- Small: 10K lines of code for a 1MB stand-alone executable.
- Efficient: Kernel-bypass Ethernet device drivers plus Linux/KVM vhost networking.
- Extensible: Imagine redesigning Cisco IOS in the style of Emacs.
We are building a Network Virtualization solution as part of Snabb Switch:
- Software-defined overlay networks based on STT tunnels.
- Predictable performance and well-controlled overload behavior.
- Integration with OpenStack Quantum Networking.
Snabb Switch is also suitable as the foundation for building network appliances such as firewalls and routers. You are welcome to build both free and commercial products with Snabb Switch under the terms of the Apache License 2.0.
You can run Snabb Switch on your own machine or via SSH to our Snabb Lab.
$ git clone --recursive git@github.com:SnabbCo/snabbswitch.git
$ cd snabbswitch; make # Builds LuaJIT in under 1 minute and snabbswitch in under 1 second
$ sudo src/snabbswitch -l selftest # Run builtin test routines on the available hardwareSee Hacking for more details.
We are hacking like crazy. I/O is mostly already there and switching mostly is not. Jump in and help!
