These can be configured | +| | | ++---------------+--------------------------------------------------------------+ +| test tool | The vFW is a DPDK application that performs basic filtering | +| | for malformed packets and dynamic packet filtering of | +| | incoming packets using the connection tracker library. | +| | | ++---------------+--------------------------------------------------------------+ +| applicability | The vFW RFC2544 test cases can be configured with different: | +| | | +| | * packet sizes; | +| | * test duration; | +| | * tolerated loss; | +| | * traffic flows; | +| | * rules; | +| | | +| | Default values exist. | +| | | ++---------------+--------------------------------------------------------------+ +| pre-test | For OpenStack test case image (yardstick-samplevnf) needs | +| conditions | to be installed into Glance with vFW and DPDK included in | +| | it (NSB install). | +| | | +| | For Baremetal tests cases vFW and DPDK must be installed on | +| | the hosts where the test is executed. The pod.yaml file must | +| | have the necessary system and NIC information. | +| | | +| | For standalone (SA) SRIOV/OvS test cases the | +| | yardstick-samplevnf image needs to be installed on hosts and | +| | pod.yaml file must be provided with necessary system, NIC | +| | information. | +| | | ++---------------+--------------------------------------------------------------+ +| test sequence | Description and expected result | +| | | ++---------------+--------------------------------------------------------------+ +| step 1 | For Baremetal test: The TG (except IXIA) and VNF are started | +| | on the hosts based on the pod file. | +| | | +| | For Heat test: Two host VMs are booted, as Traffic generator | +| | and VNF(vFW) based on the test flavor. In case of scale-out | +| | scenario the multiple VNF VMs will be started. | +| | | +| | For Heat external test: vFW VM is booted and TG (except IXIA)| +| | generator is started on the external host based on the pod | +| | file. In case of scale-out scenario the multiple VNF VMs | +| | will be deployed. | +| | | +| | For Heat SRIOV external test: vFW VM is booted with network | +| | interfaces of `direct` type which are mapped to VFs that are | +| | available to OpenStack. TG (except IXIA) is started on the | +| | external host based on the pod file. In case of scale-out | +| | scenario the multiple VNF VMs will be deployed. | +| | | +| | For SRIOV test: VF ports are created on host's PFs specified | +| | in the TC file and VM is booed using those ports and image | +| | provided in the configuration. TG (except IXIA) is started | +| | on other host connected to VNF machine based on the pod | +| | file. The vFW is started in the booted VM. In case of | +| | scale-out scenario the multiple VNF VMs will be created. | +| | | +| | For OvS-DPDK test: OvS DPDK switch is started and bridges | +| | are created with ports specified in the TC file. DPDK vHost | +| | ports are added to corresponding bridge and VM is booed | +| | using those ports and image provided in the configuration. | +| | TG (except IXIA) is started on other host connected to VNF | +| | machine based on the pod file. The vFW is started in the | +| | booted VM. In case of scale-out scenario the multiple VNF | +| | VMs will be deployed. | +| | | ++---------------+--------------------------------------------------------------+ +| step 2 | Yardstick is connected with the TG and VNF by using ssh (in | +| | case of IXIA TG is connected via TCL interface). The test | +| | will resolve the topology and instantiate all VNFs | +| | and TG and collect the KPI's/metrics. | +| | | ++---------------+--------------------------------------------------------------+ +| step 3 | The TG will send packets to the VNFs. If the number of | +| | dropped packets is more than the tolerated loss the line | +| | rate or throughput is halved. This is done until the dropped | +| | packets are within an acceptable tolerated loss. | +| | | +| | The KPI is the number of packets per second for different | +| | packet size with an accepted minimal packet loss for the | +| | default configuration. | +| | | ++---------------+--------------------------------------------------------------+ +| step 4 | In Baremetal test: The test quits the application and unbind | +| | the DPDK ports. | +| | | +| | In Heat test: All VNF VMs and TG are deleted on test | +| | completion. | +| | | +| | In SRIOV test: The deployed VM with vFW is destroyed on the | +| | host and TG (exclude IXIA) is stopped. | +| | | +| | In Heat SRIOV test: The deployed VM with vFW is destroyed, | +| | VFs are released and TG (exclude IXIA) is stopped. | +| | | +| | In OvS test: The deployed VM with vFW is destroyed on the | +| | host and OvS DPDK switch is stopped and ports are unbinded. | +| | The TG (exclude IXIA) is stopped. | +| | | ++---------------+--------------------------------------------------------------+ +| test verdict | The test case will achieve a Throughput with an accepted | +| | minimal tolerated packet loss. | ++---------------+--------------------------------------------------------------+ + |
