It supports tuning of | -| | various parameters related to timing, buffers and protocols. | -| | The UDP protocols can be used to measure jitter delay. | -| | | -| | (iperf3 is not always part of a Linux distribution, hence it | -| | needs to be installed. It is part of the Yardstick Docker | -| | image. As an example see the /yardstick/tools/ directory for | -| | how to generate a Linux image with pktgen included.) | -| | | -+--------------+--------------------------------------------------------------+ -|test | iperf3 test is invoked between a host VM and a target VM. | -|description | | -| | Jitter calculations are continuously computed by the server, | -| | as specified by RTP in RFC 1889. The client records a 64 bit | -| | second/microsecond timestamp in the packet. The server | -| | computes the relative transit time as (server's receive time | -| | - client's send time). The client's and server's clocks do | -| | not need to be synchronized; any difference is subtracted | -| | outin the jitter calculation. Jitter is the smoothed mean of | -| | differences between consecutive transit times. | -| | | -+--------------+--------------------------------------------------------------+ -|configuration | File: opnfv_yardstick_tc011.yaml | -| | | -| | * options: | -| | protocol: udp # The protocol used by iperf3 tools | -| | bandwidth: 20m # It will send the given number of packets | -| | without pausing | -| | * runner: | -| | duration: 30 # Total test duration 30 seconds. | -| | | -| | * SLA (optional): | -| | jitter: 10 (ms) # The maximum amount of jitter that is | -| | accepted. | -| | | -+--------------+--------------------------------------------------------------+ -|applicability | Test can be configured with different: | -| | | -| | * bandwidth: Test case can be configured with different | -| | bandwidth. | -| | | -| | * duration: The test duration can be configured. | -| | | -| | * jitter: SLA is optional. The SLA in this test case | -| | serves as an example. | -| | | -+--------------+--------------------------------------------------------------+ -|usability | This test case is one of Yardstick's generic test. Thus it | -| | is runnable on most of the scenarios. | -| | | -+--------------+--------------------------------------------------------------+ -|references | iperf3_ | -| | | -| | ETSI-NFV-TST001 | -| | | -+--------------+--------------------------------------------------------------+ -|pre-test | The test case image needs to be installed into Glance | -|conditions | with iperf3 included in the image. | -| | | -| | No POD specific requirements have been identified. | -| | | -+--------------+--------------------------------------------------------------+ -|test sequence | description and expected result | -| | | -+--------------+--------------------------------------------------------------+ -|step 1 | Two host VMs with iperf3 installed are booted, as server and | -| | client. | -| | | -+--------------+--------------------------------------------------------------+ -|step 2 | Yardstick is connected with the host VM by using ssh. | -| | A iperf3 server is started on the server VM via the ssh | -| | tunnel. | -| | | -+--------------+--------------------------------------------------------------+ -|step 3 | iperf3 benchmark is invoked.
