Quantifying the Digital Divide: A scientific overview of the connectivity of South Asian and African Countries:  Quantifying the Digital Divide: A scientific overview of the connectivity of South Asian and African Countries Les CottrellSLAC, Aziz RehmatullahNIIT, Jerrod WilliamsSLAC, Arshad AliNIIT Presented at the CHEP06 Meeting, Mumbai, India February 2006 www.slac.stanford.edu/grp/scs/net/talk05/icfa-chep06.ppt Introduction:  Introduction PingER project originally (1995) for measuring network performance for US, Europe and Japanese HEP community Extended this century to measure Digital Divide Last year added monitoring sites in S. Africa, Pakistan & India Will report on network performance to these regions from US and Europe – trends, comparisons Plus early results within and between these regions PingER coverage:  PingER coverage ~120 countries (99% world’s connected population), 35 monitor sites in 14 countries New monitoring sites in Cape Town, Rawalpindi, Bangalore Monitor 25 African countries, contain 83% African population Minimum RTT from US:  Minimum RTT from US Indicates best possible, i.e. no queuing >600ms probably geo-stationary satellite Only a few places still using satellite, mainly Africa Between developed regions min-RTT dominated by distance Little improvement possible Jan 2000 Dec 2003 World thruput seen from US:  World thruput seen from US Behind Europe 6 Yrs: Russia, Latin America 7 Yrs: Mid-East, SE Asia 10 Yrs: South Asia 11 Yrs: Cent. Asia 12 Yrs: Africa South Asia, Central Asia, and Africa are in Danger of Falling Even Farther Behind S. Asia & Africa from US:  S. Asia & Africa from US Data v. noisy but there are noticeable trends India may be holding its own Africa & Pakistan are falling behind Pakistan Compare to US residence:  Compare to US residence Sites in many countries have bandwidth< US residence India to India:  India to India Monitoring host in Bangalore from Oct ’05 Too early to tell much, also need more sites, have some good contacts 3 remote hosts (need to increase): R&E sites in Mumbai & Hyderabad Government site in AP Lot of difference between sites, Gov. site sees heavy congestion Pakistan to Pakistan:  Pakistan to Pakistan 3 monitoring sites in Islamabad/Rawalpindi NIIT via NTC, NIIT via Micronet, NTC (PERN supplier) All monitor 7 Universities in ISB, Lahore, KHI, Peshawar Careful: many University sites have proxies in US & Europe Minimum RTTs: best NTC 6ms, NIIT/NTC 10ms - extra 4ms for last mile, NIIT/Micronet 60ms – slower links different routes Queuing = Avg(RTT)-Min(RTT) NIIT/NTC heavily congested 200-400ms queuing Better when students holiday NIIT/Micronet & NTC OK Outages show fragility NIIT Holiday Pakistan Network Fragility:  Pakistan Network Fragility NIIT/Micronet NIIT/NTC NTC NIIT/NTC heavily congested Other sites OK NIIT outage Remote host outages Pakistan International fragility:  Pakistan International fragility Infrastructure appears fragile Losses to QEA & NIIT are 3-8% averaged over month RTT ms Loss % Feb05 Jul05 Fiber cut off Karachi causes 12 day outage Jun-Jul ’05, Huge losses of confidence and business Another fiber outage, this time of 3 hours! Power cable dug up by excavators of Karachi Water & Sewage Board Typically once a month losses go to 20% Routing in Africa:  Routing in Africa Seen from ZA Only Botswana & Zimbabwe are direct Most go via Europe or USA Wastes costly international bandwidth Between Regions:  Between Regions Red ellipses show within region Blue = min(RTT) Red = min-avg RTT India/Pak green ellipses ZA heavy congestion Botswana, Argentina, Madascar, Ghana, BF India better off than Pak Overall:  Overall Sorted by Median throughput Within region performance better (blue ellipses) Europe, N. America, E. Asia Russia generally good M. East, Oceania, S.E. Asia, L. America acceptable Africa, C. Asia, S. Asia poor Conclusions:  Conclusions S. Asia and Africa ~ 10 years behind and falling further behind creating a Digital Divide within a Digital Divide India appears better than Africa or Pakistan Last mile problems, and network fragility Decreasing use of satellites, still needed for many remote countries in Africa and C. Asia EASSy project will bring fibre to E. Africa Growth in # users 2000-2005 400% Africa, 4000% Pakistan networks not keeping up Need more sites in developing regions and longer time period of measurements More information:  More information Thanks to: Harvey Newman & ICFA for encouragement & support, Anil Srivastava (World Bank) & N.Subramanian (Bangalore) for India, NTC and PERN for Pakistan monitoring site, FNAL for PingER management support, Duncan Martin & TENET (ZA). Future: work with VSNL for India, Julio Ibarra for L. America Also see: ICFA/SCIC Monitoring report: www.slac.stanford.edu/xorg/icfa/icfa-net-paper-jan06/ PingER project: www-iepm.slac.stanford.edu/pinger/ Extra slides:  Extra slides Slide19:  Maroc Wide Area Network MARWAN 2 Network at 34 Mbps for Research and high education 45 Mbps 34 Mbps 2 Mbps Rabat Casablanca Abdeslam Hoummada 80% universities connect Typically 2Mbps connection Monopoly carrier PERN: Network Architecture:  PERN: Network Architecture DRS DRS DRS Karachi Core ATM/Router Islamabad Core ATM/Router Lahore Core ATM/Router 2x2Mbps 2x2Mbps 2x2Mbps LAN Switch LAN Switch Access Router DXX DXX OFS OF Node University University Customer Replica of Kr./Iba International 2MB DXX DXX OFS University University 12 Universities 22 Universities 23 Universities Access Router University International 4MB International 2MB DRS OFS 57 Mbps 65 Mbps 33 Mbps HEC will invest $ 4M in Backbone 3 To 9 Points-of-Presence (Core Nodes) $ 2.4M from HEC to Public Universities for Last Mile Costs Possible Dark Fiber Initiative Many systemic factors: Electricity, Import duties, Skills:  Many systemic factors: Electricity, Import duties, Skills M. Jensen Slide22:  Average Cost $ 11/kbps/Month Satellites vs Terrestrial:  Satellites vs Terrestrial Terrestrial links via SAT3 & SEAMEW (Mediterranean) Terrestrial not available to all within countries PingER min-RTT measurements from S.
