+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.

+around 340MB.

+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.
