A network device for industrial control includes at least one processor, configured to operate a first operating system (OS) to process data forwarding with TSN standards and operate a second operating system to operate with an industrial protocol to process industrial control; and a communication protocol processing module, coupled to the at least one processor, configured to process network traffic of the first operating system and the second operating system according to a synchronized time. The first operating system and the second operating system perform time synchronization through a time message to obtain the synchronized time.

Network device and time synchronization method thereof

A time synchronization method for a time synchronization device, wherein the device is connected to a plurality of time synchronization domains through a plurality of ports, and the plurality of time synchronization domains use a plurality of PTP profiles. The method comprises determining whether each of the plurality of ports is a time receiving port or a time transmitting port; obtaining information of a grandmaster clock of the plurality of time synchronization domains; performing information conversion on the information of the grandmaster clock according to a PTP profile corresponding to each time transmitting port of the plurality of ports in the plurality of PTP profiles, so as to generate a plurality of clock information corresponding to each time transmitting port; and transmitting a corresponding clock information of the plurality of clock information to a corresponding time synchronization domain from each time transmitting port, so as to perform time synchronization.

Method and device for time synchronization of time synchronization domains

An apparatus including a storage medium and a controller is provided. The storage medium stores a mapping of stream Identifiers (IDs) to Virtual Local Area Network (VLAN) tags. The controller is coupled to the storage medium and configured to route a packet for a Time-Sensitive Networking (TSN) network according to the mapping. The routing of the packet includes replacing a VLAN tag in the packet according to the stream ID of the packet and the mapping, so as to maintain the real-time deterministic behavior of delivering data streams in the TSN network.

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

An apparatus including a storage medium and a controller is provided. The storage medium stores a first mapping of stream Identifiers (IDs) to VLAN tags, and a second mapping of the stream IDs to VLAN tag indications. The controller is coupled to the storage medium and configured to route a packet between a Time-Sensitive Networking (TSN) network and a non-TSN network according to the first and second mappings. The routing of the packet includes inserting or removing a VLAN tag in or from the packet according to the stream ID of the packet and the first and second mappings, so as to enable interoperability between the TSN network and the non-TSN network.
