Load Balancer Sample Application
================================
Compiling the Application
-------------------------
-The sequence of steps used to build the application is:
+To compile the sample application see :doc:`compiling`.
-#. Export the required environment variables:
-
- .. code-block:: console
-
- export RTE_SDK=<Path to the DPDK installation folder>
- export RTE_TARGET=x86_64-native-linuxapp-gcc
-
-#. Build the application executable file:
-
- .. code-block:: console
-
- cd ${RTE_SDK}/examples/load_balancer make
-
- For more details on how to build the DPDK libraries and sample applications,
- please refer to the *DPDK Getting Started Guide.*
+The application is located in the ``load_balancer`` sub-directory.
Running the Application
-----------------------
.. code-block:: console
- ./load_balancer -c 0xf8 -n 4 -- --rx "(0,0,3),(1,0,3)" --tx "(0,3),(1,3)" --w "4,5,6,7" --lpm "1.0.0.0/24=>0; 1.0.1.0/24=>1;" --pos-lb 29
+ ./load_balancer -l 3-7 -n 4 -- --rx "(0,0,3),(1,0,3)" --tx "(0,3),(1,3)" --w "4,5,6,7" --lpm "1.0.0.0/24=>0; 1.0.1.0/24=>1;" --pos-lb 29
There is a single I/O lcore (lcore 3) that handles RX and TX for two NIC ports (ports 0 and 1) that
handles packets to/from four worker lcores (lcores 4, 5, 6 and 7) that
