Analyzing distributed file synchronization techniques for educational data

“Movement of Enhancing Opportunities and Improving Technology”, abbreviated as Fatih, is among the most important educational projects in Turkey, in which students and teachers can use their tablet PCs to obtain educational data (text, images, media, etc.) stored in cloud servers. However, the limited network bandwidth and increase in both the number of users and their educational data sizes degrade the system performance and even negatively affect the overall usability of the system. Proxy server is a solution approach to both decreasing network traffic and increasing the efficiency in data transfers between end users (tablets) and cloud servers. In case of using a proxy server, synchronization problems arise. In this paper, distributed file synchronization approaches such as SyncML, Rsync and CouchDB have been reviewed and compared for their feasibility of employing in this school level proxy server based distributed systems architecture.
