Abstract:
The client/server model has long been recognized, and new techniques were heavily applied during the recent years. However, considerable amount of problems, such as files representation, security, interworking, and drives mapping, still exist. The Thesis consists of creating a DOS client/server model, which uses TCPIfP as a communication protocol. Such a model can be simply installed in a UNIX network without the needs for protocol converter, and DOS is no more isolated from UNIX network. In addition, it will add to the client local drives, the server drives, thus, increasing the client capacity of files storing. The analysis includes client structure, server structure, client/server protocol, and hardware limitations. A source code' is developed for both client and server to demonstrate the real work of this model. The experiment consists of loading the developed server program on a PC, and testing it in a UNIX LAN network, as well as, installing the developed client software, and establishing a simultaneous logging to both servers. As a result, the access to the server drives from several applications such as Microsoft Windows, MSD, and others was attained. The results of this study were successful proving general applicability on a wide range of hardware.
