    Abstract: Systems and methods to authenticate a Non-Fifth Generation Capable (N5GC) device on a Residential Gateway (RG) include a wireline access network comprising the RG and a wireline-access gateway function (W-AGF). The RG connects to the W-AGF using a termination system (e.g., a Cable Modem Termination System (CMTS) and the like) to relay N5GC device messages received at the RG to the W-AGF and vice versa. During a registration/authentication procedure for the N5GC device, the W-AGF generates a Registration Request message on behalf of the N5GC device and sends the Registration Request message to an Access & Mobility Management Function (AMF) of a Fifth Generation (5G) core network. The Registration Request message includes an indication that the N5GC device lacks 5G capabilities (e.g., is N5GC). In response to the Registration Request message, the system causes the N5GC device to be authenticated at least partly in response to the Registration Request message.

    Abstract: A system for secure management of licensing and distributing virtual network functions (VNF) is provided. The system includes a VNF license manager, a VNF repository, and a VNF license database. The VNF license manager is in communication with the VNF repository and the VNF license database. The VNF license manager is programmed to receive a request for access to a first VNF from a virtual network. The virtual network is configured to execute the first VNF. The VNF license manager is also programmed to determine if the virtual network may access the first VNF based on one or more policies associated with the first VNF. If the virtual network may access the first VNF, the VNF license manager is programmed to retrieve the first VNF from the VNF repository and transmit the first VNF to the virtual network.

    Abstract: A digital receiver is configured to process a polarization multiplexed carrier from a communication network. The polarization multiplexed carrier includes a first polarization and a second polarization. The receiver includes a first lane for transporting a first input signal of the first polarization, a second lane for transporting a second input signal of the second polarization, a dynamic phase noise estimation unit disposed within the first lane and configured to determine a phase noise estimate of the first input signal, a first carrier phase recovery portion configured to remove carrier phase noise from the first polarization based on a combination of the first input signal and a function of the determined phase noise estimate, and a second carrier phase recovery portion configured to remove carrier phase noise from the second polarization based on a combination of the second input signal and the function of the determined phase noise estimate.

    Abstract: A beam steering subsystem is provided in an optical communication system. The beam steering subsystem is configured for steering a free-space optical (FSO) beam from a first transceiver to a second transceiver disposed remotely from the first receiver. The beam steering subsystem includes a beam steering device disposed between the first transceiver and the second transceiver, and an optical tracking unit in optical communication and electrical communication with the beam steering device. The wherein the beam steering device is further configured to (i) receive the FSO beam from the first transceiver, (ii) receive an optical tracking signal from the second transceiver, (iii) optically relay the received optical tracking signal to the optical tracking unit, and (iv) steer the FSO beam to the second transceiver based on an electrical feedback control signal from optical tracking unit.
