Classification: CPC H | IPC H

Claim 7:
8. A method of operating a network configured for Time-Sensitive Networking (TSN), comprising:
generating, at a talker device, a frame with an initial timestamp at a preselected Open Systems Interconnection (OSI) layer, the initial timestamp reflecting then-current network time;
collecting additional timestamps as the frame traverses the OSI layers towards a network port of the talker device, each additional timestamp reflecting then-current network time;
transmitting the frame across the network via at least one infrastructure device, wherein at each preconfigured infrastructure device, the frame is timestamped at an ingress and an egress of the preconfigured infrastructure device;
receiving the frame at a listener device;
collecting the at least one additional timestamp as the frame traverses the OSI layers of the listener device, the at least one timestamp taken at a preselected OSI layer of the listener device; and
calculating, based on the collected timestamps, including the initial timestamp and the at least one timestamp, transmission jitter and/or latency in network traffic through the network.
