-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.

-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 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.

-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.
-

-Detailed test results
----------------------
-The scenario was run on Ericsson POD2_ and LF POD2_ with:
-Fuel 9.0
-OpenStack Mitaka
-OpenVirtualSwitch 2.5.90
-OpenDayLight Beryllium
-
-Rationale for decisions
------------------------
-Pass
-
-Tests were successfully executed and metrics collected.
-No SLA was verified. To be decided on in next release of OPNFV.
-
-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.

-
-TC002
------
-The round-trip-time (RTT) between 2 VMs on different blades is measured using
-ping. Most test run measurements result on average between 1.01 ms and 1.88 ms.
-Only one test run has reached greatest RTT spike of 1.88 ms. Meanwhile, the

-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.

-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.

-
-Round trip times and packet throughput between VMs can typically be affected by

-
-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.
