[Nsi-wg] Topology virtualisation

[Erik-Jan Bos]

Hello Gigi:

The way I see this is that a GOLE is policy free, and the policy of the
connectivity crossing a GOLE is the "sum" of the policies of the two
domains interconnecting/crossconnecting.

A link between two GOLEs, such as the IRNC 10G lambda between
NetherLight and StarLight as an example, always has an owner: In this
case the IRNC project's principle investigator, with his/her policy!

Best regards,
