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 and similar shall be stored for | +| | comparison reasons and product evolution understanding | +| | between different OPNFV versions and/or configurations. | +| | | ++--------------+--------------------------------------------------------------+ +|configuration | file: opnfv_yardstick_tc070.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 two times, for 20 | +| | seconds each. Then the next port_amount is run, and so on. | +| | During the test Memory Utilization 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 part of the Yardstick Glance | +| | image. | +| | (As an example see the /yardstick/tools/ directory for how | +| | to generate a Linux image with pktgen included.) | +| | | +| | ping | +| | | +| | Ping is normally part of any Linux distribution, hence it | +| | doesn't need to be installed. It is also part of the | +| | Yardstick Glance image. | +| | (For example also a cirros_ image can be downloaded, it | +| | includes ping) | +| | | +| | free | +| | | +| | free provides information about unused and used memory and | +| | swap space on any computer running Linux or another Unix-like| +| | operating system. | +| | free is normally part of a Linux distribution, hence it | +| | doesn't needs to be installed. | +| | | ++--------------+--------------------------------------------------------------+ +|references | Ping and free man pages | +| | | +| | 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 lose, 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. | +| | | ++--------------+--------------------------------------------------------------+ |
