What we do
We conduct research on large-scale distributed systems and networking. Our approach is mainly experimental, focusing on the design, deployment and evaluation of systems that people use. Much of our work is guided by the unique perspective provided by devices at the edge of the Internet and captured through our users/collaborators who adopt and use our software. We are driven by a desire to provide solutions to real network and systems problems, while we also take pleasure in the scientific and engineering contributions that we make.

Mobile Network Performance and Content Delivery - Part 2
Most Content Delivery Networks (CDNs) attempt to pick the closest replcia server to your location. We see large inefficiencies in replica selection for cellular networks, with remote Public DNS resolvers retrieving better replicas a significant fraction of time.

Mobile Network Performance and Content Delivery - Part 1
Web performance is determined by more than just SpeedTest's reported “Network Performance”. The video you watch, the DNS service you choose, and the server it's delivered from have a much larger impact on your perceived performance.

Comparing broadband services on users' terms
Paying for higher download speeds may not improve your web performance; it also depends on the pages you visit.
