We design and deploy an extended OpenFlow-based control plane for elastic optical networks with DDO-OFDM transmission, detailing the network architecture, the two-phase routing and spectrum assignment algorithm, OpenFlow protocol extensions and the experimental validation. Introduction An elastic optical network (EON), which is able to dynamically and(More)
—The Control Orchestration Procotol (COP) abstracts a common set of control plane functions used by an various SDN controllers, allowing the interworking of heterogenous control plane paradigms (i.e., OpenFlow, GMPLS/PCE). COP has been defined using YANG model language and can be transported using RESTconf, which is being incorporated by industry. COP has(More)
We present OpenFlow-enabled dynamic restoration in elastic optical networks, detailing the restoration framework and algorithm, failure isolation mechanism, OpenFlow protocol extensions, and quantitatively presenting the restoration performance via the experimental validation on the Global Environment for Network Innovations (GENI) testbed.
