Design And Simulation Of Academic Peer To Peer Network

File sharing is the practice of distributing or providing access to digitally stored information, such as computer programs, multi-media (audio, video), documents, or electronic books. It may be implemented through a variety of storage, transmission, and distribution models and common methods of file sharing incorporate manual sharing using removable media, centralized computer file server installations on computer networks, World Wide Web-based hyperlinked documents, and the use of distributed peer-to-peer networking. In peer-to-peer networks, clients provide resources, which may include bandwidth, storage space, and computing power. As nodes arrive and demand on the system increases, the total capacity of the system also increases. In contrast, in a typical client–server architecture, clients share only their demands with the system, but not their resources. In this case, as more clients join the system, less resources are available to serve each client. As with most network systems, unsecured and unsigned codes may allow remote access to files on a victim's computer or even compromise the entire network. The distributed nature of peer-to-peer networks also increases robustness, and—in pure peer-to-peer systems—by enabling peers to find the data without relying on a centralized index server
