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 make menuconfig

####Check for packages dependencies and build make prereq make

####Add OpenFlow git clone https://github.com/CPqD/openflow-openwrt.git cd ~/openwrt/backfire/packages/ ln -s ~/openwrt/openflow-openwrt/openflow-1.3/ cd ~/ofwrt/backfire/ ln -s ~/openwrt/openflow-openwrt/openflow-1.3/files cd ~/ofwrt/ make menuconfig

Select the OpenFlow package under Network and build the image. make kernel_menuconfig make
