|test case id | OPNFV_YARDSTICK_TC007_Virtual Traffic Classifier Data Plane |
| | Throughput Benchmarking Test in Presence of Noisy |
| | neighbours |
| | |
+--------------+--------------------------------------------------------------+
|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 in the |
| | presence of noisy neighbours. |
| | |
+--------------+--------------------------------------------------------------+
|configuration | file: opnfv_yardstick_tc007.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 |
| | |
| | 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 |
| | |
| | num_of_neighbours: Number of noisy neighbours (VMs) to be |
| | instantiated during the experiment. |
| | Allowed values: range (1, 10) |
| | |
| | amount_of_ram: RAM to be used by each neighbor. |
| | Allowed values: ['250M', '1G', '2G', '3G', '4G', '5G', |
| | '6G', '7G', '8G', '9G', '10G'] |
| | Deault value: 256M |
| | |
| | number_of_cores: Number of noisy neighbours (VMs) to be |
| | instantiated during the experiment. |
| | Allowed values: range (1, 10) |
| | Default value: 1 |
| | |
| | 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 | DPDKpktgen_ |
| | |
| | ETSI-NFV-TST001 |
| | |
| | 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 noisy neighbours are deployed as required by the user. |
| | |
+--------------+--------------------------------------------------------------+
|step 2 | The vTC is deployed, according to the configuration required |
| | by the user |
| | |
+--------------+--------------------------------------------------------------+
|step 3 | The vTC is correctly deployed and configured as necessary. |
| | The initialization script has been correctly executed and |
| | the vTC is ready to receive and process the traffic. |
| | |
+--------------+--------------------------------------------------------------+
|step 4 | Test case is executed with the parameters specified by the |
| | user: |
| | - vTC flavor |
| | - vNIC type |
| | - packet size |
| | The traffic is sent to the vTC using the maximum available |
| | traffic rate |
| | |
+--------------+--------------------------------------------------------------+
|step 5 | The vTC instance forwards all the packets back to the |
| | packet generator for 60 seconds, as specified by RFC 2544. |
| | |
| | Steps 4 and 5 are executed different times with different |
| | with different traffic rates, in order to find the maximum |
| | supported traffic rate, accoring 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. |
| | |
+--------------+--------------------------------------------------------------+
