  • Publication number: 20210289514
    Abstract: A communication system includes multiple nodes of a time-sensitive network and a scheduler device. At least one of the nodes is configured to obtain a first signal that is represented in a frequency domain by multiple frequency components. The scheduler device generates a schedule for transmission of signals including the first signal within the time-sensitive network. The schedule defines multiple slots assigned to different discrete frequency sub-bands within a frequency band. The slots have designated transmission intervals. The nodes are configured to transmit the first signal through the time-sensitive network to a listening device such that the first signal is received at the listening device within a designated time window according to the schedule. At least some of the frequency components of the first signal are transmitted through the time-sensitive network within different slots of the schedule based on the frequency sub-bands assigned to the slots.

  • Publication number: 20210258095
    Abstract: A system and method determine a clock drift and a clock variance of each node in plural nodes of a time-sensitive Ethernet network. An accumulated clock offset along a time-sensitive network path in the time-sensitive network is determined based on the clock drifts and the clock variances. A guard band having a dynamic size is determined based on the accumulated clock offset. The times at which Ethernet frames are communicated through the nodes are restricted by communicating the guard band with the dynamic size to one or more of the nodes.

  • Publication number: 20210091935
    Abstract: A communication system includes a first quantum key distribution device and an intermediary device. The first quantum key distribution device is configured to be coupled to a second quantum key distribution device over a quantum channel and to generate a shared key with the second quantum key distribution device based on a quantum state transmitted along the quantum channel. The intermediary device is disposed along a communication pathway within a network between a sender device and a receiver device. The intermediary device is communicatively connected to the first quantum key distribution device and configured to utilize the shared key to authenticate one or more data packets communicated from the sender device along the communication pathway by examining the one or more data packets for a presence of an information pattern that is associated with the shared key.

  • Publication number: 20210029044
    Abstract: A method in a communication network includes determining a transmission schedule for a plurality of data sources. The transmission schedule is configured to meet communication requirements of both time-sensitive traffic and non-time-sensitive traffic of the plurality of data sources. The method may also include transmitting data according to the determined schedule by shaping the time-sensitive traffic and the non-time-sensitive traffic at the plurality of data sources according to the determined schedule and receiving a communication change command. The method may further include determining a new transmission schedule for the plurality of data sources, the new transmission schedule being configured to meet the communication requirements of both the time-sensitive traffic and the non-time-sensitive traffic in the changed communication network. The method may further include transmitting data according to the new transmission schedule.

The system also includes a traffic shaper of the TSN that receives a communication change from the control system at the TSN. The scheduling device changes one or more of the bandwidth for the communication of the time sensitive communications or the available bandwidth for the communication of the non-time sensitive communications in the TSN without restarting at least one network device of the TSN and while ensuring communications of both the time sensitive communications and the non-time sensitive communications.

  • Patent number: 10819462
    Abstract: Systems and methods described herein measure quantum bit error rates in links between switches in a time-sensitive network, identify an increase in the quantum bit error rate in a monitored link of the links between the switches, and modify a configuration of the time-sensitive network so that secret information is not exchanged over the monitored link associated with the increase in the quantum bit error rate. The systems and methods optionally can direct computing devices to change or update the quantum key at a rate that is no slower than a rate at which the messages or frames are communicated between the computing devices. For example, a new portion of secret information used for secure communications can be created for each message and/or each frame that is communicated.
