9. How Content Connects Has Changed Before Peering Tier 1 $ $ $ $   Both content and Tier 2 networks pay transit to reach each other

10. Tier 1 $ $ $ $   Savings of between 40% - 70% of bandwidth costs   Significant increases in performance with no hop access to end users   Networks with eyeballs gain dominance over old carriers After Peering Public Peering On GigE Exchange How Content Connects Has Changed

11. GigE Exchange   312 ports have been allocated to roughly 140 of the over 825 Equinix customers.   Aggregate peak has exceeded 50gig, well over 100% growth in first half of 2004.

12. Change of Value, Change in Pricing  Current price of IP transit (connectivity) with 1 year commit at 10-100 megs: $5-15/M  Current price of IP transit with a 30 day commit at any megs: $25-30/M  Current price of TRANSPORT (private WAN): $10-15/M

13. Before The Shift  In 2001, most content and eyeball networks were 100% transit  A typical broadband network or content paid for every packet delivered  Demands on broadband were limited  Costs were rapidly accelerating  “We’re waiting for the killer app.”  “We’re waiting for proliferation of broadband.”

14. After The Shift  In 2004, major content is over 50% peered  In 2004, major broadband is over 70-80% peered  Since 2002, report from FCC (September, 2004) indicates the number of broadband users have tripled to 48 million subs  Networks without eyeballs or content have limited value  New applications driving massive change in Internet food chain

15. Case Study: Yahoo! and SBC  In 2000/2001, Yahoo! paid for every packet delivered (transit or CDN)  In 2004, to SBC alone, Yahoo! provisions over 25-30 gigabytes/sec, more than any other broadband network  In total, Yahoo! sends out about 40-50 gigs  SBC now handling more eyeballs and content than most other broadband networks  Next month, all of these figures will TRIPLE.  SBC buys the remainder from Sprint… ?  Comcast is waiting in the wings…

16. Case Study: Netflix  In 2004, Netflix announces they will be offering downloadable 4gig movies  In 2004, Netflix announces relationship with Tivo  In 2005, Netflix will offer these downloads to their over 2.5 MILLION users on broadband…  Not even technically possible without direct to eyeball network relationships!  Announcements from Amazon.com and Wal-Mart offering identical offerings

17. Case Study: Apple  Apple iTunes offers the legal digital distribution of large copyrighted content  In 2004, Apple uses a combination of transit, peering and CDN to accommodate demand  Audible.com, AudioFeast and others add other materials, such as books on tape  Volume of content forcing bypass of commodity networks

18. Case Study: VoIP  Expectation is that broadband is required for consumer VoIP  VoIP providers offering voicemail and other features stored centrally  Non-tech consumers, with adapters, expected to adopt seamlessly  Unknown volume impact, though broadband providers implementing QoS for inter-provider connections
