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 POD6_ between September 1 and 8 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 1.01 ms and 1.88 ms. +Only one test run has reached greatest RTT spike of 1.88 ms. Meanwhile, the +smallest network latency is 1.01 ms, which is obtained on Sep. 1st. In general, +the average of network latency of the four test runs are between 1.29 ms and +1.34 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 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 KM/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. + +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 1.152 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. + +TC011 +----- +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. + +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 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. + +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 3260k to 3328k, 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 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. + +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. + +Detailed test results +--------------------- +The scenario was run on Intel POD6_ with: +Joid +OpenStack Mitaka +OpenVirtualSwitch 2.5.90 +OpenDayLight Beryllium + +Rationale for decisions +----------------------- +Pass + +Conclusions and recommendations +------------------------------- +Tests were successfully executed and metrics collected. +No SLA was verified.
