It measures the round-trip time for | -| | packet sent from the originating host to a destination | -| | computer that are echoed back to the source. | -| | | -| | 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. | -| | (For example also a Cirros image can be downloaded from | -| | cirros-image_, it includes ping) | -| | | -+--------------+--------------------------------------------------------------+ -|test topology | Ping packets (ICMP protocol's mandatory ECHO_REQUEST | -| | datagram) are sent from host VM to target VM(s) to elicit | -| | ICMP ECHO_RESPONSE. | -| | | -| | For one host VM there can be multiple target VMs. | -| | Host VM and target VM(s) can be on same or different compute | -| | blades. | -| | | -+--------------+--------------------------------------------------------------+ -|configuration | file: opnfv_yardstick_tc002.yaml | -| | | -| | Packet size 100 bytes. Test duration 60 seconds. | -| | One ping each 10 seconds. Test is iterated two times. | -| | SLA RTT is set to maximum 10 ms. | -| | | -+--------------+--------------------------------------------------------------+ -|applicability | This test case can be configured with different: | -| | | -| | * packet sizes; | -| | * burst sizes; | -| | * ping intervals; | -| | * test durations; | -| | * test iterations. | -| | | -| | Default values exist. | -| | | -| | 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. | -| | | -+--------------+--------------------------------------------------------------+ -|usability | This test case is one of Yardstick's generic test. Thus it | -| | is runnable on most of the scenarios. | -| | | -+--------------+--------------------------------------------------------------+ -|references | Ping_ | -| | | -| | ETSI-NFV-TST001 | -| | | -+--------------+--------------------------------------------------------------+ -|pre-test | The test case image (cirros-image) needs to be installed | -|conditions | into Glance with ping included in it. | -| | | -| | No POD specific requirements have been identified. | -| | | -+--------------+--------------------------------------------------------------+ -|test sequence | description and expected result | -| | | -+--------------+--------------------------------------------------------------+ -|step 1 | Two host VMs are booted, as server and client. | -| | | -+--------------+--------------------------------------------------------------+ -|step 2 | Yardstick is connected with the server VM by using ssh. | -| | 'ping_benchmark' bash script is copyied from Jump Host to | -| | the server VM via the ssh tunnel. | -| | | -+--------------+--------------------------------------------------------------+ -|step 3 | Ping is invoked. Ping packets are sent from server VM to | -| | client VM. RTT results are calculated and checked against | -| | the SLA.
