True, it is a domain. However, if a GOLE has the property of being "open
policy" and its main service is to interconnect paths between GOLEs and
domains, then from a "strictly" path computation perspective, and if
given a choice between a transient link across a domain w/ policy or
through an open policy GOLE, then it seems that the path computation
entity will find it simpler to choose the the path through the GOLE
rather than the domain. What are your thoughts on this particular
scenario...
I can see a situation where an end user may choose to go through a
particular domain if they are members of a domain and have certain
privileges.
thanks,
Gigi
