Apparatuses and methods for routing packets between a time-sensitive networking (TSN) network and a non-TSN network by virtual local area network (VLAN) tag manipulation

An apparatus, comprising:

• a storage medium, configured to store a first mapping of one or more first stream Identifiers (IDs) to one or more first Virtual Local Area Network (VLAN) tags, and a second mapping of the one or more first stream IDs to one or more VLAN tag indications;
• and
• a controller, coupled to the storage medium, and configured to route at least one packet between a Time-Sensitive Networking (TSN) network and a non-TSN network according to the first mapping and the second mapping;
• wherein the routing of the packet comprises:
• identifying a second stream ID of the packet;
• determining whether the second stream ID matches one of the first stream IDs in the first mapping or in the second mapping;
• in response to the second stream ID matching one of the first stream IDs and the packet being routed from the non-TSN network to the TSN network, inserting a VLAN tag in the packet based on the first VLAN tag corresponding to the matched first stream ID in the first mapping;
• and
• in response to the second stream ID matching one of the first stream IDs and the packet being routed from the TSN network to the non-TSN network, removing a VLAN tag from the packet based on the VLAN tag indication corresponding to the matched first stream ID in the second mapping.
