+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.
