End to end Internet Performance today Prepared by Les Cottrell, SLAC, for the Extending the Reach of Advanced Networking: Special International Workshop Arlington, VA., April 22, 2004 www.slac.stanford.edu/grp/scs/net/talk03/i2-overview-apr04.ppt PingER is arguably the most extensive set of measurements of the end-to-end performance of the Internet going back almost ten years. Measurements are available from over 30 sites in 13 countries to sites in over 100 countries. We will use the PingER results to: demonstrate how the Internet performance to the regions of the world has evolved over the last 9 years; identify regions that have poor connectivity, how far they are behind the developed world and whether they are catching up or falling further behind; and illustrate the correlation between the UN Technology Achievement Index and Internet performance. Partially funded by DOE/MICS Field Work Proposal on Internet End-to-end Performance Monitoring (IEPM), also supported by IUPAP

Countries Monitored Monitor site Remote site Monitoring hosts 35 hosts 13 Countries Countries monitored contain over 90% of the world’s Internet connected population Need >1 host/country to reduce anomalies. Remote hosts >105 countries 560 sites 880 hosts 3650pairs

Loss to world from US Loss Rate < 0.1 to 1 % 1 to 2.5 % 2.5 to 5 % > 12 % 2001 Dec-2003 In 2001 <20% of the world’s population had Good or Acceptable Loss performance BUT by December 2003 It had improved to 77% Spreadsheet: v:Groups\scs\networking\netdev\tai-dec03.xls

Trends C. Asia, Russia, S.E. Europe, L. America, M. East, China: 4-6 yrs behind India, Africa: 7 yrs behind S.E. Europe, Russia: catching up Latin Am., Mid East, China: keeping up India, Africa: falling behind Spreadsheet \cottrell\iepm\esnet-to-all-longterm.xls CERN data only goes back to Aug-01. It confirms S.E. Europe & Russia are catching up, and India & Africa are falling behind Note for Africa only one host in Uganda. Actually have been adding hosts 5 countries), but there is considerable disparity in performance so as add hosts from less developed countries the aggregate performance measured to Africa is dropping! Ghana, Nigeria and Uganda are all satellite links with 800-1100ms RTTs. The losses to Ghana & Nigeria are 8-12% while to Uganda they are 1-3%. The routes are different. The route from SLAC to Ghana uses ESnet-Worldcom-UUNET, Nigeria goes CalREN-Qwest-Teiianet-New Skies satellite, Uganda goes Esnet-Level3-Intelsat. For both Ghana and Nigeria there are no losses (for 100 pings) until the last hop when over 40 of 100 packets were lost. For Uganda the losses (3 in 100 packets) also occur at the last hop.

TAI aims to capture how well a country is creating and diffusing technology and building a human skill base TAI includes the following dimensions: Creation of technology (e.g. patents, royalty receipts); diffusion of recent innovations (Internet hosts/capita, high & medium tech exports as share of all exports); Diffusion of old innovations (log phones/capita, log of electric consumption/capita); Human skills (mean years of schooling, gross enrollment in tertiary level in science, math & engineering)

Summary Performance from U.S. & Europe is improving all over Performance to developed countries are orders of magnitude better than to developing countries Poorer regions 5-10 years behind Poorest regions Africa, Caucasus, Central & S. Asia Some regions are: catching up (SE Europe, Russia), keeping up (Latin America, Mid East, China), falling further behind (e.g. India, Africa)
