Subject: [lmap] Inter-domain scenarios

Hi all,

there are a couple of inter-domain scenarios that I consider interesting:

1) Measurements between devices managed by different organizations
2) An agreement between two organizations for the exchange of measurement requests/data (f.i. at the "controller level" if the controllers are able to talk to each other; this could be useful also in case a single domain has multiple controllers for scalability)

With regard to inter-domain, the current I-Ds show different points of view:

- draft-boucadair-lmap-considerations seems to not exclude at least the first scenario
- draft-eardley-lmap-framework seems to exclude both cases ("...the expectation is that inter-organization coordination is an out-of-band consideration")
- draft-linsner-lmap-use-cases seems to consider some inter-domain aspects ("An operator may also want to monitor the performance of its suppliers, to check whether they meet their SLA or to compare two suppliers if it is dual-sourcing. This could include its transit operator, CDNs, peering, video source, local network provider")

In my opinion the LMAP architecture and protocols should be (at least) flexible enough to not preclude the possibility to add these inter-domain scenarios in the future.

Regards,
Alessandro
