2.18. Glossary
- API
- Application Programming Interface
- 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
- IGMP
- Internet Group Management Protocol
- 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.
- 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
- 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
- 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
- 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
