Internet NREN performance from U.S. to world at turn of century

Introduction
At the end of the milennium the
PingER project was monitoring,
from 28 monitoring sites in 14 countries, over
500 host in over 70 countries with over 2000 monitoring site remote site
pairs. Below we show the performance of the connections to the countries
as seen from the U.S. and measured by the PingER project.
The results are shown by maps of the
various areas of the world.
Each map:
- Colors grey countries that have collaborators in the major HENP
experiments (Atlas, BaBar, Belle, CDF, CMS, D0, RHIC and ZEUS);
- Colors white countries which have sites that are monitored but the country
does not have an identified major HENP experiment collaborator site.
- Colors green countries which are not monitored and which do not
have an identified major HENP experiment collaborator site.
For each of the monitored countries there is a bar chart identifying the
major performance characteristics of the country as seen from the U.S.
The major performance characteristics are shown for the month of
December 1999. The values are medians for all the sites in the country.
To help identify the magnitudes to be associated with the
bars, the values of the bars are labelled for some countries.
Also identified on the maps are the
monitoring sites
as small blue
circles, and the
beacon sites
as red stars. Also the names of the
countries are identified.
