Control plane solutions for sliceable bandwidth variable transceivers in Elastic Optical Networks

Elastic Optical Networks (EON) are characterized by a flexible grid in which the so called “frequency slots” are allocated dynamically and based on the client signal data rate and modulation format and rely on bandwidth variable transceivers (BVT) and bandwidth variable cross-connects (OXC). A control plane(CP) is used for the efficient and dynamic provisioning of optical connections with recovery. Such emerging optical technologies bring new requirements to the CP related to the efficient flexible spectrum allocation, co-routed connection setup and dynamic and low latency configuration of optical parameters.
