2. 2 The BitTorrent Mission  Make the Web effective for digital distribution  improve serving / downloading large files  help users discover / publishers be discovered

3. 3 The Problem: http://  The Web does not enjoy broadcast economics  As a piece of content becomes more popular, digital distribution presents 2 problems to publishers: 1.User experience suffers due to server strain 2.Bandwidth costs become prohibitively expensive  Good content dies due to its own success  “Freedom of the press is limited to those who own one” - A.J. Liebling

4. 4 The Solution: Cooperative Distribution HTTP://BitTorrent

5. 5 The Solution: http:// BitTorrent  When BitTorrent is employed  Download performance improves as popularity increases  Bandwidth costs fall for the publisher  BitTorrent harnesses abundant, unused (P2P) resources  Torrents live on the web  No central or proprietary network  Torrents are files hosted, pointing users to the tracker which creates an ad hoc network around each publication = “swarm”  Easy to monitor and manage  Tracker servers maintain file integrity, provide usage data, offer some security

6. 6 Evidence of success  Protocol accounts for 40%+ of all IP traffic  Mainline client software used by 45+ million users (other distributions push the total over 100 million)  BitTorrent enjoys fierce loyalty of coders, hackers, independent publishers, open-source community  Good content sees the light of day: open source software, independent video/audio, public projects

7. 7 Rapidly growing user base  BitTorrent mainline users now exceed 45 million through organic demand, word-of-mouth publicity

8. 8 BitTorrent usage on tier-1 ISP BitTorrent traffic All non-P2P traffic

9. 9 The BitTorrent effect  Traditional Internet Traffic  Content on well-connected servers  Traffic asymmetrical  download:upload ratio 10:1  BitTorrent Traffic  Every user bears the burden of serving  Traffic symmetrical  download:upload ratio 1:1
