Embodiment approach
[0115] Another possible implementation mode, mode 2, the service data transmission device determines the first type of service data packet from the first service data packets of the at least two transmission queues according to the scheduling time, priority and data packet size of the at least two transmission queues. For the service data packet, the first service data packet is the one whose size meets the preset size condition among the first type of service data packets.
[0116] The preset size condition may be that the size of the data packet is the smallest, or the size of the data packet is smaller than a threshold, etc., which can be flexibly set according to requirements.
[0117] As an example, the first type of service data packets in the above method 2 may have the following properties: the scheduling time of any service data packets in the first type of service data packets is equal, and the scheduling time of any service data packets in the first type of service d...

The invention provides a service data transmission method and device. The service data transmission method comprises the steps that the scheduling time of a first service data packet in at least two transmission queues in N transmission queues is determined, and N is a positive integer larger than or equal to 2; acquiring priorities of the at least two transmission queues and data packet sizes offirst service data packets of the at least two transmission queues; determining a first service data packet of one transmission queue from the at least two transmission queues as a first service datapacket according to the scheduling time, the priority and the data packet size; and transmitting the first service data packet. According to the method and the device, the transmission sequence of theservice data packets can be optimized, so that the transmission waiting time delay of the service data packets is reduced, and the QoS requirements of services, such as forwarding time delay and jitter, are ensured. The method can be applied to vehicles, especially intelligent vehicles, and can also be applied to other similar communication fields or application scenes related to the non-Internetof Vehicles.
Description
technical field [0001] The present application relates to communication technologies, and in particular to a method and device for transmitting service data. Background technique [0002] In the automotive communication network, the switching equipment aggregates and forwards various business data (such as audio and video, radar, CAN / LIN, etc.) to the data storage center or computing center. Advanced driving assistance systems and fully autonomous vehicles are very sensitive to the transmission delay and jitter of control and synchronization messages in the network. For example, for a car traveling at 120km / h on the expressway, the emergency braking message delay increases by 1 second, and the braking distance of the car increases by 33.33m, which greatly threatens the personal safety of drivers and passengers. Therefore, in order to ensure the Quality of Service (QoS) of various business data, the switching device needs to perform traffic shaping on the input business data...
