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

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
worlds Internet connected population

• Remote hosts
• gt105 countries
• 560 sites
• 880 hosts
• 3650pairs

Dec-2003

• In 2001 lt20 of the worlds population had Good
  or Acceptable Loss performance

• BUT by December 2003It had improved to 77

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
Many institutes in developing world have less
performance than a household in N. America or
Europe
5
Within Developing Regions

• In 80s many Eu countries connected via US
• Today often 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,
• Route goes via England!!!!
• Takes longer to go few miles than to SLAC!

• Doubles international link traffic, increases
  delays, increases dependence on others
• Within a region can be big differences between
  sites/countries, due to service providers

Loss to Africa (example of variability)

Technology Achievement Index (TAI)

• TAI captures how well a country is creating and
  diffusing technology and building a human skills
  base.
• TAI from UNDP hdr.undp.org/reports/global/2001/en/

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)
