MultiClient MultiInstance Secured Distributed File Server

This paper describes a Distributed File Server, implemented in Java Sockets, based on TCP protocol.The server responds file request of multiple formats like txt, doc, pdf, jpeg, mp3, mp4, flv etc to multiple clients at a time.The requested server first checks the requested file, with it.If file search is not successful then it turns toward other servers connected to it.The Dedicated Server performs client authentication based on Ipaddress of connecting client and maintains list of files present with other servers connected with it.The clients at it end perform check on user requests, for better server performance.The system proposed is well tested in our laboratory with 0, 2, 4, and 8 clients connecting in distributed environment.Results of heap memory utilization and relative server utilization time in serving varying number of clients is drawn and analyzed.
