+| | Throughput Benchmarking Test. |
+| | |
++--------------+--------------------------------------------------------------+
+|metric | Throughput |
+| | |
++--------------+--------------------------------------------------------------+
+|test purpose | To measure the throughput supported by the virtual Traffic |
+| | Classifier according to the RFC2544 methodology for a |
+| | user-defined set of vTC deployment configurations. |
+| | |
++--------------+--------------------------------------------------------------+
+|configuration | file: file: opnfv_yardstick_tc006.yaml |
+| | |
+| | packet_size: size of the packets to be used during the |
+| | throughput calculation. |
+| | Allowe values: [64, 128, 256, 512, 1024, 1280, 1518] |
+| | |
+| | vnic_type: type of VNIC to be used. |
+| | Allowed values are: |
+| | - normal: for default OvS port configuration |
+| | - direct: for SR-IOV port configuration |
+| | Default value: None |
+| | |
+| | vtc_flavor: OpenStack flavor to be used for the vTC |
+| | Default available values are: m1.small, m1.medium, |
+| | and m1.large, but the user can create his/her own |
+| | flavor and give it as input |
+| | Default value: None |
+| | |
+| | vlan_sender: vlan tag of the network on which the vTC will |
+| | receive traffic (VLAN Network 1). |
+| | Allowed values: range (1, 4096) |
+| | |
+| | vlan_receiver: vlan tag of the network on which the vTC |
+| | will send traffic back to the packet generator |
+| | (VLAN Network 2). |
+| | Allowed values: range (1, 4096) |
+| | |
+| | default_net_name: neutron name of the defaul network that |
+| | is used for access to the internet from the vTC |
+| | (vNIC 1). |
+| | |
+| | default_subnet_name: subnet name for vNIC1 |
+| | (information available through Neutron). |
+| | |
+| | vlan_net_1_name: Neutron Name for VLAN Network 1 |
+| | (information available through Neutron). |
+| | |
+| | vlan_subnet_1_name: Subnet Neutron name for VLAN Network 1 |
+| | (information available through Neutron). |
+| | |
+| | vlan_net_2_name: Neutron Name for VLAN Network 2 |
+| | (information available through Neutron). |
+| | |
+| | vlan_subnet_2_name: Subnet Neutron name for VLAN Network 2 |
+| | (information available through Neutron). |
+| | |

+|test tool | DPDK pktgen |
+| | |
+| | DPDK Pktgen is not part of a Linux distribution, |
+| | hence it needs to be installed by the user. |
+| | |
++--------------+--------------------------------------------------------------+
+|references | DPDK Pktgen: DPDKpktgen_ |
+| | |
+| | ETSI-NFV-TST001 |
+| | |
+| | RFC 2544: rfc2544_ |
+| | |
++--------------+--------------------------------------------------------------+
+|applicability | Test can be configured with different flavors, vNIC type |
+| | and packet sizes. Default values exist as specified above. |
+| | The vNIC type and flavor MUST be specified by the user. |
+| | |
++--------------+--------------------------------------------------------------+
+|pre-test | The vTC has been successfully instantiated and configured. |
+| | The user has correctly assigned the values to the deployment |
+| | configuration parameters. |
+| | |
+| | - Multicast traffic MUST be enabled on the network. |
+| | The Data network switches need to be configured in |
+| | order to manage multicast traffic. |
+| | - In the case of SR-IOV vNICs use, SR-IOV compatible NICs |
+| | must be used on the compute node. |
+| | - Yarsdtick needs to be installed on a host connected to the |
+| | data network and the host must have 2 DPDK-compatible |
+| | NICs. Proper configuration of DPDK and DPDK pktgen is |
+| | required before to run the test case. |
+| | (For further instructions please refer to the ApexLake |
+| | documentation). |
+| | |
++--------------+--------------------------------------------------------------+
+|test sequence | Description and expected results |
+| | |
++--------------+--------------------------------------------------------------+
+|step 1 | The vTC is deployed, according to the user-defined |
+| | configuration |
+| | |
++--------------+--------------------------------------------------------------+
+|step 2 | The vTC is correctly deployed and configured as necessary |
+| | The initialization script has been correctly executed and |
+| | vTC is ready to receive and process the traffic. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 3 | Test case is executed with the selected parameters: |
+| | - vTC flavor |
+| | - vNIC type |
+| | - packet size |
+| | The traffic is sent to the vTC using the maximum available |
+| | traffic rate for 60 seconds. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 4 | The vTC instance forwards all the packets back to the packet |
+| | generator for 60 seconds, as specified by RFC 2544. |
+| | |
+| | Steps 3 and 4 are executed different times, with different |
+| | rates in order to find the maximum supported traffic rate |
+| | according to the current definition of throughput in RFC |
+| | 2544. |
+| | |
++--------------+--------------------------------------------------------------+
+|test verdict | The result of the test is a number between 0 and 100 which |
+| | represents the throughput in terms of percentage of the |
+| | available pktgen NIC bandwidth. |
+| | |
