This article presents a standardized optical network control plane
highlights the challenges and choicesthat need to be addressed in developing the control plane for optical transport networks.The optical control plane isdecomposed into the fundamental processes of neighbour discovery
service discovery
connection control
and topol-ogy/resource discovery. Different network organizations and partitioning result in several different automated provisioning models:softpermanent circuit
the user network interface and peer.This is the foundation of IP-Centric control and managementfor optical transport networks. This article also introduces the new generation of intelligent optical networks byCIENA.It is characterized by large capacity ofoptical switchs
automated topology discovery
port-to-port circuit pro-vision and dynamic distribution of bandwidth
which will greatly improve the Qos of data and circuit.The new genera-tion of intelligent optical networks is the best choice of switching and transport for Backbone and Metro networks.
