-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 Intel POD5_ between September 12 and 15 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 2.92 ms, which has
-the smallest RTT of 1.06 ms. The other three runs have no similar spike at all,
-the minimum and average RTTs of which are approx. 1.50 ms and 1.68 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 177.5
-MB/s. The IO read bandwidth of the four runs looks similar on different four
-days, with an average between 46.7 and 62.5 MB/s. One of the runs has a minimum
-BW of 680 KM/s and other has a maximum BW of 177.5 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 four runs look similar with each other. The
-test runs all have an approx. 1.55 K/s for IO reading with an minimum value of
-less than 60 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 four runs is between 1.134 ns and 1.227
-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 15, the memory read latency of which is ranging
-from 1.116 ns to 1.393 ns. However, the results on September 12 change very
-little, which mainly keep flat and range from 1.124 ns to 1.55 ns. 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 pocket delay variation between 2 VMs on
-different blades. The reported pocket delay variations of the four test runs
-differ from each other. The results on September 13 within the date look
-similar and the values are between 0.0213 and 0.0225 ms, which is 0.0217 ms on
-average. However, on the third day, the packet delay variation has a large
-wide change within the date, which ranges from 0.008 ms to 0.0225 ms and has
-the minimum value. On Sep. 12, the packet delay is quite long, for the value is
-between 0.0236 and 0.0287 ms and it also has the maximum packet delay of 0.0287
-ms. The packet delay of the last test run is 0.0151 ms on average. 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 four test runs, the memory
-bandwidth of three test runs almost keep stable within each run, which is
-11.65, 11.57 and 11.64 GB/s on average. However, the memory read and write
-bandwidth on Sep. 14 has a large range, for it ranges from 11.36 GB/s to 16.68
-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 3222 to 3585, 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 four test runs is 124.8, 160.1, 113.8 and
-137.3 kpps, of which the result of the second is the highest. The RTT results
-of all the test runs keep flat at approx. 37 ms. It is obvious that the PPS
-results are not as consistent as the RTT results.
-
-The No. flows of the four test runs are 240 k on average and the PPS results
-look a little waved since the largest packet throughput is 243.1 kpps and the
-minimum throughput is 37.6 kpps respectively.
-
-There are no errors of packets received in the four runs, but there are still
-lost packets in all the test runs. The RTT values obtained by ping of the four
-runs have the similar average vaue, that is between 32 ms and 41 ms, of which
-the worest RTT is 155 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 9 percent respectively. And the best result is obtained on Sep.
-15th, with an CPU load of nine 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 22.4 GB/s to 26.5 GB/s and then to 18.6 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 22.5 GB/s and peak value of 28.7 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 three test runs look
-similar with each other, and Within these test runs, the maximum RTT can reach
-95 ms and the average RTT is usually approx. 36 ms. The network latency tested
-on Sep. 14 shows that it has a peak latency of 155 ms. But on the whole, the
-average RTTs of the four runs keep flat.
-
-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 270 MiB on Sep
-13, which also has the smallest minimum memory utilization. Besides, the rest
-three test runs have the similar used memory with an average memory usage of
-264 MiB. On the other hand, the free memory of the four runs have the same
-smallest minimum value, that is about 223 MiB, and the maximum free memory of
-three runs have the similar result, that is 226 MiB, except that on Sep. 13th,
-whose maximum free memory is 273 MiB. On the whole, all the test runs have
-similar average free memory.
-
-Network 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
-network throughput of the four test runs seem quite different, ranging from
-119.85 kpps to 128.02 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 38k and 243k with an average packet throughput of approx. 134k.
-On the whole, the PPS results seem consistent. Within each test run of the four
-runs, when number of flows becomes larger, the packet throughput seems not
-larger in the meantime.
-
-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 four test runs
-look similar with each other. Within each test run, the maximum RTT can reach
-79 ms and the average RTT is usually approx. 35 ms. On the whole, the average
-RTTs of the four runs keep flat.
-
-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 214 MiB in the four runs, and the smallest cache size is 100 MiB.
-On the whole, the average cache size of the four runs is approx. 210 MiB.
-Meanwhile, the tread of the buffer size looks similar with each other. On the
-other hand, the mean buffer size of the four runs keep flat, since they have a
-minimum value of approx. 7 MiB and a maximum value of 8 MiB, with an average
-value of about 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 113.8 kpps to 124.8 kpps.
-The average number of flows in these tests is 240k, 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 47.6k and 243.1k with
-an average packet throughput between 113.8k and 160.1k. Within each test run of
-the four 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 79 ms with an average leatency of approx. 35 ms. The PPS
-results are not as consistent as the RTT results, for the mean packet
-throughput of the four runs differ from 113.8 kpps to 124.8 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 on the first three runs with a minimum
-number of 10 pps and a maximum number of 97 kpps, except the one on Sep. 15th,
-in which the number of packets transmitted per second is 10 pps. Meanwhile, the
-largest total number of packets received per second differs from each other,
-in which the smallest number of packets received per second is 1 pps and the
-largest of that is 276 kpps.
-
-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 1000000 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.
