Network measurement

Massive amounts of data can be readily captured in network traces, and can be analysed in many different ways to discover how networks really operate. This has benefits for network planning (when is more capacity needed?), for improving quality of service (why are users seeing poor performance?), and for security analysis (where did all that unwanted traffic come from?).

One example of recent work is here.
