OpenBSD has a built in OpenFlow switch. It doesn’t support FAUCET in released code, but there is experimental support with a kernel patch. https://github.com/anarkiwi/faucet/blob/openbsd/docs/vendors/openbsd/README_OpenBSD.rst

Every now and then, I’m asked – how can switch vendor add support for FAUCET? The best way to understand how FAUCET uses OpenFlow, is to use the test suite. However, some current FAUCET vendors and developers have been kind enough to share their experiences about how to make FAUCET run on hardware: Allied Telesis …

If you have a FAUCET stack network, with potentially many switches, it would sure be nice to have a way to be able to mirror any port on any switch, and have that traffic show up on one port on one switch. You can do this, across multiple vendor switches, by combining several FAUCET features …

This rather ugly, but dramatically lit little fellow is a passive loopback cable (I connected only two pairs, so it can do only 100MB). Here it is installed in port 11 on this OpenFlow switch. But why? What possible use is this beyond testing that the physical interface works? Some OpenFlow switch implementations are based …

Obligatory XKCD. In this post, I thought it would be efficient to describe my own personal motivations for contributing to SDN generally and FAUCET specifically, and why I personally believe they’re both good things. You could say in the New Zealand vernacular, that these are my “reckons.” I’m responsible solely for them – I do …
