-Overview of test results
-------------------------
-
-See Grafana_ for viewing test result metrics for each respective test case. It
-is possible to chose which specific scenarios to look at, and then to zoom in
-on the details of each run test scenario as well.
-
-All of the test case results below are based on 4 scenario test
-runs, each run on the Ericsson POD2_ or LF POD2_ between August 24 and 30 in
-2016.
-
-TC002
------
-The round-trip-time (RTT) between 2 VMs on different blades is measured using
-ping. Most test run measurements result on average between 0.44 and 0.75 ms.
-A few runs start with a 0.65 - 0.68 ms RTT spike (This could be because of
-normal ARP handling). One test run has a greater RTT spike of 1.49 ms.
-To be able to draw conclusions more runs should be made. SLA set to 10 ms.
-The SLA value is used as a reference, it has not been defined by OPNFV.
-
-TC005
------
-The IO read bandwidth looks similar between different dates, with an
-average between approx. 92 and 204 MB/s. Within each test run the results
-vary, with a minimum 2 MB/s and maximum 819 MB/s on the totality. Most runs
-have a minimum BW of 3 MB/s (one run at 2 MB/s). The maximum BW varies more in
-absolute numbers between the dates, between 238 and 819 MB/s.
-SLA set to 400 MB/s. The SLA value is used as a reference, it has not been
-defined by OPNFV.
-
-TC010
------
-The measurements for memory latency are similar between test dates and result
-in approx. 2.07 ns. The variations within each test run are similar, between
-1.41 and 3.53 ns.
-SLA set to 30 ns. The SLA value is used as a reference, it has not been defined
-by OPNFV.
-
-TC011
------
-Packet delay variation between 2 VMs on different blades is measured using
-Iperf3. The reported packet delay variation varies between 0.0051 and 0.0243 ms,
-with an average delay variation between 0.0081 ms and 0.0195 ms.
-
-TC012
------
-Between test dates, the average measurements for memory bandwidth result in
-approx. 13.6 GB/s. Within each test run the results vary more, with a minimal
-BW of 6.09 GB/s and maximum of 16.47 GB/s on the totality.
-SLA set to 15 GB/s. The SLA value is used as a reference, it has not been
-defined by OPNFV.
-
-TC014
------
-The Unixbench processor test run results vary between scores 2316 and 3619,
-one result each date.
-No SLA set.
-
-TC037
------
-The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs
-on different blades are measured when increasing the amount of UDP flows sent
-between the VMs using pktgen as packet generator tool.
-
-Round trip times and packet throughput between VMs can typically be affected by
-the amount of flows set up and result in higher RTT and less PPS throughput.
-
-The RTT results are similar throughout the different test dates and runs at
-approx. 15 ms. Some test runs show an increase with many flows, in the range
-towards 16 to 17 ms. One exception standing out is Feb. 15 where the average
-RTT is stable at approx. 13 ms. The PPS results are not as consistent as the
-RTT results.
-In some test runs when running with less than approx. 10000 flows the PPS
-throughput is normally flatter compared to when running with more flows, after
-which the PPS throughput decreases. Around 20 percent decrease in the worst
-case. For the other test runs there is however no significant change to the PPS
-throughput when the number of flows are increased. In some test runs the PPS
-is also greater with 1000000 flows compared to other test runs where the PPS
-result is less with only 2 flows.
-
-The average PPS throughput in the different runs varies between 414000 and
-452000 PPS. The total amount of packets in each test run is approx. 7500000 to
-8200000 packets. One test run Feb. 15 sticks out with a PPS average of
-558000 and approx. 1100000 packets in total (same as the on mentioned earlier
-for RTT results).
-
-There are lost packets reported in most of the test runs. There is no observed
-correlation between the amount of flows and the amount of lost packets.
-The lost amount of packets normally range between 100 and 1000 per test run,
-but there are spikes in the range of 10000 lost packets as well, and even
-more in a rare cases.
-
-CPU utilization statistics are collected during UDP flows sent between the VMs
-using pktgen as packet generator tool. The average measurements for CPU
-utilization ratio vary between 1% to 2%. The peak of CPU utilization ratio
-appears around 7%.
-
-TC069
------
-Between test dates, the average measurements for memory bandwidth vary between
-22.6 and 29.1 GB/s. Within each test run the results vary more, with a minimal
-BW of 20.0 GB/s and maximum of 29.5 GB/s on the totality.
-SLA set to 6 GB/s. The SLA value is used as a reference, it has not been
-defined by OPNFV.

-Detailed test results
----------------------
-The scenario was run on Ericsson POD2_ and LF POD2_ with:
-Fuel 9.0
-OpenStack Mitaka
-OpenVirtualSwitch 2.5.90
-OpenDayLight Beryllium
-
-Rationale for decisions
------------------------
-Pass
-
-Tests were successfully executed and metrics collected.
-No SLA was verified. To be decided on in next release of OPNFV.
-
-Conclusions and recommendations
--------------------------------
-The pktgen test configuration has a relatively large base effect on RTT in
-TC037 compared to TC002, where there is no background load at all. Approx.
-15 ms compared to approx. 0.5 ms, which is more than a 3000 percentage
-difference in RTT results.
-Especially RTT and throughput come out with better results than for instance
-the *fuel-os-nosdn-nofeature-ha* scenario does. The reason for this should
-probably be further analyzed and understood. Also of interest could be
-to make further analyzes to find patterns and reasons for lost traffic.
-Also of interest could be to see if there are continuous variations where
-some test cases stand out with better or worse results than the general test
-case.
