The Synchronization and Sharing Mechanisms for a Three-tier Server System Architecture in an E-Learning Platform

Abstract

A new mode of learning that has got popular with the use of internet enables the learners to share multimedia courseware instantly and to exchange opinions interactively. The process of information sharing is not working automatically. Situations like unsatisfied transmitting speed and even disconnections often occur when the servers are linked with ADSL. This research responds to the call of teachers and the network maintainers in the government and schools for a better platform structure ( three-tier Server System Architecture ), in which the three servers set up in government network center, schools and teachers’ laptops share and exchange resources automatically and immediately. This reinvented system is under the examination of the platforms served for Taipei Education Network Center, four elementary schools in Taipei, and the teachers’ laptops. The examination result shows this architecture is available, and can automatically exchanging and backuping the courseware to the network center. Meanwhile, synchronizing courseware to the schools far away from the cities is also workable.
