3 Trends Multiple PC households, increasing laptops Explosion of devices in homes Opportunities A peer to peer fabric in the home to share and synchronize content across all devices (Live mesh) Efficient content distribution (Windows Vista) Challenges Power management How to identify a home

4 Web / File Server Branch Office

5 Trends Increasingly globalized; lots of branch offices Opportunities Distributed web caching (Squirrel) Content distribution to branches (Kontiki) Collaborative applications (Groove) Challenges Interplay of P2P with existing infrastructure AAA (Authentication, Authorization, Accounting)

6

7 Trends Petabytes and exabytes of data Tens/hundreds of thousands of servers Opportunities Data synchronization across servers Distributed data lookup (Amazon Dynamo) Distributed load balancing Challenges High performance

8

9 Trends Disaster zones – Humanitarian relief efforts Coffee shops Opportunities P2P first responder (ST Electronics) Adhoc sharing (Zune, Windows Meeting Space) Challenges Setup

11 AT&T Backbone Sees 20% P2P Drop Backbone-Sees-20-P2P-Drop Hulu, YouTube and other alternative video 'taking over'http://www.dslreports.com/shownews/ATT- Backbone-Sees-20-P2P-Drop Cisco Visual Networking Index - Forecast and Methodology, 2007–2012 P2P 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 DOCSIS

12 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

13 Connectivity Windows Vista offers ubiquitous connectivity across NATs via IPv6 and various transitional technologies Manageability Incentives Respecting copyright ISP impact and locality

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

15 Wake up in the morning you see the pictures you took last night displayed on all panels in the house (picture frame, PC, TV) the computers are all updated to the latest anti-virus signatures you listen to the news streamed over IP TV

16 Wake up in the morning Take the company shuttle to work Meet a colleague on the bus Exchange a presentation that he needed without USB sticks!

17 Wake up in the morning Take the bus to work Work on your project Easily share files amongst each other; co-edit some documents and then upload to a document repository as needed

18 Wake up in the morning Take the bus to work Work Lunch Watch a funny video on youtube

19 Wake up in the morning Take the bus to work Work on your project Lunch A/V conference call with India Send the large training materials to the field office in India; everyone gets it fast

20 Wake up in the morning Take the bus to work Work on your project Lunch A/V conference call with India Ride back with your family Watch the episode of Lost that you missed the other day

23 Wake up in the morning Take the bus to work Work on your project Lunch A/V conference call with India Ride with a colleague back home Dinner Follow it up with a movie night with your son Sleep

24 This is just the tip of the iceberg We impact peoples 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

25 P2P Experiences IPv6 Teredo ISATAP 6to4 P2P Identities, Contacts PNRP People Near Me Serverless Presence and Publication Application Invitation Overlay Networks Message Multicast and Web Services Shared Database Replicated Files App and Desktop Sharing Addressing/ Connectivity Identity & Naming Discovery & Name Resolution Session Initiation Multiparty comm Application Services 25
