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.) | +| | | ++--------------+--------------------------------------------------------------+ +|references | pktgen_ | +| | | +| | ETSI-NFV-TST001 | +| | | ++--------------+--------------------------------------------------------------+ +|applicability | Test can be configured with different packet sizes, amount | +| | of flows and test duration.
