TrendsS.E. Europe, Russia: catching upLatin Am., Mid East, China: keeping upIndia, Africa: falling behind

C. Asia, Russia, S.E. Europe, L. America, M. East, China: 4-5 yrs behind

India, Africa: 7 yrs behind

Many institutes in developing world have less performance than a household in N. America or Europe

Within Developing Regions

• Not unusual for communications within developing regions to go via developed region, e.g.– Rio to Sao Paola goes directly within Brazil – But Rio to Buenos Aires goes via Florida

• And…–NIIT – NSC (Rawalpindi – Islamabad) few miles apart,

•No peering in Pakistan, can this be changed?•Route goes via England!!!!•Takes longer to go few miles than to SLAC!

• Also within a region can be big differences between sites/countries, due to service providers

Technology Achievement Index (TAI)

• TAI captures how well a country is creating and diffusing technology and building a human skills base.

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)
