A file service mechanism for distributed systems

Experimental file service mechanisms are introduced for distributed systems. The implementation as a prototype in a computer network is presented. In this prototype there exist multiple server processes, client processes, and one server manager process. According to the user request, a file server process is assigned to a client process and activated by the server manager process. A file server has various operational modes. The mode is determined by the server manager to meet various application requirements. This process can also perform some functions for security enhancement. The file service mechanism helps network users to select any file server with its most efficient mode and ensures data integrity and security. This mechanism is combined with a high-level programming language provided by a client process and therefore offers high seviceability
