Design of data communication protocol in software test system

Simulation system is a real time system, in which data communication mechanism is the key point to assure the correctness of test data and real time data transferring. This paper will start from the architecture of simulation test system, and then build a data communication model according to data type and transferring requirements of the simulation test system. We present a test data communication mechanism based on data communication model. We elaborate the design of architecture of the communication mechanism and the design of software protocol.
