Design and Realization of Rocket Battalion's Communication Network Simulation Based on UML

To resolve the army's problems in training and teaching about the new equipment, a scheme of communication network simulation system was introduced after making a study of the internal constitution and command flow of the rocket battalion's communication network. UML and Rational Rose were applied to make the requirement analysis and overall design .With the help of the static views and activity views, it gave a visual description of the functional requirements and function process, structure and connection between classes, and state transition between objects. In programming, the problems about organizing communication networks and deducing voice transmission delay were resolved by the aid of the IP multicast technology and both buffer's recording by turns. By long time's probation, the communication network simulation worked well and met the design requirements.
