【The Future of P2P】 by Eric Armstrong, Pres., Kontiki Inc. †

The BIG Opportunity †

• An enormous Digital Video Marketplace is Inevitable
• We are passed the threshold where
  • Digital compression + DRM + ecommerce + last mile broadband penetration
  • ...enables mass adoption
• On-Demand access of all popular media will eventually surpass Broadcast viewing
• But, there are still big problems to solve...

Kontiki Inc. †

• Founded in 2000 (7+years of experience), Kontiki is on its 5th major software release, Supporting 6+ million downloads per month, and growing
• Widely known as the industry leader in both Enterprise and Consumer Media P2P
• Kontiki is not a file sharing technology
• Core business (Software technology, Not a content aggregator, Not a CDN)
• Customers: Enterprise(Coca-Cola, Ernst & Young, GM, Wells Fargo, Wachovia, Charles schwab, VF Corp. Textron) Consumer Media(BBC, Sky, Open Media Network, moviefone, Cinequest)

P2P Early Years †

• 1999:napster 2000: Kontiki, Gnutella, eDonkey2000 2001: BitＴorrent
• Most early file sharing companies solved the "access to content" problem
• No Network Management
• Centralized publishing and tracking were avoided
• Delivery performance was best efforts

The Enterprise Driven Path †

• Built to manage "data" across complex networks (Not built for mass content delivery)
• Good edge connectivity
• Under-provisioned WAN segments meant to carry RT business traffic

Enterprise P2P deployments were driven by these requirements: †

• Make efficient use of existing network and computing resources
• Self-scaling
• Track and report on all networks and content consumption activities
• Protect sensitive content
• Guarantee a high quality of service, but not at the expense of real-time traffic
• Integrate with existing enterprise information & directory services
• [This should look familiar to those of you in consumer media P2P]

The Fundamental Difference †

• Enterprise requirements vastly more sophisticated requirements than consumer P2P file sharing systems (Kontiki solved these)
• Another fundamental difference is that enterprise P2P systems have robust Delivery Management:
  • Centralized Configuration and Control (Network and location specific rules set by the central administrator to determine peer behavior)
  • Distributed Dynamic Adaptation (The peering network adapting to the changing conditions of the network in a predictable way)

Converging Requirements †

• Consumer media requirements have now morphed to look very similar to the needs of the enterprise
  • It is a WAN problem more than a LAN problem
  • Need to be able to manage traffic flow by locale, by ISP, by content type and even by customer type (configurable and Dynamic)
  • Manageability, Security, Reporting are critical

The Way Forward †

• The joint challenges of Content Owners, Network Owners and Consumers look familiar (Match those of Enterprise market, that we have uniquely solved)
• DCIA ' The P4P working group have the right priorities
• Good news for the future of the Market
• We know how these systems need to work (Kontiki has solved the hard problems., We are proven in the market., Consumer media landscape looks very familiar to us., Kontiki is playing a leading role in these initiatives)
