Description:

Discover the true potential of peer-to-peer networks

Napster, Kazaa, ICQ–file- and music-sharing peer-to-peer (P2P) networks have revolutionized the use of the Internet, but have also brought bad press to peer-to-peer computer networking. Yet P2P offers a great many legitimate benefits. Just witness the recent discovery of the largest prime number, a poster child for distributed computing!

P2P is a class of applications that leverages previously unused Internet resources–storage, cycles, content, human presence. Instead of large, expensive servers and pricey storage networks, corporations and other organizations can share data and computing duties among their desktops through P2P.

Legitimate Applications of Peer-to-Peer Networks goes beyond file and music swapping to explore the true potential of P2P technology in business and other important applications, including:

  • File sharing
  • Data storage management
  • Instant messaging
  • IP telephony
  • Collaborative content hosting
  • Publish-subscribe systems

Considering the merits and disadvantages of both the P2P and traditional approaches from a business perspective, Legitimate Applications of Peer-to-Peer Networks will help technology and business professionals realize the genuine–and legitimate–potential of this misunderstood and often misused technology
