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_tc001.yaml | +| | | +| | Packet size: 60 bytes | +| | Number of ports: 10, 50, 100, 500 and 1000, where each | +| | runs for 20 seconds. The whole sequence is run | +| | twice. The client and server are distributed on different HW.| +| | For SLA max_ppm is set to 1000. The amount of configured | +| | ports map to between 110 up to 1001000 flows, respectively. | +| | | ++--------------+--------------------------------------------------------------+ +|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.
