Abstract
The present application relates to the technical field of vehicles. Provided are a communication method and apparatus based on a DDS, and a storage medium. The method comprises: a first DDS AIDE establishing a data transmission channel between a first DDS node and a second DDS node by means of a second DDS AIDE, wherein the first DDS node and the first DDS AIDE belong to a first component, the second DDS node and the second DDS AIDE belong to a second component, the first component, the second component, the first DDS AIDE and the second DDS AIDE support a DDS protocol, the first DDS AIDE corresponds to at least one DDS node comprising the first DDS node, and the second DDS AIDE corresponds to at least one DDS node comprising the second DDS node; and the first DDS AIDE assisting in data transmission between the first DDS node and the second DDS node on the basis of the data transmission channel. Thus, the data transmission performance can be improved.
