"The OpenFlow eXtensible DataPath daemon (xDPd) is a multi-platform, multi OF version, open-source datapath built focusing on performance and extensibility."
xDPd can also be considered a framework for building OpenFlow datapath elements, as it is designed to be easily extended with the support of new forwarding devices.
Shipped with all xDPd instances:
- GNU/Linux amd64/x86 user-space with mmap or netmap (gnu-linux). open-source
- GNU/Linux + NetFGPA-10G (netfpga10g). open-source.
- GNU/Linux Intel's DPDK accelerated driver (gnu-linux-dpdk). open-source
Also available:
- Broadcom Triumph2 (bcm).
- Octeon network processors (octeon5650).
- Other: refer to the wiki page for more details
You may want to have a look to the particular README pages of each platform by inspecting:
src/xdpd/drivers/{platform_name}/README
- A modern GNU build-system (autoconf, automake, libtool, ...)
- GNU/Linux and libc development headers (linux-libc-dev and libc6-dev package in Debian/Ubuntu systems)
- pkg-config
- libconfig C++ lib (libconfig++-dev in Debian/Ubuntu systems)
- ROFL libraries installed [1]
- [optional] if you want to run automatic tests (make check), libcunit and libcppunit are required (in libcunit1-dev and libcppunit-dev packages in Debian-like systems).
- [optional] Doxygen to generate the documentation.

Install the dependencies and run:
sh# ./autogen.sh
sh# cd build
sh# ../configure
sh# make
sh# make install
Optionally you can make check for consistency checks. For other platforms different than gnu-linux, please make sure --with-hw-support=platform-name is specified, and that the appropriate README is read (e.g. src/xdpd/drivers/example/README).
Copy the example.cfg:
sh# cd build/src/xdpd
sh# cp src/xdpd/management/plugins/config/example.cfg .
Now edit the configuration. Make sure ports attached to the Logical Switch Instance (LSI) exist in the system.
sh# vi src/xdpd/management/plugins/config/example.cfg
Run xdpd:
sh# ./xdpd -c example.cfg
--with-hw-support=platform-name: Compiles support for the platform-name (platform driver). Default is gnu-linux.
--with-plugins="plugin1...pluginN": Compile with plugin1..pluginN enabled. Default is --with-plugins="config" plugin.
--enable-debug: Compile with debug symbols (-g) and debug output (warning, it may affect performance).
--disable-silent-rules: Enable verbose compilation mode (AM_SILENT_RULES disabled)
xDPd package uses subdir-objects. From 1.4 on, the support of subdir-objects must be explicitly added in AM_INIT_AUTOMAKE() in order to prevent warnings that will abort compilation. However, due to the following bug:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13928
The build system won't work if subdir-objects is added in AM_INIT_AUTOMAKE() for both Automake 1.4 and 1.3.
Currently, in order to compile the package, the suggested strategy is to remove -Werror from AM_INIT_AUTOMAKE() in ALL the configure.ac-s (configure.ac, src/xdpd/drivers/example/configure.ac ...):
diff --git a/configure.ac b/configure.ac
index ccf3f21..96931b9 100644

Note there will be a considerably number of warnings shown. Once bug 13928, 'subdir-objects' will be added as it should be.
You can have a look on:
Documentation can be compiled via make doc. Documentation is generated in build/doc/ folder
