Total test duration 600 seconds. | +| | One ping each 10 seconds. SLA RTT is set to maximum 10 ms. | +| | | ++--------------+--------------------------------------------------------------+ +|test tool | ping | +| | | +| | Ping is normally part of any Linux distribution, hence it | +| | doesn't need to be installed. It is also part of the | +| | Yardstick Docker image. | +| | | ++--------------+--------------------------------------------------------------+ +|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 | Each pod node must have ping included in it. | +|conditions | | +| | | ++--------------+--------------------------------------------------------------+ +|test sequence | description and expected result | +| | | ++--------------+--------------------------------------------------------------+ +|step 1 | The pod is available. Two nodes as server and client. | +| | Ping is invoked and logs are produced and stored. | +| | | +| | Result: Logs are stored. | +| | | ++--------------+--------------------------------------------------------------+ +|test verdict | Test should not PASS if any RTT is above the optional SLA | +| | value, or if there is a test case execution problem. | +| | | ++--------------+--------------------------------------------------------------+ |
