摘要： 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.

摘要： 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.

摘要： A system and method for remote object sensing which features a spatially polarization-inhomogeneous light beam that is directed on the remote object. A polarimetry receiver receives the light beam after it contacts the remote object. The changes in the spatially polarization-inhomogeneous light beam from contacting the remote object are a result of spatial features of the remote object. The polarimetry receiver is configured to measure the spatially inhomogeneous electric field of the light beam after it contacts the remote object and compute the changes in the spatially polarization-inhomogeneous light beam in order to detect spatial features of the remote object. The system obtains high-resolution, real-time information concerning important spatial features of the remote object.
