7 Yardstick Test Case Description: NSB PROXi VPE
8 **********************************************
10 +-----------------------------------------------------------------------------+
11 |NSB PROX test for NFVI characterization |
13 +--------------+--------------------------------------------------------------+
14 |test case id | tc_prox_{context}_vpe-{port_num} |
16 | | * context = baremetal or heat_context; |
19 +--------------+--------------------------------------------------------------+
20 |metric | * Network Throughput; |
21 | | * TG Packets Out; |
22 | | * TG Packets In; |
23 | | * VNF Packets Out; |
24 | | * VNF Packets In; |
25 | | * Dropped packets; |
27 +--------------+--------------------------------------------------------------+
28 |test purpose | The PROX VPE test handles packet processing, routing, QinQ |
29 | | encapsulation, flows, ACL rules, adds/removes MPLS tagging |
30 | | and performs QoS before forwarding packet to another port. |
31 | | The reverse applies to forwarded packets in the other |
34 | | The VPE test cases are implemented to run in baremetal |
35 | | and heat context an require 4 port topology to run the |
36 | | default configuration. |
38 +--------------+--------------------------------------------------------------+
39 |configuration | The VPE test cases are listed below: |
41 | | * tc_prox_baremetal_vpe-4.yaml |
42 | | * tc_prox_heat_context_vpe-4.yaml |
44 | | Test duration is set as 300sec for each test. |
45 | | The minimum packet size for VPE test is 68 bytes. This is |
46 | | set in the traffic profile and can be configured to use |
47 | | higher packet sizes. |
49 +--------------+--------------------------------------------------------------+
51 | | PROX is a DPDK application that can simulate VNF workloads |
52 | | and can generate traffic and used for NFVI characterization |
54 +--------------+--------------------------------------------------------------+
55 |applicability | The PROX VPE test cases can be configured with |
59 | | * test durations; |
60 | | * tolerated loss; |
62 | | Default values exist. |
64 +--------------+--------------------------------------------------------------+
65 |pre-test | For Openstack test case image (yardstick-samplevnfs) needs |
66 |conditions | to be installed into Glance with Prox and Dpdk included in |
69 | | For Baremetal tests cases Prox and Dpdk must be installed in |
70 | | the hosts where the test is executed. The pod.yaml file must |
71 | | have the necessary system and NIC information |
73 +--------------+--------------------------------------------------------------+
74 |test sequence | description and expected result |
76 +--------------+--------------------------------------------------------------+
77 |step 1 | For Baremetal test: The TG and VNF are started on the hosts |
78 | | based on the pod file. |
80 | | For Heat test: Two host VMs are booted, as Traffic generator |
81 | | and VNF(VPE workload) based on the test flavor. |
83 +--------------+--------------------------------------------------------------+
84 |step 2 | Yardstick is connected with the TG and VNF by using ssh. |
85 | | The test will resolve the topology and instantiate the VNF |
86 | | and TG and collect the KPI's/metrics. |
88 +--------------+--------------------------------------------------------------+
89 |step 3 | The TG will send packets to the VNF. If the number of |
90 | | dropped packets is more than the tolerated loss the line |
91 | | rate or throughput is halved. This is done until the dropped |
92 | | packets are within an acceptable tolerated loss. |
94 | | The KPI is the number of packets per second for 68 bytes |
95 | | packet size with an accepted minimal packet loss for the |
96 | | default configuration. |
98 +--------------+--------------------------------------------------------------+
99 |step 4 | In Baremetal test: The test quits the application and unbind |
100 | | the dpdk ports. |
102 | | In Heat test: Two host VMs are deleted on test completion. |
104 +--------------+--------------------------------------------------------------+
105 |test verdict | The test case will achieve a Throughput with an accepted |
106 | | minimal tolerated packet loss. |
