-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 5 scenario test runs, each run
-on the Intel POD6_ between September 13 and 16 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 1.50 and 1.68 ms.
-Only one test run has reached greatest RTT spike of 2.62 ms, which has
-the smallest RTT of 1.00 ms. The other four runs have no similar spike at all,
-the minimum and average RTTs of which are approx. 1.06 ms and 1.32 ms. SLA set
-to be 10 ms. The SLA value is used as a reference, it has not been defined by
-OPNFV.
-
-TC005
------
-The IO read bandwidth actually refers to the storage throughput, which is
-measured by fio and the greatest IO read bandwidth of the four runs is 175.4
-MB/s. The IO read bandwidth of the four runs looks similar on different four
-days, with an average between 58.1 and 62.0 MB/s, except one on Sep. 14, for
-its maximum storage throughput is only 133.0 MB/s. One of the runs has a
-minimum BW of 497 KM/s and other has a maximum BW of 177.4 MB/s. The SLA of read
-bandwidth sets to be 400 MB/s, which is used as a reference, and it has not
-been defined by OPNFV.
-
-The results of storage IOPS for the five runs look similar with each other. The
-IO read times per second of the five test runs have an average value between
-1.20 K/s and 1.61 K/s, and meanwhile, the minimum result is only 41 times per
-second.
-
-TC010
------
-The tool we use to measure memory read latency is lmbench, which is a series of
-micro benchmarks intended to measure basic operating system and hardware system
-metrics. The memory read latency of the five runs is between 1.146 ns and 1.172
-ns on average. The variations within each test run are quite different, some
-vary from a large range and others have a small change. For example, the
-largest change is on September 13, the memory read latency of which is ranging
-from 1.152 ns to 1.221 ns. However, the results on September 14 change very
-little. The SLA sets to be 30 ns. The SLA value is used as a reference, it has
-not been defined by OPNFV.
-
-TC011
------
-Iperf3 is a tool for evaluating the packet delay variation between 2 VMs on
-different blades. The reported packet delay variations of the five test runs
-differ from each other. In general, the packet delay of the first two runs look
-similar, for they both stay stable within each run. And the mean packet delay of
-of them are 0.07714 ms and 0.07982 ms respectively. Of the five runs, the third
-has the worst result, because the packet delay reaches 0.08384 ms. The trend of
-therest two runs look the same, for the average packet delay are 0.07808 ms and
-0.07727 ms respectively. The SLA value sets to be 10 ms. The SLA value is used
-as a reference, it has not been defined by OPNFV.
-
-TC012
------
-Lmbench is also used to measure the memory read and write bandwidth, in which
-we use bw_mem to obtain the results. Among the five test runs, the memory
-bandwidth of last three test runs almost keep stable within each run, which is
-11.64, 11.71 and 11.61 GB/s on average. However, the memory read and write
-bandwidth on Sep. 13 has a large range, for it ranges from 6.68 GB/s to 11.73
-GB/s. Here SLA set to be 15 GB/s. The SLA value is used as a reference, it has
-not been defined by OPNFV.
-
-TC014
------
-The Unixbench is used to evaluate the IaaS processing speed with regards to
-score of single cpu running and parallel running. It can be seen from the
-dashboard that the processing test results vary from scores 3208 to 3314, and
-there is only one result one 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 mean packet throughput of the five test runs is between 259.6 kpps and
-318.4 kpps, of which the result of the second run is the highest. The RTT
-results of all the test runs keep flat at approx. 20 ms. It is obvious that the
-PPS results are not as consistent as the RTT results.
-
-The No. flows of the five test runs are 240 k on average and the PPS results
-look a little waved since the largest packet throughput is 398.9 kpps and the
-minimum throughput is 250.6 kpps respectively.
-
-There are no errors of packets received in the five runs, but there are still
-lost packets in all the test runs. The RTT values obtained by ping of the five
-runs have the similar average vaue, that is between 17 ms and 22 ms, of which
-the worest RTT is 53 ms on Sep. 14th.
-
-CPU load is measured by mpstat, and CPU load of the four test runs seem a
-little similar, since the minimum value and the peak of CPU load is between 0
-percent and 10 percent respectively. And the best result is obtained on Sep.
-13rd, with an CPU load of 10 percent.
-
-TC069
------
-With the block size changing from 1 kb to 512 kb, the memory write bandwidth
-tends to become larger first and then smaller within every run test, which
-rangs from 21.6 GB/s to 26.8 GB/s and then to 18.4 GB/s on average. Since the
-test id is one, it is that only the INT memory write bandwidth is tested. On
-the whole, when the block size is 8 kb and 16 kb, the memory write bandwidth
-look similar with a minimal BW of 23.0 GB/s and peak value of 28.6 GB/s. And
-then with the block size becoming larger, the memory write bandwidth tends to
-decrease. SLA sets to be 7 GB/s. The SLA value is used as a a reference, it has
-not been defined by OPNFV.
-
-TC070
------
-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 network latency is measured by ping, and the results of the five test runs
-look similar with each other, and within these test runs, the maximum RTT can
-reach 53 ms and the average RTT is usually approx. 18 ms. The network latency
-tested on Sep. 14 shows that it has a peak latency of 53 ms. But on the whole,
-the average RTTs of the five runs keep flat and the network latency is
-relatively short.
-
-Memory utilization is measured by free, which can display amount of free and
-used memory in the system. The largest amount of used memory is 272 MiB on Sep
-14. In general, the mean used memory of the five test runs have the similar
-trend and the minimum memory used size is approx. 150 MiB, and the average
-used memory size is about 250 MiB. On the other hand, for the mean free memory,
-the five test runs have the similar trend, whose mean free memory change from
-218 MiB to 342 MiB, with an average value of approx. 38 MiB.
-
-Packet throughput and packet loss can be measured by pktgen, which is a tool
-in the network for generating traffic loads for network experiments. The mean
-packet throughput of the five test runs seem quite different, ranging from
-285.29 kpps to 297.76 kpps. The average number of flows in these tests is
-240000, and each run has a minimum number of flows of 2 and a maximum number
-of flows of 1.001 Mil. At the same time, the corresponding packet throughput
-differ between 250.6k and 398.9k with an average packet throughput between
-277.2 K and 318.4 K. In summary, the PPS results seem consistent. Within each
-test run of the five runs, when number of flows becomes larger, the packet
-throughput seems not larger at the same time.
-
-TC071
------
-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 network latency is measured by ping, and the results of the five test runs
-look similar with each other. Within each test run, the maximum RTT is only 49
-ms and the average RTT is usually approx. 20 ms. On the whole, the average
-RTTs of the five runs keep stable and the network latency is relatively short.
-
-Cache utilization is measured by cachestat, which can display size of cache and
-buffer in the system. Cache utilization statistics are collected during UDP
-flows sent between the VMs using pktgen as packet generator tool.The largest
-cache size is 215 MiB in the four runs, and the smallest cache size is 95 MiB.
-On the whole, the average cache size of the five runs change a little and is
-about 200 MiB, except the one on Sep. 14th, the mean cache size is very small,
-which keeps 102 MiB. Meanwhile, the tread of the buffer size keep flat, since
-they have a minimum value of 7 MiB and a maximum value of 8 MiB, with an
-average value of about 7.8 MiB.
-
-Packet throughput can be measured by pktgen, which is a tool in the network for
-generating traffic loads for network experiments. The mean packet throughput of
-the four test runs seem quite different, ranging from 285.29 kpps to 297.76
-kpps. The average number of flows in these tests is 239.7k, and each run has a
-minimum number of flows of 2 and a maximum number of flows of 1.001 Mil. At the
-same time, the corresponding packet throughput differ between 227.3k and 398.9k
-with an average packet throughput between 277.2k and 318.4k. Within each test
-run of the five runs, when number of flows becomes larger, the packet
-throughput seems not larger in the meantime.

-TC072
------
-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
- between 0 ms and 49 ms with an average leatency of less than 22 ms. The PPS
-results are not as consistent as the RTT results, for the mean packet
-throughput of the five runs differ from 250.6 kpps to 398.9 kpps.
-
-Network utilization is measured by sar, that is system activity reporter, which
-can display the average statistics for the time since the system was started.
-Network utilization statistics are collected during UDP flows sent between the
-VMs using pktgen as packet generator tool. The largest total number of packets
-transmitted per second look similar for four test runs, whose values change a
-lot from 10 pps to 399 kpps, except the one on Sep. 14th, whose total number
-of transmitted per second keep stable, that is 10 pps. Similarly, the total
-number of packets received per second look the same for four runs, except the
-one on Sep. 14th, whose value is only 10 pps.
-
-In some test runs when running with less than approx. 90000 flows the PPS
-throughput is normally flatter compared to when running with more flows, after
-which the PPS throughput decreases. 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 250000 flows
-compared to other test runs where the PPS result is less with only 2 flows.
-
-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 differs a lot per test run.
