OpenFlow Overlay Over the Control Plane (with Abstraction)
With extensions for the control of circuit mapping and packet for-
warding, analogous to what was explored in pac.c and OFELIA,
OpenFlow can be used directly for control over optical switching ele-
ments. To speed up the deployment of such capability in a carrier
environment, which typically consists of multiple domains of deployed
equipment, it would be more cost effective to deploy OpenFlow/SDN
as an overlay rather than introduce an OpenFlow/SDN agent on
every network element and add connectivity from each network el ...
