Inter-domain OTN, does it happen in the real world?

[adrian at olddog.co.uk (Adrian Farrel)]

Will, I think you also need to consider the case where one operator runs more
than one network.
This can happen because of acquisition or administrative structure.
I regret it might also happen because of vendor equipment compatibility/lock-in
issues.

Cheers,
Adrian
