Comparative Analysis of Peer to Peer Networks

Today over the Internet, communication and computing environments are considerably and significantly becoming more and more chaotic and complex than normal classical distributed systems that have some lacking of any hierarchical control and some centralized organization. There in the emerging of Peer-to-Peer (P2P) networks overlays has become of much interest because P2P networks provide a good quality substrate to create a largescale content distribution, data sharing, and multicast applications at the application-level. P2P networks are commonly used as “file-swapping” in any network to provide support in sharing of distributed contents. For data and file sharing, a number of P2P networks have been deployed and developed. Gnutella, Fast track and Napster are three popular and commonly used P2P networking systems. In this research a broad overview of P2P networks computing is presented. This research is focusing on content sharing technologies, networks and techniques. In this research, it is also tried to emphasize on the study and analysis of popular P2P network topologies used in networking systems. This research is also focuses, identifies and describes the most common architecture models of P2P networks and compares different properties, characteristics and features of four P2P systems—Fast track, Gnutella, Open FT and Napster. In P2P organization, every peer grosses mutually the parts of the server as well of the client. By way of a client, it can demand and copy its required record files from additional peers, and in place of a server, it can offer data files to additional peers. The survey basically analyzes and outlines the basic structuring of P2P networks together with their analysis, comparison, applications, advantages, and disadvantages. The survey presents numerous organized and unstructured P2P structures.
