    Abstract: Systems and methods for method for data transport using secure reconfigurable branching units, including receiving signals from a first trunk terminal and a second trunk terminal by branching units. Broadcasting is prevented for secure information delivery by dividing, within the branching units, the one or more signals from the first trunk terminal and the second trunk terminal into two or more sections, and sending the two or More sections to an optical coupler. Signals may be received from a branch terminal by one or more branching units using two fiber pairs, and the signals from the branch terminals may be divided into two or more groups of optical sections, wherein one of the sections includes dummy light. The divided, signals from the first trunk terminal, the second trunk terminal, and dummy light from the branch terminal may be merged, and the merged signal sent to the branch terminal.

    Abstract: A generic centralized, software-defined networking configuration for connecting network is defined as a generic multi-layer topology network entities interconnected either vertically or horizontally regardless of the employed network topology/graph). This centralized configuration enables establishment of a connection between any two networking entities by 1) bypassing intermediate protocol layers and 2) eliminating any handshaking between peer elements of the same layer. The centralized software-defined controller notifies in parallel all involved network entities along a connection path to take all necessary actions (i.e. reconfiguration) to establish the new connection. The centralized controller has authority to control only entities that are software-defined SD.

    Abstract: Systems and methods are provided for network communication using wireless base stations and an optical orthogonal frequency division multiple access (OFDMA) signal generated on an optical wavelength, with the optical OFDMA signal being composed of a plurality of OFDMA subcarriers. A multi-level modulator modulates each of the plurality of OFDMA subcarriers. A single optical wavelength propagates each of the plurality of OFDMA subcarriers to different base stations; a passive optical splitter delivers the optical OFDMA signal to different base stations; and an OFDMA subcarrier de-multiplexer delivers and extracts traffic for each of the base stations in an electronic-domain, wherein the extracted traffic is remodulated in a wireless signal format. Antennas at each of the base stations transmit wireless signals, and the wireless signals are recovered and processed from the base stations.
