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_tc002.yaml | +| | | +| | Packet size 100 bytes.

It is also part of the | +| | Yardstick Docker image. | +| | (For example also a Cirros image can be downloaded from | +| | https://download.cirros-cloud.net, it includes ping) | ++--------------+--------------------------------------------------------------+ +|references | Ping man page | +| | | +| | ETSI-NFV-TST001 | ++--------------+--------------------------------------------------------------+ +|applicability | Test case can be configured with different packet sizes, | +| | burst sizes, ping intervals and test duration. | +| | SLA is optional. The SLA in this test case serves as an | +| | example. Considerably lower RTT is expected, and | +| | also normal to achieve in balanced L2 environments. However, | +| | to cover most configurations, both bare metal and fully | +| | virtualized ones, this value should be possible to achieve | +| | and acceptable for black box testing. Many real time | +| | applications start to suffer badly if the RTT time is higher | +| | than this. Some may suffer bad also close to this RTT, while | +| | others may not suffer at all. It is a compromise that may | +| | have to be tuned for different configuration purposes. | ++--------------+--------------------------------------------------------------+ +|pre-test | The test case image needs to be installed into Glance | +|conditions | with ping included in it. | +| | | +| | No POD specific requirements have been identified. | ++--------------+------+----------------------------------+--------------------+ +|test sequence | step | description | result | +| +------+----------------------------------+--------------------+ +| | 1 | The hosts are installed, as | Logs are stored | +| | | server and client.
