The optical plane clearly needs a control plane that provides a (lambda)
routing and signaling infrastructure. This infrastructure is fundamentally
similar to the routing and signaling technology that we're already using
for MPLS. Now, we can choose to re-invent this technology, or we can
leverage the technology that we have already have developed and have
started to deploy.
Note that this argument is completely independent of the nature of the
optical client. Nothing here precludes non-IP usage of the optical core.
It would simply use the IP network as the out-of-band control plane.
