[Nsi-wg] Question about NSA identifier

[Jeroen van der Ham]

Hi,

From a topology point of view I don't see any restrictions.

Can someone please explain to me again why we need a one-to-one mapping between NSA (NSA identifier) and Network (Network Identifier)?  It seems to be a very arbitrary restriction.

In addition, the topology schema could easily have multiple "managing" elements within the NSA object to allow it to reference multiple Network Identifiers, thereby creating a one-to-many relationship.

For example, off of one NSA (urn:ogf:network:surfnet.nl:2012:nsa) we can support the ETS service (urn:ogf:network:surfnet.nl:2012:ets) and an EPL service (urn:ogf:network:surfnet.nl:2012:epl).  At the moment, given the current restriction, I would have to have two separate NSA.
