Unified Control Architecture for Packet and Circuit Networks

Past attempts at unifying the control and management of packet-switched (IP) and circuit-switched (TDM/WDM) networks have been unsuccessful, mainly because such attempts have assumed that the control architecture of the networks cannot be changed. We believe that only architectural changes will enable true network convergence. We reason that if such changes allow both types of switching technologies to be controlled in a common way, it allows the network operator maximum flexibility in using the correct mix of technologies for the services they provide. To that end, we propose a converged architecture and control plane based on Software Defined Networking (SDN) and OpenFlow.
