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.

It is also part of the | | | Yardstick Glance image. | | | (For example also a cirros_ image can be downloaded, it | | | includes ping) | | | | | | mpstat | | | | | | (Mpstat is not always part of a Linux distribution, hence it | | | needs to be installed.
