-| | Throughput,Packet Loss |

-+--------------+--------------------------------------------------------------+
-|metric | Number of flows, latency, throughput, Cache Utilization, |
-| | packet loss |
-| | |
-+--------------+--------------------------------------------------------------+
-|test purpose | To evaluate the IaaS network performance with regards to |
-| | flows and throughput, such as if and how different amounts |
-| | of flows matter for the throughput between hosts on different|
-| | compute blades. Typically e.g. the performance of a vSwitch |
-| | depends on the number of flows running through it. Also |
-| | performance of other equipment or entities can depend |
-| | on the number of flows or the packet sizes used. |
-| | 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_tc071.yaml |
-| | |
-| | Packet size: 64 bytes |
-| | Number of ports: 1, 10, 50, 100, 300, 500, 750 and 1000. |
-| | The amount configured ports map from 2 up to 1001000 flows, |
-| | respectively. Each port amount is run two times, for 20 |
-| | seconds each. Then the next port_amount is run, and so on. |
-| | During the test Cache Utilization on both client and server, |
-| | and the network latency between the client and server are |
-| | measured. |
-| | The client and server are distributed on different HW. |
-| | For SLA max_ppm is set to 1000. |
-| | |

-|test tool | pktgen |
-| | |
-| | Pktgen is not always part of a Linux distribution, hence it |
-| | needs to be installed. It is part of the Yardstick Glance |
-| | image. |
-| | (As an example see the /yardstick/tools/ directory for how |
-| | to generate a Linux image with pktgen included.) |
-| | |
-| | ping |
-| | |
-| | Ping is normally part of any Linux distribution, hence it |
-| | doesn't need to be installed. It is also part of the |
-| | Yardstick Glance image. |
-| | (For example also a cirros_ image can be downloaded, it |
-| | includes ping) |
-| | |
-| | cachestat |
-| | |
-| | cachestat is not always part of a Linux distribution, hence |
-| | it needs to be installed. |

-|applicability | Test can be configured with different packet sizes, amount |
-| | of flows and test duration. Default values exist. |
-| | |
-| | SLA (optional): max_ppm: The number of packets per million |
-| | packets sent that are acceptable to lose, not received. |
-| | |
-+--------------+--------------------------------------------------------------+
-|pre-test | The test case image needs to be installed into Glance |
-|conditions | with pktgen 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. pktgen is |
-| | invoked and logs are produced and stored. |
-| | |
-| | Result: Logs are stored. |
-| | |
-+--------------+--------------------------------------------------------------+
-|test verdict | Fails only if SLA is not passed, or if there is a test case |
-| | execution problem. |
