User Datagram Protocol Based Chat Application for Peer-Peer Connection

In this paper we proposed a system that a server can make the connections between clients and providing the port addresses to the clients to connect with each other. In this we have maintained security by giving port addresses so no other users can make access to the server. The UDP is a connectionless oriented transport layer protocol. Since the TCP does not provide the feature of Multicasting UDP is a widely used protocol that implement it. UDP's is stateless nature it is useful for servers that answer small queries for the large number of clients. In the this paper we propose a method to make a chat room using socket based on User Datagram Protocol (UDP) which will enables the feature of acknowledgments after every message sent[2]. It is equivalent to a dedicated chat server having a Server and n number of Clients. After the client and server set up is connect, then you can achieve many machines to communicate through peer to peer communication, multicasting. During communication taking place there is might be different system and network failures will occurring, which we have discussed and proposed a convenient solution for that. Socket programming helps to implement of bottom level of network communication, using Application Programming Interface (API). The network management model has been taken as basis for the development of the new MPLS-TP packet transport network technology.
