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_tc038.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 ten times, for 20 | +| | seconds each. Then the next port_amount is run, and so on. | +| | | +| | During the test CPU load 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.
