AI Technical Summary

Technical Problem

In distributed systems, especially in autonomous driving systems, existing data transmission schemes struggle to balance high reliability and real-time performance. In particular, when using unreliable transport protocols such as UDP, transmitting large amounts of data can easily lead to buffer overflows and packet loss, affecting the stability of the communication link.

Method used

By serializing data in segments and sending each segment immediately after serialization, and using the serialization interval as the sending interval, the data sending rhythm is dynamically adjusted to avoid instantaneous traffic surges. This can be combined with synchronous or asynchronous sending methods to adapt to different needs.

Benefits of technology

Without increasing the total serialization time, it significantly reduces the packet loss rate during transmission, improves the transmission success rate, meets the real-time requirements of synchronous transmission scenarios, and avoids buffer overflow and packet loss.

Abstract

The invention provides a data sending method and device, equipment, a storage medium and a program product. According to a preset segmentation serialization rule, segmentation serialization is carried out on to-be-transmitted data to obtain segmentation serialization data, and the segmentation serialization data is sent to a data receiving end; updating the to-be-transmitted data based on the segmented serialized data; under the condition that the to-be-transmitted data is not fully serialized, returning to execute the step started according to the preset segmentation serialization rule; and determining that the to-be-transmitted data is completely sent until the to-be-transmitted data is completely serialized. According to the invention, the data is sent in a segmented and serialized manner, and the serialization gap is used as the sending interval, so that the problem that the total end-to-end transmission delay is caused by sudden increase of instantaneous flow, packet loss of a transmission layer, retransmission repair of a protocol layer and the like due to too short sending interval is avoided; and compared with a mode of completely serializing the data and then transmitting the data, the packet loss rate in the transmission process can be reduced under the condition that the serialization and the total transmission time are not changed.
