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_tc008.yaml | +| | | +| | Packet size: 64, 128, 256, 512, 1024, 1280 and 1518 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 packet_size/port_amount combination is run| +| | ten times, for 20 seconds each. Then the next | +| | packet_size/port_amount combination 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.) | +| | | ++--------------+--------------------------------------------------------------+ +|references | pktgen_ | +| | | +| | ETSI-NFV-TST001 | +| | | ++--------------+--------------------------------------------------------------+ +|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. | +| | | ++--------------+--------------------------------------------------------------+ |
