I see the discussion about path/circuit/link etc. And perhaps what I am
going to say is already said (had problems reading NML e-mails), but
anyway;-)
I like the separation of circuit being the actual implementation, while
path is more abstract.
What concerns me also, does a path include the User domains on both sides?
<I call them the user 'UserDomains' as they can be quite complex and can
even have NNI type signaling, although they might not be part of a
central/aggregated managed segment (by an AggregatedDomain)>
SourceDomain and DestinationDomain start/end the signaling, but the path
continues over other 'AggregatedDomains' towards UserDomains (which can
have links hops in it).
I don't know if this question helps;-) In IDC, I think, the usersdomains
are not part of the path (LIDP/SIDP)... In SF, the UserDomains are part
of the path. But I might be wrong in understanding it.
All the best,
Victor
