AI Technical Summary

Technical Problem

In intelligent vehicles, the DDS middleware of the control node faces bottlenecks in bandwidth, computing, and memory resources, especially the packet processing pressure during the service discovery phase, which leads to performance degradation.

Method used

Each control node elects a master application, which represents the control node in external communication. Other applications do not directly conduct external communication, reducing the number of service discovery messages and optimizing network load and CPU resource usage.

Benefits of technology

It effectively reduces the communication complexity and data volume of the control node, alleviates the message processing pressure, and improves the operating performance of the control node, making it particularly suitable for resource-constrained vehicle environments.

Abstract

This application discloses a communication method, apparatus, device, medium, and product. The communication method includes: determining a main application running within a first control node, wherein at least one application runs within the first control node, and each application is a participant in a data distribution service; and communicating with a second control node through the main application running within the first control node. This technical solution, by determining a main application for the control node and using this main application to communicate externally on behalf of the control node for service discovery, effectively reduces the complexity and data volume of communication, alleviates the message processing pressure on the control node, and improves the operating performance of the control node. Other slave applications do not need to communicate externally.
