    Peer-to-Peer is a model of communication where every node in the network acts alike. It is as opposed to the Client-Server model, where one node provides services and other nodes use the services. Peer-to-peer computing takes advantage of existing desktop computing power and networking connectivity, allowing economical clients to leverage their collective power to benefit the entire enterprise.Peer-to-peer computing has been envisaged to solve computing scenarios which require spatial distribution of computation, spatial distribution of content, real-time collaboration, scalability or fault-tolerance at reduced costs. All these factors have influenced the emergence of stronger computing-capable peer-to-peer systems. Peer-to-peer (P2P) systems enable computers to share information and other resources with their networked peers in large-scale distributed computing environments. The resulting overlay networks are inherently decentralized, self-organizing, and self-coordinating. Well-designed P2P systems should be adaptive to peer arrivals and departures, resilient to failures, tolerant to network performance variations, and scalable to huge numbers of peers (tens of thousands to millions). As P2P research becomes more mature, new challenges emerge to support complex and heterogeneous decentralized environments for sharing and managing data, resources, and knowledge with highly dynamic and unpredictable usage patterns. Peer-to-peer computing has been successful in attracting more peers due to its rich contents, fast response time and trust worthy environment. The enormous applications available on the internet are further strengthened with the application of peer-to-peer computing. This paper intends to review the background, challenges and future of P2P Networking.

    Peer - To - Peer File Sharing: Offline Approach
    (2015-07) Rachana C R, Associate Professor & Head, DoS in Computer Science, PG Wing of SBRR Mahajana First Grade College (Autonomous) Pooja Bhagavat Memorial Mahajana Education Centre, K.R.S. Road, Metagalli, Mysuru-16.
    The traditional method of transferring data within the Internet has followed the client-server paradigm. That means there is a known content provider, the server, to which the clients connect in order to receive the required data directly from the server. Thus, one needs powerful servers, which lead to high costs, to handle all the incoming requests. With home computers getting faster and high-speed Internet connections getting more and more common, relocating the task of content delivery away from the server seemed to be the next logical step. With the P2P model, however, there is no central server. Every computer connected to the network can act as a server and a client – both sending and receiving data – and the applications running on each PC works to find the most efficient way to share between each other, spreading the load and increasing the strength of the whole network.This paper brings to light the trends and an offline approach to Peer to Peer file sharing on the internet.
