E.g.:Human Development Index(HDI) A long and healthy life, as measured by life expectancy at birth Knowledge, as measured by the adult literacy rate (with two-thirds weight) and the combined primary, secondary and tertiary education gross enrollment ratio (with one-third weight) A decent standard of living, as measured by GDP per capita (or Purchasing Power Parity (PPP) in US$). 6 1980 19902007 2000 Argentina gets worse in 90’s, S. America improves in 00’s, Africa improving long way behind

9 Some Other World Views Voice & video (de-jitter) Network & Host Fragility Data Transfer Capacity
10
10 World Measurements: Min RTT from US Maps show increased coverage Min RTT indicates best possible, i.e. no queuing >400ms probably geo-stationary satellite Between developed regions min-RTT dominated by distance - Little improvement possible Only a few places still using satellite for international access, mainly Africa & Central Asia 2000 2008
11
Loss 11 With TCP (>80% Internet traffic) recovery from loss can take several seconds, such delays make interactive use annoying to impossible. For non TCP multi-media traffic loss causes poor voice/video (VoIP/H323) above 1.5%,loss > 0.5% unacceptable for IPTV http://www.slac.stanford.edu/comp/net/wan-mon/tutorial.html#loss Africa by far worst region, 10-20 times worse than developed regions

16 African Situation Access to the internet is so desirable to students in Africa that they spend considerable time and money to get it. Many students surveyed, with no internet connection at their universities, resorted to private, fee-charging internet cafes to study and learn. www.arp.harvard.edu/AfricaHigherEducation/Online.html www.arp.harvard.edu/AfricaHigherEducation/Online.html Internet Café in Ghana School in a secondary town in an East Coast country with networked computer lab spends 2/3rds of its annual budget to pay for the dial-up connection. –Disconnects Heloise Emdon, Acacia Southern Africa 1 yr of Internet access > average annual income of most Africans, Survey by Paul Budde Communications Survey (IHY meeting Ethiopia in November ’07) of leading Universities in 17 countries (will repeat with more clarity): –Each had tens of 1000’s of students, 1000 or so staff –Best had 2 Mbits, worst dial up 56kbps –Often access restricted to faculty

21 What is happening: Fibre GEO-Stationary satellite $/Mbps 300 -1000 x Fibre, severely bandwidth-constrained,high latency Up until July 2009 only one submarine Fibre Optic cable to Sub-Saharan Africa, no competition, costly & only W. Coast 2010 Football World Cup => scramble to provide fibre optic connections to S. Africa, both E & W Coast Multiple providers = competition E. Coast: Seacom & TEAMs landed Jul 2009, Seacom working

They can get that much for the same sort of cash they’re already spending” Herlighy, Seacom CEO http://manypossibilities.net/african-undersea-cables SAT3
23
23 Impact: RTT etc. As sites move their routing from GEOS to terrestrial connections, we can expect: –Dramatically reduced Round Trip Time (RTT), e.g. from 700ms to 350ms – seen immediately –Reduced losses and jitter due to higher bandwidth capacity and reduced contention – when routes etc. stabilized Seacom live Thu Jul 23, ‘09 - reported by BBC & CNNBBCCNN 325ms Big jump Aug 1 ’09 23:00hr Median RTT SLAC to Kenya Bkg color=loss Smoke=jitter RTT improves by factor 2.2 Losses reduced Thruput ~1/(RTT*sqrt(loss)) up factor 3 720ms
24
24 From ICTP, Trieste, Italy Even Bigger effect since closer than SLAC –Median RTT drops 780ms to 225ms, i.e. cut by 2/3rds (3.5 times improvement) Aug 2nd Seems to be stabilizing Still big diurnal changes
25
25 Next Steps: Going inland Extend coverage from landing points to capitals and major cites Need fibre connections inland Central Northern Southern Connect up the rest of the sites & countries (UG, RW, ML..)
26
Other countries on Seacom Tanzania, also dramatic reduction in losses Uganda inland via Kenya, 2 step process Rwanda inland via UG & KE 3 steps Many sites still to connect SLAC to Uganda 1 direction, Aug 3 Both directions, Aug 15 Sep 27 SLAC to Tanzania SLAC to Kigali Inst of Education, Rwanda 720ms 320ms 22-25 Sep ‘09
27
Other Countries 27 750ms450ms SLAC to Angola Angola step mid-May, more stable Ethiopia Mar ’09, most measured hosts on GEOS Zambia half step Aug 20, 09 still trying on 2 nd step. Via Namibia & ZA Aug 20 SLAC to Zambia 1 direction Both directions? Mozambique May 2007 (via ZA) Malawi future probably via Mozambique South Africa since started measurements to it in Feb’05 Why does Haramaya in Dire Dawa have fibre connection before Addis Ababa the capital?
28
And… September 6 ’09 Glo-1 ubmarine cable landed in Lagos, Nigeria. This brings competition to the SAT3/WASC/ cable consortium.’Glo-1 ubmarine cable landed in Lagos, Nigeria In May 2010 the Main One cable will be landing on the West Coast of Africa, more competition.Main One cable All this adds up to factors of 2 or more times improvement in 1-2 years for many hosts in many African countries. Hopefully this will dramatically help the rate of catch up. 28

Beyond fibres reach ABUJA Africa's first communications satellite suffered an energy failure just 18 months after its launch - Nov. 2008ABUJA In areas where fibre connections are not available (e.g. rural areas), the main contenders appear to be: –wireless, e.g. microwave, cellphone towers, WiMax etc., –Low Earth Orbiting Satellites (LEOS) for example Google signed up with Liberty Global and HSBC in a bid to launch 16 LEOS satellites, to bring high-speed internet access to Africa by end 2010,Google signed up with Liberty Global and HSBC in a bid to launch 16 LEOS gigaom.com/2008/09/09/google-invests-in-satellite-based-internet-startup/ –and weather balloonsweather balloons www.internetevolution.com/author.asp?section_id=694&doc_id=178131& http://crossedcrocodiles.wordpress.com/2009/06/26/undersea-broadband- fiber-optic-cables-to-africa/http://crossedcrocodiles.wordpress.com/2009/06/26/undersea-broadband- fiber-optic-cables-to-africa/ Wireless mobility –then wireless (cell phone, wimax, LEOS…) –cell phone growth leads Internet growth by 4.5 years –failure just 18 months after its launch - Nov. 2008 29

Need for NRENs & IXPs 31
32
32 IXPs a Major Issue for African Internet International bandwidth prices are biggest contributor to high costs African users effectively subsidise international transit providers! Fibre optic links are few and expensive reliance on satellite connectivity High satellite latency slow speed, high prices Growth of Internet businesses is inhibited In 2003 10 out of 53 countries had IXPs More IXPs lower latency, lower costs, more usage Both national and regional IXPs needed Also needed: regional carriers, more fibre optic infrastructure investment Need NRENs country ->region –Then international IXPs Internet A B IXP Américo Muchanga americo@uem.mz, americo@uem.mz 25 September 2005
33
33 Routing Used to typically go through a satellite provider such as Newskies Now TZ, UG & KE go via London and Teleglobe & terrestrial fibre IXPs starting up, e.g. S. Africa direct to Namibia, Botswana, Mozambique Burkina Faso direct to Mali, Senegal, Benin Ubuntunet Alliance > GEANT Founders: Kenya, Malawi, Mozambique, Rwanda South Africa Joined by DRC, SD, TZ, UG S. Africa Burkina Faso
34
34 Next Steps: Let’s get together Get leaders such as universities, academic establishments (teach the teachers) to get togeher to form NRENs for country Bargain for cheaper rates BW most expensive worldwide ($4K/Mbps) Then NRENS get together to create International eXchange Points (IXPs) –Avoid intercountry links using expensive intercontinental links via Europe and the US.

37
37 Conclusions: The bad Poor performance affects data transfer, multi-media, VoIP, IT development & country performance / development DD exists between regions & countries, rural vs cities, poor vs rich, old vs young… Decreasing use of satellites, expensive, but still needed for many remote countries in Africa and C. Asia Last mile problems, and network fragility Current providers (cable and satellite) have a lot to loose –Many of these have close links to regulators and governments (e.g. over 50% of ISPs in Africa are government controlled) Africa worst by all measures (throughput, loss, jitter, DOI, international bandwidth, users, costs …) and falling further behind.
38
Conclusions: There is Hope World cup: international fibre access + competition LEOS Leapfrog last mile fixed wire with wireless Cheaper end points: OLTP, net computer, smart-phones Banding together of universities => leverage influence & get deals => NRENs => IXPs Users –E.g. Ubuntunet, Bandwidth Initiative Standards: –Harmonization of regulations country to country –Cheaper cell phone, can’t afford multiple technologies & frequencies Regulatory regimes becoming: – more open/transparent, less resistant to change 38 “The way we develop here in Africa will be different from the way the big nations developed. They grew up with computers. We are growing up with mobile phones. - Fritz Ekwoge”

HDI, DOI, DAI, NRI, TAI, OI.. In general agree with one another (R 2 ~0.8) Given importance of Internet in enabling development in the Information age some metrics we can measure: –International bandwidth –Number of hosts, ASNs –PingER Internet performance See if agree with development indices. –If not may point to bad PingER data or illuminate reasons for differences –If agree quicker, cheaper to get, continuous, not as subjective –Working to extend PingER coverage (120=>156 countries, 45 in Africa)

71 Fibre Links Future –SAT-3 shareholders such as Telecom Namibia, which has no landing point of its own find it cheaper to use satellite Will EASSy follow suit? Another option to EASSy: since Sudan and Egypt are now connected via fibre, and the link will shortly extend to Ethiopia, there are good options for both Kenya and Uganda/Rwanda and Tanzania to quickly link to the backbones via this route SAT3 connects eight countries on the W coast of the continent to Europe and the Far East.
