+Packet Ordering
+===============
+
+This document provides test plan for benchmarking of the Packet Ordering
+sample application. This is a simple example app featuring packet processing
+using Intel® Data Plane Development Kit (Intel® DPDK) based on a sliding window
+using a sequence number for the packet and a reorder queue.
+
+
+Prerequisites
+-------------------
+
+1x Intel® 82599 (Niantic) NICs (1x 10GbE full duplex optical ports per NIC)
+plugged into the available PCIe Gen2 8-lane slot.
+
+Test Case: Packet ordering at different rates
+=============================================
+
+The test case will send packets from the external traffic generator through
+the sample application which will forward them back to the source port.
+Each packet will have a sequential number which could be used to judge
+if a packet is in the right order.
+Different traffic rates will be tested. The rate will go from 10% to 100%
+with 10% steps.
+
+The results will be presented as a table with the following values:
+
+Reordering: indicate if reorder the traffic.
+
+Mask: used CPU core mask.
+
+Rate: transmission rate.
+
+Sent: number of frames sent from the traffic generator.
+
+Received: number of frames received back.
+
+Captured: number of frames captured.
+
+Reordered ratio: ratio between out of order packets and total sent packets.
+
++------------+------+------+--------+----------+----------+---------------+
+| Reordering | Mask | Rate | Sent | Received | Captured | Reorder ratio |
++============+======+======+========+==========+==========+===============+
+| Yes | 0xaa | 10 | | | | |
++------------+------+------+--------+----------+----------+---------------+
+| Yes | 0xf | 10 | | | | |
++------------+------+------+--------+----------+----------+---------------+
+| No | 0xaa | 10 | | | | |
++------------+------+------+--------+----------+----------+---------------+
+| No | 0xf | 10 | | | | |
++------------+------+------+--------+----------+----------+---------------+
+
+Run the app with below sample command::
+
+ ./examples/packet_ordering/build/packet_ordering -c coremask -- -p portmask
