[Nsi-wg] Topology virtualisation

[Gigi Karmous-Edwards]

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
