Abstract: Systems and methods for monitoring an Optical Multiplex Section of a communication network are provided. A method, according to one implementation, includes the step of obtaining parameters related to optical signals traversing an Optical Multiplex Section (OMS) of a communication network. The OMS, in this example, includes multiple fiber spans defining a primary path and one or more protection paths. The method further includes the step of using the obtained parameters to determine a Signal-to-Noise Ratio (SNR) value associated with optical signals transmitted over the primary path. In response to determining that the SNR value falls below a predetermined threshold, the method includes the step of performing a switching action to enable transmission of optical signals over one of the one or more protection paths.

Abstract: Driving an optical modulator is described. A control circuit generates first and second target voltages based on a target phase modulation between first and second optical waveguide arms of the optical modulator. An offset control circuit generates first and second offset signals. A linear modulator driver receives the first and second target voltages and the first and second offset signals, and generates a first output voltage for biasing the first optical waveguide arm and a second output voltage for biasing the second optical waveguide arm. Feedback circuitry can feed the first and second output voltages to the offset control circuit, which can generate the first and second offset signals using the first and second output voltages. The output voltages bias the waveguide arms so the optical modulator operates close to the target phase modulation, even in the presence of manufacturing errors.

Abstract: Systems and methods are provided for predicting how tasks should be allocated to available network resources. A method, according to one implementation, includes the step of receiving resource utilization metrics from each of a plurality of nodes arranged in a cluster, wherein the resource utilization metrics of each node include information related to utilization of one or more resources of the respective node over a plurality of time periods. The method also includes the step of predicting current and forthcoming resource availability of each node based on patterns of resource utilization over past and current time periods. In response to receiving a job request having multiple workload responsibilities, the method includes the step of allocating the workload responsibilities to one or more nodes based on the predicted current and forthcoming resource availability of each node in order to fulfill the job request.
