  • JOINT SIGNAL-ROUTING AND POWER-CONTROL FOR AN OPTICAL NETWORK
    Publication number: 20160219350
    Abstract: We disclose a signal-routing method directed at improving the throughput of an optical network by taking into account the fiber nonlinearity in the process of solving a joint signal-routing and power-control problem for the optical network. Based on the obtained solution, a network controller may set the signal-routing configurations of the various network nodes and the optical gains of the various optical amplifiers to enable the optical network to carry the traffic in a manner that results in a higher throughput than that achievable with the use of conventional signal-routing and/or power-control methods.
    Type: Application
