MultiClient MultiInstance Centralized File Server using TCP protocol in Java Sockets

Abstract

In today's scenario File Server using reliable connection oriented protocol like TCP are well active, but majorly they are task specific like for chat server, document file server, image server, audio file server or Video Server etc. If they all are present together the server might be using other file transfer protocol and application is not transparent. To promote easy and transparent file transfer across network using Java Sockets, we introduce a Java TCP Server. The Server is multiclient multithreaded multi format supported Java Application. The requesting client validates the user request at its end and improves server performance; on other hand Server provide data only to authenticated client and refuses connection to others. The server is profiled for number of clients for mixed type of Input files like text, doc, pdf, jpeg, mp3, flv and mp4. The client server design is well implemented on 2, 4, and 8 systems in our laboratory and tested for heap memory usage, server usage time and bandwidth utilization; results are well satisfied and become platform for this paper.
