Welcome to the nstat wiki!

Overview

NSTAT is an environment written in Python for easily writing and running SDN controller stress tests in a highly-configurable and modular manner.

Key features in brief:

• Fully automated, end-to-end testing with exhaustive test cases
• Easy and rich configuration system
• Unification of different stress tests:
  • Switch scalability test with idle MT-Cbench and OpenVSwitches topologies (the deployment of these topologies is made with the use of Multinet tool. Multinet is based on mininet API).
  • Switch scalability test with active MT-Cbench switches
  • Controller stability test with active MT-Cbench switches
  • Flow scalability test
• Comprehensive reporting and configurable plotting

For a detailed features list have a look at the features page.
