Abstract: Systems and methods for supporting multiple time synchronization protocols within an industrial device include obtaining a time reference from each industrial device within the first set of industrial devices and the second set of industrial devices. The time reference provides the basis for synchronization of the clock and other clocks of first set of industrial devices and the second set of industrial devices. A principal time reference is selected from among the time references. Once selected, the principal time reference is correlated with each of the time references obtained from the first set of industrial devices and the second set of industrial devices. With the principal time reference correlated, related communication with the second device may be controlled.

Abstract: A method for operating a time-sensitive network (TSN) includes splitting data stream on network elements into a “preempting” class and a “preemptable” class based on a mapping from priority labels; forwarding the data streams to respective next-hop network elements, wherein the forwarding of “preempting” data streams takes precedence over the forwarding of “preemptable” data streams; and forwarding the data streams received from both segments based on the priority labels and the classes of the data streams to at least one next-hop network element; wherein forwarding of “preempting” data streams takes precedence over forwarding of “preemptable” data streams; wherein the priority label attached to the data stream that has the highest priority is different from the priority label attached to the data stream that has the highest priority within the second segment.
