At present, the distance education system is usually be designed with a centralized server model, but our server's storage capacity is limited, therefore, server's storage capacity will be subsequently reduced until the last to fill up the server with the growing number of the files which from clients. So the center-Server will be easily become bottleneck of the system when we use a centralized server model to design the distance education system. In order to solve the problem above, the distance education system designed based on P2P technology will enable the most files be stored in the each client, the distance education system designed based on P2P can effectively improve the file storage capacity and network speed of the server. |
