Decentralised indexed based peer to peer chat system

The paper introduces a decentralized chat system (developed in J2SE - Java Server Edition) for both intranet and internet. It is a zero-configuration model allowing users to simply run the application to communicate. Core to the system is an index table which notifies each user about the presence of other peers using the application over the network. Features include: Simultaneous communication between `n´ numbers of peers, multi-user communication invitees, conference, and file transfer between two peers. The communication system is based on simple Socket programming with IP and Port Address being detected by the Index. The user interface is prepared using Swing and AWT functionality.
