I hate these parallel sessions. I also want to follow the GNI meeting.
But I wonder if they really need two slots, especially when there is
also the Friday meeting.

Good points. I think Global Identifiers will be used by the network
engineers to identify lightpaths in case of outages and announcements
of planned work. Idealy, this will be the case for both manual and
dynamic lightpaths. For manual provisioning, the global identifier
can be communicated during the provisioning phase.

For dynamic lightpaths, this is much more difficult, I think. You say
the dynamic provisioning systems use global identifiers. I think these
must be coupled to true unique global identifiers using our urn scheme
(or whatever we decide upon). That's the only way to make sure that
outages and planned work can be handled correctly. So I guess the
provisiong systems need to pass the urn global identifier to each
other and there has to be a way by which the network operators can
query the dynamic provisioning systems for the urn global identifier
of a particular lightpath.

I agree we need to right audience for these discussions. Having the
GNI clash is unfortunate. Do you have contacts with those people?
Would it be possible to squeeze the GNI meeting in the Monday slot
