Common P2P Applications

In this article we will discuss Common P2P Applications , will make brief discussion on Common P2P Applications , In last article we discuss about Peer-to-Peer Networks.

Gnutella allows P2P applications to search for shared resources on peers. With P2P applications, each computer in the network running the application can act as a client or a server for the other computers in the network running the application. Common P2P networks include:

  • eDonkey
  • G2
  • BitTorrent
  • Bitcoin

Some P2P applications are based on the Gnutella protocol, where each user shares whole files with other users. As shown in the figure, Gnutella-compatible client software allows users to connect to Gnutella services over the Internet and to locate and access resources shared by other Gnutella peers. Many Gnutella client applications are available, including gtk-gnutella, WireShare, Shareaza, and Bearshare.

Many P2P applications allow users to share pieces of many files with each other at the same time. Clients use a small file called a torrent file to locate other users who have pieces that they need so that they can connect directly to them. This file also contains information about tracker computers that keep track of which users have what files. Clients ask for pieces from multiple users at the same time, known as a swarm. This technology is called BitTorrent. There are many BitTorrent clients including BitTorrent, uTorrent, Frostwire, and qBittorrent.

Any type of file can be shared between users. Many of these files are copyrighted, meaning that only the creator has the right to use and distribute them. It is against the law to download or distribute copyrighted files without permission from the copyright holder. Copyright violation can result in criminal charges and civil lawsuits.
