Claim 25:
26. A network configured for Time-Sensitive Networking (TSN), comprising:
an end station operable to transmit and receive TSN messages on the network, each TSN message having a frame therein;
a network infrastructure device connected to the end station and operable to send and receive TSN messages to and from the end station, respectively;
a network test access point (TAP) device connected to, and operable to copy TSN messages from, the end station and/or the network infrastructure device; and
a network controller connected to the end station, the network infrastructure, and the TAP device, the network controller operable to instruct the TAP device to initiate time data capture;
wherein the TAP device is further operable to insert, in response to being instructed by the network controller to initiate time data capture, current network time data in a predetermined number of frames and transmit the frames to the network controller; and
wherein the network controller is further operable to determine how much transmission jitter and/or latency is present using the current network time data in the frames.
