Research And Implementation Of Teaching-oriented Real-time Collaboration And Remote Multi-user Interaction Mechanism

With the rapid development of the Internet, the online teaching is becoming a newhot spot. The online teaching system supplies a teaching platform for teacher and studentswho are far away from each other. It starts online courses with teaching resourceseverywhere effectively.Traditional on-line teaching systems often make many videos which record someteaching courses in a classroom or PPT teaching progress, then put these resources on theInternet. Students log in and learn new knowledge by watching these videos. This is oneway of instilling teaching methods, and not be good for interaction between teachers andstudents. This kind of on-line teaching method is boring and can’t catch the eye ofstudents.This paper designs a teaching system which is based on a multi-user, real-time,collaborative and interactive method. It studies the CSCW technology and real-timeprocessing of multiple remote data. This system uses the C/S architecture and includesmulti-user, real-time and interactive tool, the design of synchronous controlling strategyand optimization of synchronous control. With the function libraries supplied by.NetFramework and form programming, the system is accomplished. The synchronouscontrolling strategy uses centralized authentication method to manage the synchronoustransmission. The synchronous control optimization enhances the system performance byoptimizing algorithm.This paper studies the related technology of computer supported cooperative work,describes the real-time processing multiple remote data transmission, and TCP packets"sticking" problem is also studied. This paper resolves several key issues: the one-way andtwo-way synchronization user operation; synchronous operation and local operationsrespond at the same time; synchronous control centralized authentication management;real-time transmission and processing of data. Finally, the system achieves the basicfunctions by testing.
