Abstract: A method includes identifying power connections between plural components of a time sensitive network (TSN) that are interconnected via a predetermined connection plan. The method also includes determining a topology of the components of the TSN based on the power connections. Also, the method includes scheduling flows for the TSN based on the topology determined based on the power connections.

Abstract: A communication system is provided that includes a first quantum key distribution device configured to be coupled to a second quantum key distribution device over a quantum channel that communicates a quantum state via the quantum channel, a classical device coupled to the first quantum key distribution device with a connection cable to provide a communication path between the classical device and the first quantum key distribution device, and a quantum channel carrier engaging the connection cable. The quantum channel carrier is configured to, responsive to movement of the connection cable, disrupt a quantum state within the quantum channel.

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.

Abstract: A locomotive control system includes one or more processors configured to determine quality of service (QoS) parameters of locomotive devices communicating data with each other in an Ethernet network that is configured as a time sensitive network (TSN) and that is onboard a locomotive. The one or more processors also are configured to determine available communication pathways in the TSN through which the locomotive devices are able to communicate the data. The one or more processors also are configured to select one or more of the available communication pathways and to designate communication times at which the data is communicated between the locomotive devices to satisfy the QoS parameters of the locomotive devices.

Abstract: A system includes a scheduling device of a data distribution service (DDS) that determines bandwidth for communication of time sensitive communications between devices using the DDS in a time sensitive network (TSN). The scheduling device determines available bandwidth for communication of non-time sensitive communications of the control system using the DDS in the TSN, and controls communication of both the time sensitive and non-time sensitive communications in the TSN. 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.

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.

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.

Abstract: A communication system is provided that includes a first quantum key distribution device and a communication 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 quantum key based on a quantum state transmitted along the quantum channel. The communication device is communicatively connected to the first quantum key distribution device within a network. The communication device is configured to receive the quantum key from the first quantum key distribution device and transmit the quantum key to an end device in the network via a classical link to enable the end device to use the quantum key for encrypting and/or decrypting messages communicated through the network.
