  • NETWORK MANAGEMENT METHOD, NETWORK MANAGING DEVICE, AND RECORDING MEDIUM
    Publication number: 20170264388
    Abstract: A network management method executed by a processor included in a network managing device configured to manage a network in which a plurality of wavelength-multiplexed optical signals is transmitted, the method includes determining an active path and an auxiliary path for each of the plurality of optical signals; allocating, for each of links coupling adjacent nodes included in the network to each other, frequency bands to be used for the optical signals to the active paths for the optical signals so that frequency bands for the maximum rates of transmitting the optical signals do not overlap each other; and allocating, for each of the links, unallocated frequency bands within the frequency bands for the maximum transmission rates to the auxiliary paths for the optical signals.

  • Wireless network control system to perform on-off control for small cell
    Patent number: 9661569
    Abstract: A wireless network control system includes a macrocell base station configured to form a macrocell, at least one small cell base station configured to form a small cell disposed within the macrocell, and a control apparatus including a controller configured to execute a process of acquiring a first value indicating a traffic state of a wireless terminal using the macrocell and a second value indicating a traffic state of a wireless terminal using the small cell, and a process of setting OFF the small cell when an added value of the first value and the second value falls within a predetermined range related to the macrocell.
