Kathará Framework

Welcome to the Kathará Framework on GitHub! Kathará is a network emulator designed for networking education, research and testing. Our aim is to provide a flexible and practical environment for testing, experimenting, and learning about computer networks.

Projects

Core Framework and Tools

  • Kathará: The core framework that powers network emulation.
  • Docker Images: Docker images that provide specialized suites for different network scenarios.
  • Kathará Labs: Collection of the official Kathará network scenarios, tutorials and exercises.
  • Kathará Lab Checker: Tool to automatically check Kathará network scenarios based on a configuration file.
  • Kathará Network Plugin: Docker Network Plugin used by Kathará to create pure L2 networks.
  • Netkit Lab Generator: A tool to configure a Kathará or a Netkit lab and generate all the files you need and the topology graph.

IXP Solutions

  • IXP Digital Twin: A tool for generating an emulation-based digital twin for Internet Exchange Points (IXPs), enabling IXPs to test and validate route server configurations in a controlled environment.
  • IXP Quarantine Dashboard: A GUI that allows customers to run quarantine checks of the IXP Digital Twin for configuration validation directly from a browser, showing check statuses and providing guidance for fixing issues.
