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.
