Introduction

What does Gont do?

• Software-defined virtual networking for testing
• Define hosts, switches, routers in a single host
• Reentrancy
• Reproducibility
• Inspired by Mininet

Mininet

"Mininet creates a realistic virtual network, running real kernel, switch and application code, on a single machine (VM, cloud or native)"

-- mininet.org

• Written in Python 2
• Lacking active maintainer
• Focus on SDN: OpenFlow controllers
• No SSL cert on homepage?!

→ We need something better

Why?

• Describe network topologies quickly in code
• Automate construction of complex topologies
• Unit / CI testing
• Parallel test execution
• Example use-cases
  • VPN / network tools development
  • SDN Openflow controller development
  • cunīcu: zeroconf • p2p • mesh • vpn agent (cunīcu)
