Digital Divide: North Vs. South East Vs. West
Work on the Digital Dividefrom Several Perspectives
Share Information: Monitoring, Tracking BW Progress; Dark Fiber Projects & Pricing Track Planning (focus on LHC) and Leading Edge Progress Model Cases: Poland, Slovakia, Czech Rep., Brazil, China … Encourage Access to Dark Fiber; Modern technology choices
Raise Awareness: Locally, Regionally & GloballyDigital Divide WorkshopsDiplomatic Events: WSIS, RSIS, Bilateral: US-South Asia, EU-Africa,…

2001
In 2001, only ~20% of the world had an Acceptable or
Better Packet Loss Rate [49% unmeasured].
By 2008 this had improved to ~90%.
What matters as much now is throughput.
SCIC Monitoring WG – Throughput improvements 1998-2010
Mar ‘92
Top 4: Europe, N. America, E, Asia & Australasia,Behind Europe:5yrs: Russia, L, America, Mid East.8yrs: SE Asia13yrs: S. Asia, C. Asia18yrs: Africa
In 10 years: Russia and L. America should catch up with top 4.Africa falling further behind, factor 60 behind E. Asia
Derived TCP Throughput =1460Bytes*8bits/Byte/(RTT * sqrt(loss))Mathis et. al.
We have extended the measurements to cover more developing countries and to increase the number of hosts monitored in each developing country.
We have carefully evaluated the routes and minimum ping RTTs to verify that hosts are where they are identified to be in our database. As a result we have worked with contacts in relevant countries and sites to find alternatives, and about 20-30 hosts have been replaced by more appropriate hosts.
Since December of 2006, we have added a net of over 230 new remote hosts, and added 51 countries (Africa: BF, CD, CV, CI, DJ, GA, GM, GH, GW, LR, LY, MU, NA, SC, SL, SZ, TG, ZM; Balkans/S.E. Europe: BA, LV, MD; Central Asia: TM, Europe: AD, AT, BE, BG, CZ, FO, GI, LI, LU, SM, SE; Latin America: AN, BS, CO, CU, DO, NI; Middle East: AE, BH, OM, QA, SA; South East Asia: KH, LA, PH, TH; South Asia: AF, BT, MV).
While ping blocking is still a big problem as many hosts
start blocking over time, no countries were lost this year.

Ambitious plans are once again underway to better-connect the African continent, both East & West
Potential increase in capacity compared to now is 1000X: to the multi-Terabit/s range.
Is there is a sustainable market ?Before the recession, outlook was
at least one of these would succeed this time

IEPM Measurements of Fiber Cuts in the Mediterranean
December 2008(Also January 2008)
From the ICFA SCIC 2009Monitoring Report
Three undersea cables cut: traffic greatly disturbed between Europe and Asia/Near
East zone France Telecom observed Dec. 19 that 3 major underwater cables were cut:
“Sea Me We 4” at 7:28am, “Sea Me We3” at 7:33am and FLAG at 8:06am. Causes of the cut, located in the Mediterranean between Sicily and Tunisia,
on sections linking Sicily to Egypt, remain unclear. Most traffic between Europe and Asia rerouted through the USA. Traffic from Europe to Near East & Asia interrupted to greater or lesser extent.First estimate of percentage of out-of-service capacity): Saudi Arabia: 55% out of service Djibouti: 71% out of service Egypt: 52% out of service UAE: 68% out of service India: 82% out of service Lebanon: 16% out of service Malaysia: 42% out of service Maldives: 100% out of service Pakistan: 51% out of service Qatar: 73% out of service Syria: 36% out of service Taiwan: 39% out of service Yemen: 38% out of service Zambia: 62% out of service
