Description
Summary:Due to the large number of visitors, the teaching assistant system is required to have high operation efficiency. Based on this, a multimedia distance teaching assistant system based on MOOC platform is designed. The multithreaded TCP mode is used to improve the parallel transmission effect on the server side. The MOOC platform is used as the basis of system permission management. The design of the course module includes course creation and configuration, course notification, member management, job management, job scoring and resource management. The retrieval module is designed by calling Solr and adding an update mechanism, The communication module uses the MOOC platform to encapsulate the system socket, realizes the multi-threaded communication of the system with the support of authorized server and unauthorized server, and meets the effective operation under multiple requests. The test results show that under the condition of 60 parallel requests, the response time of the designed system is no more than 1s, the average number of requests that the system can process for retrieval per second is 54, the average response time is 1.852s, and the system can return results within 1s under the condition of 100 concurrent requests, which is better than the comparison system.
