P2p networks

  1. 1. • P2P Stands for Peer to Peer • A network of personal computers, each of which acts as both client and sever, so that each can exchange files and email directly with every other computer on the network. • Each computer can access any of the others, although access can be restricted to those files that a computer's user chooses to make available. • P2P networking has generated tremendous interest worldwide among both Internet surfers and computer networking professionals. P2P software systems like Kazaa and Napster rank amongst the most popular software applications ever. Numerous businesses and Web sites have promoted "peer to peer" technology as the future of Internet networking.
  2. 2. • Computers in a peer to peer network are typically situated physically near to each other and run similar networking protocols and software. Before home networking became popular, only small businesses and schools built peer to peer networks.
  3. 3. • Most home computer networks today are peer to peer networks. Residential users configure their computers in peer workgroups to allow sharing of files, printers and other resources equally among all of the devices. • Both wired and wireless home networks qualify as peer to peer environments.
  4. 4. • When most people hear the term "P2P", they think not of traditional peer networks, but rather peer to peer file sharing over the Internet. P2P file sharing systems have become the single most popular class of Internet applications in this decade. • A P2P network implements search and data transfer protocols above the Internet Protocol (IP). To access a P2P network, users simply download and install a suitable P2P client application. • Numerous P2P networks and P2P software applications exist. Some P2P applications work only with one P2P network, while others operate crossnetwork. Likewise, some P2P networks support only one application, while others support multiple applications.
  5. 5. • You can configure computers in peer to peer workgroups to allow sharing of files, printers and other resources across all of the devices. Peer networks allow data to be shared easily in both directions, whether for downloads to your computer or uploads from your computer. • On the Internet, peer to peer networks handle a very high volume of file sharing traffic by distributing the load across many computers. • Essentially P2P Networks are a great way to connect and send resources to people in an easy way.
  6. 6. • Unfortunately sometimes these information-sharing systems have been used to engage in illegal activity. Some of the most common crimes associated with Peer-to-Peer networks are the following: • Copyright Infringement: It is a violation of federal law to distribute copyrighted music, movies, software, games, and other works without authorization. There are important national economic consequences associated with such theft. • Computer Hacking: Peer-to-Peer networks also have been abused by hackers. Because these systems potentially expose your computer and files to millions of other users on the network, they also expose your computer to viruses. Also, if Peer-to-Peer software is not properly configured, you may be unknowingly opening up the contents of your entire hard drive for others to see and download your private information.
  7. 7. • In the years ahead, expect the concept of P2P to continue evolving. The networking industry will introduce a wider range of peer to peer applications that should compete for attention with traditional desktop and client / server systems. P2P protocol standards will be adopted to a greater extent. Finally, the ramifications of free P2P application information sharing on copyright and intellectual property law will slowly be settled through the process of public debate.
