+Yardstick Test Case Description TC021
+*************************************
++-----------------------------------------------------------------------------+
+|Network Performance |
++==============+==============================================================+
+|test case id | OPNFV_YARDSTICK_TC0021_Virtual Traffic Classifier |
+| | Instantiation Test in Presence of Noisy Neighbours |
+| | |
++--------------+--------------------------------------------------------------+
+|metric | Failure |
+| | |
++--------------+--------------------------------------------------------------+
+|test purpose | To verify that a newly instantiated vTC is 'alive' and |
+| | functional and its instantiation is correctly supported by |
+| | the infrastructure in the presence of noisy neighbours. |
+| | |
++--------------+--------------------------------------------------------------+
+|configuration | file: opnfv_yardstick_tc021.yaml |
+| | |
+| | 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 |
+| | |
+| | 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 | DPDK Pktgen: 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. |
+| | Installation and configuration of smcroute is required |
+| | before to run the test case. |
+| | (For further instructions please refer to the ApexLake |
+| | documentation). |
+| | - 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 provided |
+| | 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 selected parameters: |
+| | - vTC flavor |
+| | - vNIC type |
+| | A constant rate traffic is sent to the vTC for 10 seconds. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 5 | The vTC instance tags all the packets and sends them back to |
+| | the packet generator for 10 seconds. |
+| | |
+| | The framework checks if the packet generator receives back |
+| | all the packets with the correct tag from the vTC. |
+| | |
++--------------+--------------------------------------------------------------+
+|test verdict | The vTC is deemed to be successfully instantiated if all |
+| | packets are sent back with the right tag as requested, |
+| | else it is deemed DoA (Dead on arrival) |
+| | |
