two or more hops circuit - a connection between tow endpoints that can be used to transmit data between them
In the discussion in Berlin it was also suggested that we use the term "Path" also for path segments. Whether the path is complete can then be checked by the using Source- and DestinationDomain.
As for the circuit, I think that that is something for a later schema, as it would require descriptions of layers. (otherwise you cannot determine whether you can transmit data over it).
