Abstract:
Systems and methods for scheduling data egress using a time-sensitive (TS) network switch. The TS network switch may include a functional unit, a plurality of ports, and a plurality of queues. Each port may be associated with a set of network addresses for TS packets and may be configured with a set of egress periods. Each queue may be associated with a TS packet type and a port. The functional unit may be configured to receive TS packets asynchronously from a network node via a first port, determine a second port for egressing a TS packet, determine an egress period for egressing the TS packet, determine that the TS packet cannot currently be egressed from the second port, queue the TS packet in a first queue, where the first queue is associated with the second port, and egress the TS packet in the respective time window from the second port.
