International Bandwidth Trends Internet2 – ITF Meeting April 24,2006

1. International Bandwidth TrendsInternet2 – ITF Meeting April 24,2006 Peter BarlettoSylvie LaPerrière

2. Toward optical cable build-out madness • The internet tsunami takes everybody by surprise. • The magic potion of DWDM : by the year 2000, cables of 1000 times the capacity of previous generation were being installed. • Deregulation, easy access to capital, advances in laser and fiber technology, early players gain high valuations and spectacular internet growth creates a new generation of global cable builders: Global Crossing, Level3, FLAG , 360networks, Tyco and results in a cornucopia of transmission capacity. • Internet folly: myth that traffic will double every 90 days forever. • Capacity prices plummet: Trepidation • Capacity providers go under

3. The big build out of the early 2000’s • Starting shot was given by Atlantic Crossing (AC1) which came on-line in May 1998 and TPC-5 on the Pacific side in December 98. • Level3, Global Crossing, FLAG, 360, TGN networks emerged as the major new generation cable builders. • The final achievements were the terabit level C&W TransAtlantic cable and the Tyco TransPacific cable; both came on line early 2003. • The Atlantic has 4 terabit level cables, the Pacific one • A trinity of East-Asia terabit level cables : EAC, C2C and APCN2 and a North Asia terabit loop: FNAL/RNAL

4. Could there be some oversupply? The gap between lit and design capacity Very few cable builds likely for the rest of the decade, less willingness to expand lit capacity before demand

5. Lit capacity versus demand • Cost to activate all major unlit capacity is high: • transatlantic capacity (9.6Tb) is estimated at $3.5 bilion and $3.9 billion transpacific (7.9Tb) and $12 billion intra Asia (15.6Tb). (source: Telegeography 2005) • Some additional lit capacity likely needed in 2006-2007 • Better equilibrium between supply and demand

6. Predictions and forecasts revisited • What will fill the capacity and how fast? • Current (2005) transatlantic: voice: 13.3Gb internet 773.2Gb; other (IPL etc): 62.5Gb • TeleGeography predicts for end 2007: a slow growth scenario of 1,570Gb a fast growth scenario of 1,955Gb • This still leaves ample capacity but who would dare this time around to predict it will take 17 years to fill the cable? • Internet represents approx 85% of all transoceanic capacity use and has seen renewed growth (32% in 2004, 52% estimate for 2005). • How fast will internet traffic soak-up excess? Any new international bandwidth hungry internet applications in sight? • Bandwidth prices still keep dropping but at a slower rate—is price stability coming?

7. Toward gigabit connectivity • First transatlantic gigabit level circuit : • 2001: 2.5 gig SURFnet to Chicago Starlight • First transpacific STM-4’s • 2001: two Transpac STM-4’s • 2002: first transatlantic 10gb • Surfnet leads again • The big R&E scare of 2002: • KPNQwest disappears, Teleglobe reorganizes • Global Crossing, L3 and Tyco become major lambda providers

8. Continued Technological and Deployment Progress • 40G technology coming (?), • Router Ports exist - $$ • Terrestrial DWDM available but - $$ • Subsea possible but final development, impact to ultimate capacity, and costs are issues . • More options on interfaces in undersea equipment (GigE, 10GigE) • Interest in filling in gaps in undersea footprint, prices still high in some parts of the world. • Suppliers becoming more customer and cost focused
