OpenFlow 1.3 for OpenWRT

Following the steps of Pantou, which turns OpenWrt router into OpenFlow switches, we developed a version using our OpenFlow 1.3 software switch, enabling to test the most recent version of the protocol on a real device, for a low cost.

We build images for the TP-LINK TL-WR1043ND. If you have interest on build for other devices and want to share it, please contact us, so we could keep an images repository.

Pre-compiled image

If you do not want to build the code you can download pre-compiled images from

Build instructions

If you want to build from sources, follow the instructions below. (It will be very similar to the Pantou page).

Note: In the following steps we assume your working directory is ~/openwrt.

Install dependencies.

apt-get install build-essential binutils flex bison autoconf gettext texinfo sharutils \
            subversion libncurses5-dev ncurses-term zlib1g-dev gawk

Download and prepare the packages.

cd ~/openwrt
svn co svn://svn.openwrt.org/openwrt/branches/backfire
cd backfire
./scripts/feeds update -a
./scripts/feeds install -a

Select the packages and build system
