2.18. Glossary
- API
- Application Programming Interface
- Barometer
- OPNFV NFVi Service Assurance project. Barometer upstreams changes to
collectd, OpenStack, etc to improve features related to NFVi monitoring
and service assurance.
More info on: https://opnfv-barometer.readthedocs.io/en/latest/
- collectd
- collectd is a system statistics collection daemon.
More info on: https://collectd.org/
- context
- A context describes the environment in which a yardstick testcase will
be run. It can refer to a pre-provisioned environment, or an environment
that will be set up using OpenStack or Kubernetes.
- Docker
- Docker provisions and manages containers. Yardstick and many other OPNFV
projects are deployed in containers. Docker is required to launch the
containerized versions of these projects.
- DPDK
- Data Plane Development Kit
- DPI
- Deep Packet Inspection
- DSCP
- Differentiated Services Code Point
- flavor
- A specification of virtual resources used by OpenStack in the creation
of a VM instance.
- Grafana
- A visualization tool, used in Yardstick to retrieve test data from
InfluxDB and display it. Grafana works by defining dashboards, which are
combinations of visualization panes (e.g. line charts and gauges) and
forms that assist the user in formulating SQL-like queries for InfluxDB.

- IGMP
- Internet Group Management Protocol
- InfluxDB
- One of the Dispatchers supported by Yardstick, it allows test results to
be reported to a time-series database.
More info on: https://www.influxdata.com/
- IOPS
- Input/Output Operations Per Second
A performance measurement used to benchmark storage devices.
- KPI
- Key Performance Indicator
- Kubernetes
- k8s
Kubernetes is an open-source container-orchestration system for automating
deployment, scaling and management of containerized applications.
It is one of the contexts supported in Yardstick.
- MPLS
- Multiprotocol Label Switching
- NFV
- Network Function Virtualization
NFV is an initiative to take network services which were traditionally run
on proprietary, dedicated hardware, and virtualize them to run on general
purpose hardware.
- NFVI
- Network Function Virtualization Infrastructure
The servers, routers, switches, etc on which the NFV system runs.
- NIC
- Network Interface Controller
- NSB
- Network Services Benchmarking. A subset of Yardstick features concerned
with NFVI and VNF characterization.
- OpenStack
- OpenStack is a cloud operating system that controls pools of compute,
storage, and networking resources. OpenStack is an open source project
licensed under the Apache License 2.0.
- PBFS
- Packet Based per Flow State
- PROX
- Packet pROcessing eXecution engine
- QoS
- Quality of Service
The ability to guarantee certain network or storage requirements to
satisfy a Service Level Agreement (SLA) between an application provider
and end users.
Typically includes performance requirements like networking bandwidth,
latency, jitter correction, and reliability as well as storage
performance in Input/Output Operations Per Second (IOPS), throttling
agreements, and performance expectations at peak load
- runner
- The part of a Yardstick testcase that determines how the test will be run
(e.g. for x iterations, y seconds or until state z is reached). The runner
also determines when the metrics are collected/reported.
- SampleVNF
- OPNFV project providing a repository of reference VNFs.
More info on: https://opnfv-samplevnf.readthedocs.io/en/latest/
- scenario
- The part of a Yardstick testcase that describes each test step.
- SLA
- Service Level Agreement
An SLA is an agreement between a service provider and a customer to
provide a certain level of service/performance.
- SR-IOV
- Single Root IO Virtualization
A specification that, when implemented by a physical PCIe
device, enables it to appear as multiple separate PCIe devices. This
enables multiple virtualized guests to share direct access to the
physical device.
- SUT
- System Under Test
- testcase
- A task in Yardstick; the yaml file that is read by Yardstick to
determine how to run a test.
- ToS
- Type of Service
- VLAN
- Virtual LAN (Local Area Network)
- VM
- Virtual Machine
An operating system instance that runs on top of a hypervisor.
Multiple VMs can run at the same time on the same physical
host.
- VNF
- Virtual Network Function
- VNFC
- Virtual Network Function Component
