Welcome to the home of Flent

Flent is a network benchmarking tool which allows you to:

• Easily run network tests composing multiple well-known benchmarking tools into aggregate, repeatable test runs.
• Explore your test data through the interactive GUI and extensive plotting capabilities.
• Combine and aggregate data series and produce publication quality graphs.
• Capture metadata from local and remote hosts and store it along with the plot data.
• Collect secondary data series such as CPU usage, WiFi, qdisc and TCP socket statistics and plot it with the main dataset.
• Specify batch experiment runs to completely automate your testing regime.

Flent is written in Python and wraps well-known network benchmarking tools (such as netperf and iperf) into aggregate, repeatable tests, such as a number of tests for Bufferbloat.

There's a short paper (pdf) and a blog post describing some of the design goals of Flent.
