We are quantifying the extent and magnitude of the Digital Divide by measuring the gap in Internet performance for developed countries and developing countries.
The monitor will show a map of the
world with ping round trip times (click
for real live demo) to sites
in various regions of the world on both sides of the Digital Divide to
illustrate the performance in real-time as seen from SC03. We will also show
long-term graphs going back 8 years that illustrate many developing regions
have factors of 10-50 times worse performance than developed regions.
Some regions such as Latin America & S.E. Europe are catching up to the
exponential growth of the developed nations, others such as China, Russia
and the Indian sub-continent are 5 or more years behind but keeping up,
and others such as Africa are 10 years behind and falling further behind.
This is a challenge to Non Government Organizations/Agencies working on,
or financing projects to bridge the Digital Divide. We will have handouts
academic paper on the work in progress and on the
PingER measurement project.
Non-interactive. Needs a screen. On fabric.
Available Bandwidth Estimation (ABwE) showing
maps with real-time time series of
bandwidth to various high-performance (10-622Mbits/s) sites in N. America,
Europe and Eastern Asia.
Can be unattended, does not need interaction.
High performance network and application end-to-end performance monitoring based on IEPM-BW. We hope to be able to demonstrate the performance of various file transfer mechanisms such as bbftp, bbcp, and GridFTP.
