+Prerequisites
+=============
+One 10Gb Ethernet port of the DUT is directly connected and link is up.
+
+===================
+Packet Distributor
+===================
+The DPDK Packet Distributor library is a library designed to be used for 
+dynamic load balancing of traffic while supporting single packet at a 
+time operation. When using this library, the logical cores in use are to 
+be considered in two roles: firstly a distributor lcore, which is 
+responsible for load balancing or distributing packets, and a set of 
+worker lcores which are responsible for receiving the packets from the 
+distributor and operating on them. 
+
+This is the test plan for Packet Distributor unit test.
+
+This section explains how to run the unit tests for distributor.
+The test can be launched independently using the command line interface. 
+This test is implemented as a linuxapp environment application.
+
+The complete test suite is launched automatically using a python-expect
+script (launched using ``make test``) that sends commands to
+the application and checks the results. A test report is displayed on
+stdout.
+
+The final output of the test will be average cycles of IO used per packet.
+
+The steps to run the unit test manually are as follow::
+
+  # make -C ./app/test/
+  # ./app/test/test -n 1 -c ffff
+  RTE>> distributor_autotest
+
+suppose we test 1 distributor core and n worker cores::
+
+number of cores will be  n+1
+
+===============================================
+Test Case: 1 distributor core and 1 worker core
+===============================================
+number of cores is 2::
+
+    ./app/test/test -n 1 -c 0xC
+
+================================================
+Test Case: 1 distributor core and 4 worker cores
+================================================
+number of cores is 5::
+
+    ./app/test/test -n 1 -c 0x3e
+
+================================================
+Test Case: 1 distributor core and 8 worker cores
+================================================
+number of cores is 9::
+
+    ./app/test/test -n 1 -c 0x3fe
+
+================================================
+Test Case: 1 distributor core and 5 worker cores
+================================================
+number of cores is 6::
+
+    ./app/test/test -n 1 -c 0x7e
+================================================
+Test Case: 1 distributor core and 10 worker core
+================================================
+number of cores is 11::
+
+    ./app/test/test -n 1 -c 0xffe
