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 POD5_ between September 12 and 15 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 1.50 and 1.68 ms. +Only one test run has reached greatest RTT spike of 2.92 ms, which has +the smallest RTT of 1.06 ms. The other three runs have no similar spike at all, +the minimum and average RTTs of which are approx. 1.50 ms and 1.68 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 177.5 +MB/s. The IO read bandwidth of the four runs looks similar on different four +days, with an average between 46.7 and 62.5 MB/s. One of the runs has a minimum +BW of 680 KM/s and other has a maximum BW of 177.5 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 +test runs all have an approx. 1.55 K/s for IO reading with an minimum value of +less than 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 1.134 ns and 1.227 +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 15, the memory read latency of which is ranging +from 1.116 ns to 1.393 ns. However, the results on September 12 change very +little, which mainly keep flat and range from 1.124 ns to 1.55 ns. 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 pocket delay variation between 2 VMs on +different blades. The reported pocket delay variations of the four test runs +differ from each other. The results on September 13 within the date look +similar and the values are between 0.0213 and 0.0225 ms, which is 0.0217 ms on +average. However, on the third day, the packet delay variation has a large +wide change within the date, which ranges from 0.008 ms to 0.0225 ms and has +the minimum value. On Sep. 12, the packet delay is quite long, for the value is +between 0.0236 and 0.0287 ms and it also has the maximum packet delay of 0.0287 +ms. The packet delay of the last test run is 0.0151 ms on average. 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 memory +bandwidth of three test runs almost keep stable within each run, which is +11.65, 11.57 and 11.64 GB/s on average. However, the memory read and write +bandwidth on Sep. 14 has a large range, for it ranges from 11.36 GB/s to 16.68 +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 3222 to 3585, 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 124.8, 160.1, 113.8 and +137.3 kpps, of which the result of the second is the highest. The RTT results +of all the test runs keep flat at approx. 37 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 243.1 kpps and the +minimum throughput is 37.6 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 between 32 ms and 41 ms, of which +the worest RTT is 155 ms on Sep. 14th. + +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 9 percent respectively. And the best result is obtained on Sep. +15th, with an CPU load of nine percent. + +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 22.4 GB/s to 26.5 GB/s and then to 18.6 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 8 kb and 16 kb, the memory write bandwidth +look similar with a minimal BW of 22.5 GB/s and peak value of 28.7 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 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 three test runs look +similar with each other, and Within these test runs, the maximum RTT can reach +95 ms and the average RTT is usually approx. 36 ms. The network latency tested +on Sep. 14 shows that it has a peak latency of 155 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 270 MiB on Sep +13, which also has the smallest minimum memory utilization. Besides, the rest +three test runs have the similar used memory with an average memory usage of +264 MiB. On the other hand, the free memory of the four runs have the same +smallest minimum value, that is about 223 MiB, and the maximum free memory of +three runs have the similar result, that is 226 MiB, except that on Sep. 13th, +whose maximum free memory is 273 MiB. On the whole, all the test runs have +similar average free memory. + +Network 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 +network throughput of the four test runs seem quite different, ranging from +119.85 kpps to 128.02 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 packet throughput +differ between 38k and 243k with an average packet throughput of approx. 134k. +On the whole, 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 in the meantime. + +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 can reach +79 ms and the average RTT is usually approx. 35 ms. On the whole, the average +RTTs of the four runs keep flat. + +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 214 MiB in the four runs, and the smallest cache size is 100 MiB. +On the whole, the average cache size of the four runs is approx. 210 MiB. +Meanwhile, the tread of the buffer size looks similar with each other. On the +other hand, the mean buffer size of the four runs keep flat, since they have a +minimum value of approx. 7 MiB and a maximum value of 8 MiB, with an average +value of about 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 seem quite different, ranging from 113.8 kpps to 124.8 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 47.6k and 243.1k with +an average packet throughput between 113.8k and 160.1k. 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 79 ms with an average leatency of approx. 35 ms. The PPS +results are not as consistent as the RTT results, for the mean packet +throughput of the four runs differ from 113.8 kpps to 124.8 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 on the first three runs with a minimum +number of 10 pps and a maximum number of 97 kpps, except the one on Sep. 15th, +in which the number of packets transmitted per second is 10 pps. Meanwhile, the +largest total number of packets received per second differs from each other, +in which the smallest number of packets received per second is 1 pps and the +largest of that is 276 kpps. + +In some test runs when running with less than approx. 90000 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 1000000 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 POD5_ 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.
