The data interaction interface consists of three parts:
QualNet simulation engine data interface: This interface follows the specifications for the secondary development of external interfaces in QualNet. It listens to the requests and responses from external simulation control modules, and publishes the real-time simulation situation information.
External simulation control module data interface: This interface is called by external simulation control modules to issue simulation control instructions and listen for response information from the QualNet simulation engine.
DDS global data space: The publish-subscribe model establishes a virtual shared global data space for all distributed simulation modules. The Publisher of each module sends the data to the global data space, and the Subscriber obtains the corresponding data from the global data space according to their own needs.
