Reducing Cross-ISP Traffic in P2P Systems Using Adaptive Search Radius

Peer to Peer communication has become very popular these days .This popularity and increase in P2P traffic has given birth to many internet traffic management problems for service providers. One of these problems is high download traffic of P2P file sharing application for long network distances ,as current applications do not pay attention to network topology while selecting peers for sharing data .To reduce this trans network traffic various solutions have been suggested but all of them lead to compromises for upload rate, or file availability ,or external infrastructure on the internet to support the solution. This papers suggest a modified version of Adaptive search radius algorithm for BitTorrent to solve the problem , at minimum compromise to efficiency of file sharing applications .This papers shows how BitTorrent protocol react to modified adaptive search radius , as it is the most favored application for peer to peer file sharing .
