|test case id | OPNFV_YARDSTICK_TC009_NW PERF, Packet loss |
| | |
+--------------+--------------------------------------------------------------+
|metric | Number of flows, packets lost and throughput |
| | |
+--------------+--------------------------------------------------------------+
|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 VMs 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 ans similar shall be stored for comparison reasons and|
| | product evolution understanding between different OPNFV |
| | versions and/or configurations. |
| | |
+--------------+--------------------------------------------------------------+
|configuration | file: opnfv_yardstick_tc009.yaml |
| | |
| | Packet size: 64 bytes |
| | |
| | Number of ports: 1, 10, 50, 100, 500 and 1000. The amount of |
| | configured ports map from 2 up to 1001000 flows, |
| | respectively. Each port amount is run ten times, for 20 |
| | seconds each. Then the next port_amount is run, and so on. |
| | |
| | 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 Docker |
| | image. |
| | As an example see the /yardstick/tools/ directory for how |
| | to generate a Linux image with pktgen included.) |

+--------------+--------------------------------------------------------------+
|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 loose, 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. |
| | |
