[Nml-wg] DCN glossary

[John Vollbrecht]

Attached is a DCN glossary which is part of DCN architecture and DCN  
reservation documents.

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]

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

I note that in the glossary some information is assumed, in at least  
some of the definitions.  In particular, a path (perhaps a DCN path)  
must include time/duration and resource.  That is, a Link may carry  
multiple paths at a given time, and may carry different paths  
sequentially.

I am wondering if this or something like it can be incorporated (or  
is incorporated) in NML.
