1. A switch device for operating as an intermediate node in a Time Sensitive Network (TSN), the device comprising:
a storage unit storing a configuration, indicating for a flow, a timing in which a frame pertaining to the flow is to be output;
a processing circuitry configured to:
receive a frame pertaining to the flow,
determine whether the frame is a correct frame to be transmitted at a current time, including:
determining whether the switch device is about to send a right frame according to a corresponding predefined or preconfigured schedule;
in response to a to-be-sent frame being inconsistent with a predefined or preconfigured schedule, setting the switch device in idle instead of sending out the to-be-sent frame which is a different frame than intended; and
transmit the frame at the current time, only in response to determining the frame being the correct frame to be transmitted at the current time according to the configuration.
