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 POD2_ or Ericsson POD2_ between September 16 and 20 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 0.32 ms and 1.42 ms. -Only one test run on Sep. 20 has reached greatest RTT spike of 4.66 ms. -Meanwhile, the smallest network latency is 0.16 ms, which is obtained on Sep. -17th. To sum up, the curve of network latency has very small wave, which is -less than 5 ms. SLA sets 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 734 -MB/s. The IO read bandwidth of the first three runs looks similar, with an -average of less than 100 KB/s, except one on Sep. 20, whose maximum storage -throughput can reach 734 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 -1.8k per second and 3.27k per second, and meanwhile, the minimum result is -only 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 1.085 ns and 1.218 -ns on average. The variations within each test run are quite small. For -Ericsson pod2, the average of memory latency is approx. 1.217 ms. While for LF -pod2, the average value is about 1.085 ms. It can be seen that the performance -of LF is better than Ericsson's. The SLA sets to be 30 ns. 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. The four test runs all have a narrow range -of change with the average memory and write BW of 18.5 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 3209k to 3843k, 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 three test runs is between 439 kpps and -582 kpps, and the test run on Sep. 17th has the lowest average value of 371 -kpps. The RTT results of all the test runs keep flat at approx. 10 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 680 kpps and the -minimum throughput is 319 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 trend of RTT with the average value of approx. 12 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 ten percent respectively. And the best result is obtained on Sep. -17th, with an CPU load of ten 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 average memory write -bandwidth tends to become larger first and then smaller within every run test -for the two pods, which rangs from 25.1 GB/s to 29.4 GB/s and then to 19.2 GB/s -on average. Since the test id is one, it is that only the INT memory write -bandwidth is tested. On the whole, 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 27 ms and the average RTT is usually approx. 12 ms. The network latency -tested on Sep. 27th has a peak latency of 27 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 269 MiB for the -four runs. In general, the four test runs have very large memory utilization, -which can reach 251 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 231 MiB to 248 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 -371 kpps to 582 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 319 kpps and 680 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 24 -ms and the average RTT is usually approx. 12 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 213 MiB, and the smallest cache size is 99 MiB, which is same for -the four runs. On the whole, the average cache size of the four runs look the -same and is between 184 MiB and 205 MiB. Meanwhile, the tread of the buffer -size keep stable, since they have a minimum value of 7 MiB and a maximum value of -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 differ from 371 kpps to 582 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 319 kpps to 680 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 24 ms with an average leatency of less than 13 ms. The PPS -results are not as consistent as the RTT results, for the mean packet -throughput of the four runs differ from 370 kpps to 582 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 the four test runs, whose values change a -lot from 10 pps to 697 kpps. However, the total number of packets received per -second of three runs look similar, which have a large wide range of 2 pps to -1.497 Mpps, while the results on Sep. 18th and 20th have very small maximum -number of packets received per second of 817 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 Ericsson POD2_ and LF POD2_ with: -Fuel 9.0 -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. To be decided on in next release of OPNFV. |
