Re: [gaia] Heterogeneity in network capacity: growing?

[Nick Feamster <[e-mail]>]

Folks may also be interested in the BISmark project:
http://projectbismark.net/

We measure throughput from hundreds of home networks around the world in about 30 countries.  All of that data is available at http://uploads.projectbismark.net/

We also have a mobile throughput application:
http://play.google.com/store/apps/details?id=com.num

We’ve used these to study throughput in the US, South Africa, and Pakistan. In South Africa and Pakistan, we looked at both fixed line and mobile throughput.  Here are the relevant papers:
