This is | +| | set in the BNG traffic profile and can be configured to use | +| | a higher packet size for the test. | +| | | ++--------------+--------------------------------------------------------------+ +|test tool | PROX | +| | PROX is a DPDK application that can simulate VNF workloads | +| | and can generate traffic and used for NFVI characterization | +| | | ++--------------+--------------------------------------------------------------+ +|applicability | The PROX BNG test cases can be configured with different: | +| | | +| | * packet sizes; | +| | * test durations; | +| | * tolerated loss; | +| | | +| | Default values exist. | +| | | ++--------------+--------------------------------------------------------------+ +|pre-test | For Openstack test case image (yardstick-samplevnfs) needs | +|conditions | to be installed into Glance with Prox and Dpdk included in | +| | it. The test need multi-queue enabled in Glance image. | +| | | +| | For Baremetal tests cases Prox and Dpdk must be installed in | +| | the hosts where the test is executed. The pod.yaml file must | +| | have the necessary system and NIC information | +| | | ++--------------+--------------------------------------------------------------+ +|test sequence | description and expected result | +| | | ++--------------+--------------------------------------------------------------+ +|step 1 | For Baremetal test: The TG 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(BNG workload) based on the test flavor. | +| | | ++--------------+--------------------------------------------------------------+ +|step 2 | Yardstick is connected with the TG and VNF by using ssh. | +| | The test will resolve the topology and instantiate the VNF | +| | and TG and collect the KPI's/metrics. | +| | | ++--------------+--------------------------------------------------------------+ +|step 3 | The TG will send packets to the VNF. 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 78 bytes | +| | 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: Two host VMs are deleted on test completion. | +| | | ++--------------+--------------------------------------------------------------+ +|test verdict | The test case will achieve a Throughput with an accepted | +| | minimal tolerated packet loss. | ++--------------+--------------------------------------------------------------+ + -- cgit 1.2.3-korg
