Jozef Urbanovský

LNST (Linux Network Stack Test) is a Python framework for writing multihost network tests. It allows user to automatically map the network, configure it to desired state, measure network performance and evaluate results.

During the presentation we'll show how basic tests can be written and how the same framework is utilized in more complex scenarios where we test the Linux kernel, looking for performance regressions.

Finally we'll shortly discuss how LNST is used at Red Hat with other tools to create an automated pipeline that tests and reports results for kernel and other package candidate builds.
