A WDM Network Controller With Real-Time Updates of the Physical Layer Abstraction

This paper describes the implementation of a wavelength division multiplexing network controller that accounts for the varying conditions of the network physical layer in real time. A newly added software module is used to estimate the physical layer quality of transmission (QoT-E) in the form of a...
