A method for providing a deterministic behavior in a shared physical network is disclosed. The method may be performed in a device controlling a Virtual Local Area Network, VLAN, of the shared physical network. The method includes rate limiting amount of inbound traffic for each traffic flow in the VLAN and assigning a respective priority for each traffic flow in the VLAN.

The present disclosure relates to a transmission device, a reception device, and a communication system made compatible with more various uses and adaptable to a rule of packet modification prohibition on a transmission path.

The transmission device adds a packet header for extension different from a packet header for a physical layer to packet data obtained by packing data to be transmitted and generates an Application Specific payload limited as a protection range to be protected by prohibiting modification on a transmission path is generated, and adds at least a packet header for a predetermined physical layer to the Application Specific payload, to generate a packet for the physical layer. The reception device receives the transmitted packet for the physical layer and acquires the Application Specific payload from the packet. The present technology can be applied to, for example, a communication system used in connection with an inside of a mobile device or an in-vehicle camera.

The present application relates to the field of network communication technologies, and provides a packet processing method and device, an advertisement method and device, a bridge node, a source apparatus, a packet processing system, and a computer-readable storage medium. The packet processing method includes: receiving a time sensitive networking (TSN) service packet; querying, according to a packet header of the TSN service packet, a mapping table of service stream IDs and TSN-profiles, where the mapping table of service stream IDs and TSN-profiles is established according to advertisement information of a source apparatus; and processing the TSN service packet according to a result of the querying on the mapping table of service stream IDs and TSN-profiles.

This application discloses a network and a data transmission method and apparatus, and belongs to the field of communication technologies. The network includes a core device and an edge device. The edge device identifies a service type of a first service packet from the core device, and reports a service type identifier of the first packet to the core device. The core device determines a priority corresponding to the service type identifier based on a stored service priority correspondence, and forwards, based on the priority, a service packet belonging to a same service flow as the first service packet. A strong service identification capability of the edge device is used to precisely identify thousands of service types, and a strong entry storage capability of the core device is used to store a correspondence that records thousands of service types and priorities. This effectively avoids problems such as transmission congestion and a packet loss that are caused by an incapability of precisely identifying a service type and allocation of a same priority to service packets of different service types.

A VP includes a base vehicle and a VCIB. The VCIB includes a reception unit, an index value calculation unit, a transmission unit, and a transmission plan setting unit. The reception unit receives a control request for the base vehicle from an ADS. The index value calculation unit calculates an index value showing a degree of congestion of CAN communication. The transmission unit transmits a control instruction for the base vehicle generated based on the control request to the base vehicle. The transmission plan setting unit sets a transmission plan of the control instruction to the base vehicle. The transmission plan setting unit sets the transmission plan according to a degree of priority of the control instruction in CAN communication and the index value.
