+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.
