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
• Scalable traffic generation with MT-Cbench and Multinet emulators, able to emulate networks in the order of thousands of switches
• Unification of different stress tests, see below:
  • Switch scalability test with active MT-Cbench switches
  • Switch scalability test with active Multinet switches
  • Switch scalability test with idle MT-Cbench switches
  • Switch scalability test with idle Multinet switches
  • Controller stability test with active MT-Cbench switches
  • Controller stability test with idle Multinet switches
  • Flow scalability test with idle Multinet switches
• Comprehensive reporting and configurable plotting

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