Switch for Scheduled Time-Sensitive Data Egress

摘要

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.

1. A method for scheduled data egress, comprising:
configuring a time-sensitive (TS) network switch to implement:
receiving one or more TS packets asynchronously from a network node via a first port, wherein each TS packet has a destination address and a type that specifies a respective egress period, wherein each egress period specifies a respective time window for egressing TS packets to network nodes based on the type of the TS packets;determining a second port for egressing at least one of the one or more TS packets based on the destination address of the at least one TS packet;determining an egress period for egressing the at least one TS packet based on the type of the at least one TS packet;determining that the at least one TS packet cannot currently be egressed from the second port;queuing the at least one TS packet in a first queue based on the respective TS packet type and destination address in response to determining that the at least one TS packet cannot currently be egressed, wherein the first queue is associated with the second port; andegressing the at least one TS packet in the respective time window from the second port.
