Study on Embedded Real-time Network Communication Protocol Model

摘要

Concerning the existing problems of embedded system's connecting to Internet, a new model of embedded real-time network communication protocol was presented. The model has excellent compatibility and universality. Furthermore, protocol of hardware layer won't be modified. The design theory, the logical structure and the implementation of the model were illuminated in the paper. Finitude state machine of processing Web server and IP layer and program of implementing model were provided. Communication protocol model was testified by simulating exclusive network environment in the experiments. The conclusion: Even though the number of network node is larger, response time between servers and clients can be controlled within 22 milliseconds, which can meet demands of real-time application.
