++--------------+--------------------------------------------------------------+
+|metric | RTT, Round Trip Time |
+| | |
++--------------+--------------------------------------------------------------+
+|test purpose | To do a basic verification that network latency is within |
+| | acceptable boundaries when packets travel between hosts |
+| | located on same or different compute blades. |
+| | The purpose is also to be able to spot trends. Test results, |
+| | graphs and similar shall be stored for comparison reasons and|
+| | product evolution understanding between different OPNFV |
+| | versions and/or configurations. |
+| | |
++--------------+--------------------------------------------------------------+
+|configuration | file: opnfv_yardstick_tc002.yaml |
+| | |
+| | Packet size 100 bytes. Total test duration 600 seconds. |
+| | One ping each 10 seconds. SLA RTT is set to maximum 10 ms. |
+| | |
++--------------+--------------------------------------------------------------+
+|test tool | ping |
+| | |
+| | Ping is normally part of any Linux distribution, hence it |
+| | doesn't need to be installed. It is also part of the |
+| | Yardstick Docker image. |
+| | (For example also a Cirros image can be downloaded from |
+| | cirros-image_, it includes ping) |
+| | |

++--------------+--------------------------------------------------------------+
+|applicability | Test case can be configured with different packet sizes, |
+| | burst sizes, ping intervals and test duration. |
+| | SLA is optional. The SLA in this test case serves as an |
+| | example. Considerably lower RTT is expected, and |
+| | also normal to achieve in balanced L2 environments. However, |
+| | to cover most configurations, both bare metal and fully |
+| | virtualized ones, this value should be possible to achieve |
+| | and acceptable for black box testing. Many real time |
+| | applications start to suffer badly if the RTT time is higher |
+| | than this. Some may suffer bad also close to this RTT, while |
+| | others may not suffer at all. It is a compromise that may |
+| | have to be tuned for different configuration purposes. |
+| | |
++--------------+--------------------------------------------------------------+
+|pre-test | The test case image needs to be installed into Glance |
+|conditions | with ping included in it. |
+| | |
+| | No POD specific requirements have been identified. |
+| | |
++--------------+--------------------------------------------------------------+
+|test sequence | description and expected result |
+| | |
++--------------+--------------------------------------------------------------+
+|step 1 | The hosts are installed, as server and client. Ping is |
+| | invoked and logs are produced and stored. |
+| | |
+| | Result: Logs are stored. |
+| | |
++--------------+--------------------------------------------------------------+
+|test verdict | Test should not PASS if any RTT is above the optional SLA |
+| | value, or if there is a test case execution problem. |
+| | |
