Presentation to France Telecom Ashwin Navin Co-Founder, Chief Operating Officer ashwin@bittorrent.com
The BitTorrent Mission • Make the Web effective for digital distribution improve serving / downloading large files help users discover / publishers be discovered
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: • User experience suffers due to server strain • 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
The Solution: Cooperative Distribution HTTP:// BitTorrent
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
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
Rapidly growing user base • BitTorrent mainline users now exceed 45 million through organic demand, word-of-mouth publicity
BitTorrent usage on tier-1 ISP BitTorrent traffic All non-P2P traffic
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
The BitTorrent (Cachelogic) solution • Manage Impact • Last mile congestion • Technical and support infrastructure • QoS improvements • Mitigate Costs • Reduce opex for network access/transit • Reduce capex • Maintain User Experience • Boost customer satisfaction • Minimize subscriber churn
