Cisco Visual Networking Index - Forecast and Methodology, 2007–2012P2P as a percentage of consumer Internet traffic dropped…the decline in traffic-share is due primarily to the increasing share of video traffic…Internet video will account for 50 percent of all consumer Internet traffic in 2012

DOCSIS 3.0 arrives ... download speeds up to 100 Mbps over the next two years and even reach speeds of up 160 Mbps farther down the road. Comcast has targeted the middle of 2010 for full

Latency insensitive content◦ Will existing infrastructure (caches/CDNs) scale or is

P2P really needed?

Move data closer to “customer locations”◦ Via CDNs◦ Via situating the data in “Internet Exchanges”◦ Via P2P

Latency sensitive content◦ IPTV/VoD with HD content well optimized by P2P

Hybrid schemes are likely – a P2P scheme used in tandem with CDNs/caches

Connectivity◦ Windows Vista offers ubiquitous connectivity

across NATs via IPv6 and various transitional technologies

Manageability Incentives Respecting copyright ISP impact and locality

End users P2P companies ISPs Advertisers Content providers Home router vendors Firewall vendors

This is just the tip of the iceberg We impact people’s lives in fundamental ways,

like few other technologies do We will know we are successful when normal

people are using p2p technologies everywhere, without even knowing they are

If TCP/IP was the fabric for the Internet of yesterday, P2P technologies are the fabric for the network of tomorrow

It is an honor to work with all of you to make this real
