this would then mean that you would consider such te links
as part of the internal core domain instance

since lmp allows the exchange of switching capability supported
at the end-points (see lmp sect. 126.96.36.199), the use of method
(described also in gmpls-routing) would deliver you links such
that [PSC, LSC] refers to a link between a packet LSR and an OXC,
we would then assume that this te link inter-connects an edge
with a core node
hope this helps,
