# Data Channel Offload: non-Linux platforms

## Windows
A kernel module has also been developed for Windows, namely *ovpn-dco-win*.

It is a device driver implemented in kernelspace that substitutes all previous drivers used by OpenVPN (i.e. tap-windows6, wintun, etc..). Differently from the other drivers, ovpn-dco-win uses the Windows Kernel API to also implement crypto operations, thus allowing the driver to process data packets entirely in kernelspace, similarly to ovpn-dco for Linux.

The ovpn-dco-win source code is currently available at the following repository: https://github.com/OpenVPN/ovpn-dco-win

## FreeBSD
The FreeBSD community has shown great interest for the DCO model and so they also implemented a FreeBSD kernel module.
It is expected to be a drop-in replacement for ovpn-dco on Linux, thus implementing the same feature set.

The originally proposed change (now merged) can be found at: https://reviews.freebsd.org/D34340

DCO will be shipped starting with FreeBSD 14 (to be released yet).
