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. |
