  • Patent number: 9825811
    Abstract: A network management system (NMS) for a communications network has communications apparatus capable of being operated in different power consumption modes to provide different levels of performance, has a path computation apparatus configured to select paths for the traffic using the communications apparatus, based on information about traffic load in the network and on information about the power consumption modes of the communications apparatus of at least one of the nodes. A power mode controller is also provided for controlling the power consumption modes of the communications apparatus according to information about traffic load and according to information about the paths selected. By combining of path computation and the control of power consumption modes the overall power consumption of the network can be reduced. A slave power mode controller can be provided.
    Type: Grant

  • Patent number: 9806623
    Abstract: A multiple output DC-DC converter comprises a transformer, a primary circuit, a plurality of secondary circuits, and a controller. The transformer has a primary and at least one secondary winding. The primary circuit connects to a DC power supply source and includes the primary winding of the transformer and a primary switch connected in series. The plurality of secondary circuits includes the at least one secondary winding of the transformer, wherein each secondary circuit provides a DC power supply output, and at least one of the secondary circuits has a secondary switch. The controller monitors an output signal of each secondary circuit and controls operation of the primary and secondary switches based on the monitored signals. The controller co-ordinates operation of the secondary switch with the primary switch, such that the primary switch and the secondary switch are switched on simultaneously, or with a controlled offset.
