+| | VMs |
+| | |
++--------------+--------------------------------------------------------------+
+|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 |
+| | 2 VMs in one pod. |
+| | |
++--------------+--------------------------------------------------------------+
+|configuration | file: opnfv_yardstick_tc083.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. |
