Kathará – lightweight network emulation system

Kathará is a lightweight network emulation system based on Docker containers.

It can be helpful in showing interactive demos/lessons, testing production networks in a sandbox environment, or developing new network protocols.

Each network device is emulated by a container. Virtual network devices are interconnected by virtual L2 LANs.

This is free and open source software.

Key Features

  • Each container can potentially run a different Docker image.
  • Built-in images include Quagga, FRRouting, Bind, P4, OpenVSwitch, and more, but you can also use your own container images.
  • Simplifies the creation of complex networks using the concept of network scenario: a directory containing a file with the network topology, and, for each device, files and folders containing the configuration of that device.
  • Emulates network scenarios using either Docker or Kubernetes as backend virtualization system.
  • Cross-platform support – runs under Linux (x86_64 and ARM64), macOS (x86_64 and ARM64), and Windows (x86_64 and ARM64).

Hi Steve. I think the GH link is wrong.
