With the fast growth in the number of users and the data over the networks, the need to develop a system arises, that can serve to consume and provide the service of the users reliably. The peers in this type of network depends upon each other in order to provide a dedicated and server less system, which are named peer-to-peer systems. These systems doesn¿t have separate servers and client, instead the peers serve as both server and client.in p2p systems, all the peers are equally responsible for services related to server as well as clients. According to the research and study on p2p networks, it is found that these systems are very much effective when large number of peers are connected together in the same p2p network. Along with this highly important feature, p2p services are amplified with its special properties of decentralization, its robustness, the performance and the security. Here in this book i have discussed an approach that can combine the e-mailing and messaging services of an web application.
