Most popular in Computer Networks. Thus, the individual group leaders along with their child peers form a Napster-like structure. These group leaders then interconnect among themselves to resemble a Gnutella-like structure.

Centralized Directory It is somewhat similar to client server architecture in the sense that it maintains a huge central server to provide directory service. All the peers inform this central server of their IP address and the files they are making available for sharing.
The server queries the peers at regular intervals to make sure if the peers are still connected or not. So basically this server maintains a huge database regarding which file is present at which IP addresses. Working Now whenever a requesting peer comes in, it sends its query to the server. Since the server has all the information of its peers, so it returns the IP addresses of all the peers having the requested file to the peer. Now the file transfer takes place between these two peers.
Query Flooding Unlike the centralized approach, this method makes use of distributed systems. In this, the peers are supposed to be connected into an overlay network. In this overlay network, peers are called as nodes and the connection between peers is called an edge between the nodes, thus resulting in a graph-like structure.
P2P architecture is mostly suitable for small region area like as house and small office region because in this network every computer plays the role as independent workstation and it can save all data in own hard disk. Peer to peer architecture is designed with using of single software program where every piece of program performs their all tasks as both client and server along with similar responsibilities and capabilities.
There are various areas where to use P2P network , such as —. In this section, we will discuss about different types of Peer to Peer P2P network , below explain each one:. In this network, all peers play the role equally because this P2P network does not contain any centralized dedicated server. In this network, to connect every devices of network with each other is easy task.
All devices have to make same contribution, but due to lack of structure, users can face some difficulties for searching rare content. Its churn rate has higher, churn rare means how many users are joining and releasing of the network. Structured peer to peer network is not easy to set up compare to unstructured network, but it allows users excellent access for finding the rare content over the network.
