Abstract: A node for a quantum key distribution (QKD) network includes an optical input that receives an optical pulse from a hub of the QKD network and an optical splitter that splits the optical pulse into an optical timing pulse and a pre-qubit pulse. The node also includes a qubit encoder controllable to encode the pre-qubit pulse into a photonic qubit; a qubit trigger circuit that controls, based on the optical timing pulse, the qubit encoder while the pre-qubit pulse propagates through the qubit encoder; and an optical output that transmits the photonic qubit to the hub.

Abstract: Systems and methods of operation are disclosed for media delivery systems operable to deliver requested media content to a client device by accessing media resources and media processing elements available on a network to which the media delivery system and client devices are linked. The media delivery system is operable to use the media resources and media processing elements to provide the requested media content in a requested format. The media delivery system may implement network-based media processing, and may use Immersive Technologies Media Format. The media delivery system may implement, such as in, or between, the application layer and network layer according to the OSI model, two control planes: a media control plane and a network control plane, and a data plane: a media data plane.

Abstract: A trust store management system for a network communication ecosystem is provided. The system is programmed to a) receive a DNSSEC entry address of a DNSSEC entry stored at a DNSSEC server; b) transmit a request to a DNSSEC server to access information stored in the DNSSEC entry associated with the DNSSEC entry address; c) receive, from the DNSSEC server, the information stored in the DNSSEC entry; d) receive a trust store; and e) validate the trust store based on the information stored in the DNSSEC entry.

Abstract: A client-side electronic device includes a receiver, a processor, and a memory. The receiver communicates with a message server over a communication medium of a communication network. The memory stores computer-executable instructions, which, when executed by the processor, cause the device to receive, from the message server, a broadcast message, a timestamp associated with the broadcast message, and a first digital signature of the broadcast message and a second digital signature of the timestamp. The executed instruction further cause the device to verify an integrity of the broadcast message based the first or second digital signatures, determine a freshness of the broadcast message based on the received timestamp, calculate a trust state of the broadcast message based on the integrity verification and the freshness determination, and store the broadcast message in the memory along with the calculated trust state.

Abstract: A method for synchronizing a timing end application (TEA) in an edge communication network includes (a) receiving, at a first access device, a time stamp from a first TEA communicatively coupled to the first access device, (b) transmitting the time stamp from the first access device to a second access device via communication media of the edge communication network, (c) adjusting the time stamp to account for transit time of the time stamp from the first access device to the second access device, and (d) after adjusting the time stamp, transmitting the time stamp from the second access device to a second TEA communicatively coupled to the second access device.

Abstract: An ad-hoc wireless network is implemented by a plurality of wireless access points to detect and report failure of a concurrently implemented conventional network. The wireless access points collect and store network status information of the conventional network and send the network status information to a centralized emergency manager when failure of the conventional network is detected. The ad-hoc wireless network may also provide backhaul connectivity to a wireless access point of the failed conventional network for emergency communication.

Abstract: A method for allocating bandwidth to a first ONU, a second ONU, M1 ONUs, and M2 ONUs includes, during an allocation cycle, (i) granting a respective upstream time slot to, of a plurality of N ONUs, only each of the M1 ONUs, and (ii) granting a first upstream time slot to the first ONU. Each of the M1 ONUs and M2 ONUs is one of the plurality of N ONUs. The method also includes, during a subsequent cycle, (i) granting a respective upstream time slot to, of the plurality of N ONUs, only each of the M2 ONUs. The N ONUs includes a skipped-ONU that is one of either, and not both, the M1 ONUs and the M2 ONUs. The method includes, during the subsequent allocation cycle, granting a second upstream time slot to a second ONU, which is not one of the plurality of N ONUs.
