+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 LF POD1_ between September 14 and 17 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 0.49 ms and 0.60 ms.
+Only one test run has reached greatest RTT spike of 0.93 ms. Meanwhile, the
+smallest network latency is 0.33 ms, which is obtained on Sep. 14th.
+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 416
+MB/s. The IO read bandwidth of all four runs looks similar, with an average
+between 128 and 131 MB/s. One of the runs has a minimum BW of 497 KB/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
+IO read times per second of the four test runs have an average value at 1k per
+second, and meanwhile, the minimum result is only 45 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 1.0859 ns and
+1.0869 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 14th, the memory read latency of which is ranging
+from 1.091 ns to 1.086 ns. However.
+The SLA sets to be 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. On the first two test runs the reported packet delay variation varies between
+0.0037 and 0.0740 ms, with an average delay variation between 0.0096 ms and 0.0321.
+On the second date the delay variation varies between 0.0063 and 0.0096 ms, with
+an average delay variation of 0.0124 - 0.0141 ms.
+
+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 trend of
+three memory bandwidth almost look similar, which all have a narrow range, and
+the average result is 19.88 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 3754k to 3831k, 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 between 307.3 kpps and
+447.1 kpps, of which the result of the third run is the highest. The RTT
+results of all the test runs keep flat at approx. 15 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 418.1 kpps and the
+minimum throughput is 326.5 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 approx. 15 ms.
+
+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 nine percent respectively. And the best result is obtained on Sep.
+1, with an CPU load of nine percent. But on the whole, the CPU load is very
+poor, since the average value is quite small.
+
+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 28.2 GB/s to 29.5 GB/s and then to 29.2 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 2 kb or 16 kb, the memory write bandwidth
+look similar with a minimal BW of 25.8 GB/s and peak value of 28.3 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 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 four test runs
+look similar with each other, and within these test runs, the maximum RTT can
+reach 39 ms and the average RTT is usually approx. 15 ms. The network latency
+tested on Sep. 1 and Sep. 8 have a peak latency of 39 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 267 MiB for the
+four runs. In general, the four test runs have very large memory utilization,
+which can reach 257 MiB on average. On the other hand, for the mean free memory,
+the four test runs have the similar trend with that of the mean used memory.
+In general, the mean free memory change from 233 MiB to 241 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 four test runs seem quite different, ranging from
+305.3 kpps to 447.1 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 average packet
+throughput is between 354.4 kpps and 381.8 kpps. In summary, 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 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 four test runs
+look similar with each other. Within each test run, the maximum RTT is only 42
+ms and the average RTT is usually approx. 15 ms. On the whole, the average
+RTTs of the four runs keep stable and the network latency is relatively small.
+
+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 212 MiB, which is same for the four runs, and the smallest cache
+size is 75 MiB. On the whole, the average cache size of the four runs look the
+same and is between 197 MiB and 211 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 7.9 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 differ from 354.4 kpps to 381.8 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 305.3 kpps to 447.1 kpps. 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 42 ms with an average leatency of less than 15 ms. The PPS
+results are not as consistent as the RTT results, for the mean packet
+throughput of the four runs differ from 354.4 kpps to 381.8 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 for three test runs, whose values change a
+lot from 10 pps to 501 kpps. While results of the rest test run seem the same
+and keep stable with the average number of packets transmitted per second of 10
+pps. However, the total number of packets received per second of the four runs
+look similar, which have a large wide range of 2 pps to 815 kpps.
+
+In some test runs when running with less than approx. 251000 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 251000 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.

+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 25 and 29 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 0.5 and 0.6 ms.
+A few runs start with a 1 - 1.5 ms RTT spike (This could be because of normal ARP
+handling). One test run has a greater RTT spike of 1.9 ms, which is the same
+one with the 0.7 ms average. The other runs have no similar spike at all.
+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. 170 and 200 MB/s. Within each test run the results
+vary, with a minimum 2 MB/s and maximum 838 MB/s on the totality. Most runs
+have a minimum BW of 3 MB/s (two runs at 2 MB/s). The maximum BW varies more in
+absolute numbers between the dates, between 617 and 838 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. 1.2 ns. The variations within each test run are similar, between
+1.215 and 1.219 ns. One exception is February 16, where the average is 1.222
+and varies between 1.22 and 1.28 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. On the first date the reported packet delay variation varies between
+0.0025 and 0.011 ms, with an average delay variation of 0.0067 ms.
+On the second date the delay variation varies between 0.002 and 0.006 ms, with
+an average delay variation of 0.004 ms.
+
+TC012
+-----
+Between test dates, the average measurements for memory bandwidth vary between
+17.4 and 17.9 GB/s. Within each test run the results vary more, with a minimal
+BW of 16.4 GB/s and maximum of 18.2 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 3080 and 3240,
+one result each date. The average score on the total is 3150.
+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
+15.5 and 25.4 GB/s. Within each test run the results vary more, with a minimal
+BW of 9.7 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.

+Detailed test results

+Fuel 9.0
+OpenStack Mitaka

+
+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.

+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 183.65
+MB/s. The IO read bandwidth of the three runs looks similar, with an average
+between 62.9 and 64.3 MB/s, except one on Sep. 1, for its maximum storage
+throughput is only 159.1 MB/s. One of the runs has a minimum BW of 685 KB/s and
+other has a maximum BW of 183.6 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
+IO read times per second of the four test runs have an average value between
+1.41k per second and 1.64k per second, and meanwhile, the minimum result is
+only 55 times per second.

+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 1.152 ns and 1.179
+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 8, the memory read latency of which is ranging
+from 1.120 ns to 1.221 ns. However, the results on September 7 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.

+Iperf3 is a tool for evaluating the packet delay variation between 2 VMs on
+different blades. The reported packet delay variations of the four 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 them are 0.0087 ms and 0.0127 ms respectively. Of the four runs, the fourth
+has the worst result, because the packet delay reaches 0.0187 ms. The SLA value
+sets to be 10 ms. The SLA value is used as a reference, it has not been defined
+by OPNFV.

+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 trend of
+three memory bandwidth almost look similar, which all have a narrow range, and
+the average result is 11.78 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.

+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 3260k to 3328k, and

+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 between 307.3 kpps and
+447.1 kpps, of which the result of the third run is the highest. The RTT
+results of all the test runs keep flat at approx. 15 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 418.1 kpps and the
+minimum throughput is 326.5 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 approx. 15 ms.
+
+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 nine percent respectively. And the best result is obtained on Sep.
+1, with an CPU load of nine percent. But on the whole, the CPU load is very
+poor, since the average value is quite small.

+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 21.9 GB/s to 25.9 GB/s and then to 17.8 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 2 kb or 16 kb, the memory write bandwidth
+look similar with a minimal BW of 24.8 GB/s and peak value of 27.8 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 reference, it has
+not been defined by OPNFV.

+
+The network latency is measured by ping, and the results of the four test runs
+look similar with each other, and within these test runs, the maximum RTT can
+reach 39 ms and the average RTT is usually approx. 15 ms. The network latency
+tested on Sep. 1 and Sep. 8 have a peak latency of 39 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 267 MiB for the
+four runs. In general, the four test runs have very large memory utilization,
+which can reach 257 MiB on average. On the other hand, for the mean free memory,
+the four test runs have the similar trend with that of the mean used memory.
+In general, the mean free memory change from 233 MiB to 241 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 four test runs seem quite different, ranging from
+305.3 kpps to 447.1 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 average packet
+throughput is between 354.4 kpps and 381.8 kpps. In summary, 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 at the same time.

+
+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 212 MiB, which is same for the four runs, and the smallest cache
+size is 75 MiB. On the whole, the average cache size of the four runs look the
+same and is between 197 MiB and 211 MiB. Meanwhile, the tread of the buffer
+size keep flat, since they have a minimum value of 7 MiB and a maximum value of

+
+The RTT results are similar throughout the different test dates and runs

+
+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 three test runs, whose values change a
+lot from 10 pps to 501 kpps. While results of the rest test run seem the same
+and keep stable with the average number of packets transmitted per second of 10
+pps. However, the total number of packets received per second of the four runs
+look similar, which have a large wide range of 2 pps to 815 kpps.
+
+In some test runs when running with less than approx. 251000 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 251000 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.
