Fair and efficient bandwidth allocation for peer-to-peer networking

Summary: Jason Nieh, Ph.D.

Technology Benefits: Enforces fair bandwidth allocation by P2P clientsDiscourages freeloading users Rewards users who provide large amounts of upload bandwidth, incentivizing others to do soDoes not unfairly penalize users with low activity/bandwidth capabilityPromotes an increase in total bandwidth for P2P networkCan be implemented inside BitTorrent client without modification of the standard BitTorrent protocolPatent information:Patent Pending (US 20110131278)Tech Ventures Reference: IR M08-093

Technology Application: Decision-making software for P2P clients (bandwidth allocation for normal use, emergency/high volume scenarios, premium users)Data mining of upload/download trendsIdentification of good P2P users for promotional offeringsIdentification of malicious/freeloading P2P users (high download, low upload) and popular P2P sources of copyrighted material (low download, high upload)Digital distribution software using P2P
