A module monitors an arrival time of a frame at a node that selectively transmits frames from different flows in different time windows. The module determines whether the arrival time is within a time window and generates a signal in response to the arrival time being outside of the time window. In some cases, the frame is received at an ingress port of the node and the arrival time of the frame is recorded in an event database in response to receiving the frame at the ingress port. The arrival time of the event is accessed from the event database and this information is used to determine whether the arrival time is within the time window. The time window can be modified in response to the arrival time being outside the time window.

Notification of timing mismatches for queues in time sensitive networking

A node is configured for deployment in an optical network. The node includes an analog switch for routing an optical packet between input ports and output ports. The node also includes digital processing circuitry configured to generate first configuration information based on the optical packet prior to providing the optical packet to the analog switch. The analog switch is configured to route the optical packet between the input ports and the output ports based on the first configuration information in response to the optical packet arriving at the node in a first time interval. The optical packet is not processed by the digital processing circuit or results of processing are not used to configure the analog switch during a second time interval. The analog switch routes the optical packet between the input and output ports based on second configuration information during the second time interval.
