A real-time message pushing system, including teacher side and student side, is designed and implemented based on the WebSocket protocol aimed to improve the low efficiency in information exchange between teachers and students and to overcome the difficulty in getting the statistical feedback. At the same time, the key models and major technology are thoroughly investigated and analyzed. The results of the test indicate that the proposed system is stable and robust, and it meets the needs of message pushing software in terms of high efficiency and property in real-time.
