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 includes one or more processors that determine a communication risk value for each path of multiple paths within a time-sensitive network. The multiple paths are defined by multiple nodes and links that communicatively connect the nodes. The processors establish a redundant path of the paths that bypasses a low reliability path of the paths. The redundant path includes at least one different link or node from the low reliability path. The processors control the time-sensitive network to communicate duplicate copies of a data frame in parallel along both the redundant path and the low reliability path to increase a likelihood that the data frame is received at a listening device from a publishing device within a designated time window according to a schedule of the time-sensitive network.

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: 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.
