Network Performance Benchmarking¶
Like compute or storage QPI, network QPI gives users an overall score for system network performance. For now it focuses on L2 virtual switch performance on NFVI. Current testcase are from RFC2544 standart and implemntation is based on Spirent Testcenter Virtual.
For now, network QPI runs against on the baremetal/virtual scenario deployed by the OPNFV installer APEX.
Getting started¶
Notice: All descriptions are based on containers.
Requirements¶
- Git must be installed.
- Docker and docker-compose must be installed.
- Spirent Testcenter Virtual image must be uploaded to the target cloud and the
associated flavor must be created before test.
- Spirent License Server and Spirent LabServer must be set up and keep them ip
reachable from target cloud external network before test.
Git Clone QTIP Repo¶
git clone https://git.opnfv.org/qtip
Running QTIP container and Nettest Containers¶
With Docker Compose, we can use a YAML file to configure application’s services and use a single command to create and start all the services.
There is a YAML file ./qtip/tests/ci/network/docker-compose.yaml from QTIP repos.
It can help you to create and start the network QPI service.
Before running docker-compose, you must specify these three variables:
DOCKER_TAG, which specified the Docker tag(ie: latest)
SSH_CREDENTIALS, a directory which includes an SSH key pair will be mounted into QTIP container. QTIP use this SSH key pair to connect to remote hosts.
ENV_FILE, which includes the environment variables required by QTIP and Storperf containers
A example of ENV_FILE:
INSTALLER_TYPE=apex INSTALLER_IP=192.168.122.247 TEST_SUITE=network NODE_NAME=zte-virtual5 SCENARIO=generic TESTAPI_URL= OPNFV_RELEASE=euphrates # The below environment variables are Openstack Credentials. OS_USERNAME=admin OS_USER_DOMAIN_NAME=Default OS_PROJECT_DOMAIN_NAME=Default OS_BAREMETAL_API_VERSION=1.29 NOVA_VERSION=1.1 OS_PROJECT_NAME=admin OS_PASSWORD=ZjmZJmkCvVXf9ry9daxgwmz3s OS_NO_CACHE=True COMPUTE_API_VERSION=1.1 no_proxy=,192.168.37.10,192.0.2.5 OS_CLOUDNAME=overcloud OS_AUTH_URL=http://192.168.37.10:5000/v3 IRONIC_API_VERSION=1.29 OS_IDENTITY_API_VERSION=3 OS_AUTH_TYPE=password # The below environment variables are extra info with Spirent. SPT_LICENSE_SERVER_IP=192.168.37.251 SPT_LAB_SERVER_IP=192.168.37.122 SPT_STCV_IMAGE_NAME=stcv-4.79 SPT_STCV_FLAVOR_NAME=m1.tiny
Then, you use the following commands to start network QPI service.
docker-compose -f docker-compose.yaml pull
docker-compose -f docker-compose.yaml up -d
Execution¶
You can run network QPI with docker exec:
docker exec <qtip container> bash -x /home/opnfv/repos/qtip/qtip/scripts/quickstart.sh
QTIP generates results in the $PWD/results/ directory are listed down under the
timestamp name.
