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
• Scalable traffic generation, able to emulate networks in the order of thousands of switches
• Unification of different stress tests, see below:
  • SouthBound idle switch scalability (with MT-Cbench and Mininet)
  • SouthBound active switch scalability (with MT-Cbench)
  • SouthBound active switch stability (with MT-Cbench)
  • Northbound flow scalablity
• Comprehensive reporting and configurable plotting

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