|Throughput per NFVI node test |
| |
+--------------+--------------------------------------------------------------+
|test case id | OPNFV_YARDSTICK_TC073_Network latency and throughput between |
| | nodes |
| | |
+--------------+--------------------------------------------------------------+
|metric | Network latency and throughput |
| | |
+--------------+--------------------------------------------------------------+
|test purpose | To evaluate the IaaS network performance with regards to |
| | flows and throughput, such as if and how different amounts |
| | of packet sizes and flows matter for the throughput between |
| | nodes in one pod. |
| | |
+--------------+--------------------------------------------------------------+
|configuration | file: opnfv_yardstick_tc073.yaml |
| | |
| | Packet size: default 1024 bytes. |
| | |
| | Test length: default 20 seconds. |
| | |
| | The client and server are distributed on different nodes. |
| | |
| | For SLA max_mean_latency is set to 100. |
| | |
+--------------+--------------------------------------------------------------+
|test tool | netperf |
| | Netperf is a software application that provides network |
| | bandwidth testing between two hosts on a network. It |
| | supports Unix domain sockets, TCP, SCTP, DLPI and UDP via |
| | BSD Sockets. Netperf provides a number of predefined tests |
| | e.g. to measure bulk (unidirectional) data transfer or |
| | request response performance. |
| | (netperf is not always part of a Linux distribution, hence |
| | it needs to be installed.) |

+--------------+--------------------------------------------------------------+
|applicability | Test can be configured with different packet sizes and |
| | test duration. Default values exist. |
| | |
| | SLA (optional): max_mean_latency |
| | |
+--------------+--------------------------------------------------------------+
|pre-test | The POD can be reached by external ip and logged on via ssh |
|conditions | |
+--------------+--------------------------------------------------------------+
|test sequence | description and expected result |
| | |
+--------------+--------------------------------------------------------------+
|step 1 | Install netperf tool on each specified node, one is as the |
| | server, and the other as the client. |
| | |
+--------------+--------------------------------------------------------------+
|step 2 | Log on to the client node and use the netperf command to |
| | execute the network performance test |
| | |
+--------------+--------------------------------------------------------------+
|step 3 | The throughput results stored. |
| | |
+--------------+--------------------------------------------------------------+
|test verdict | Fails only if SLA is not passed, or if there is a test case |
| | execution problem. |
| | |
