Message Flow Diagram: Data Distribution and Control Services
This content provides detailed information on the message flow diagram modes including Bootstrap, Tasking Mode, and Heartbeat Mode for Data Distribution Services. The diagrams illustrate the process of association requests, grant of association, capability advertisement, scanning schedules, authorization requests, status responses, periodic data publishing, and various control service interactions. It covers essential steps such as requesting and granting authorization, modifying schedules, refreshing associations, and terminating scanning activities. The diagrams offer insights into the communication flow within a control service environment. Check out the detailed descriptions for a comprehensive understanding of the message flow sequences.
