AWS |
Amazon Web Services (AWS) is a secure cloud services platform, offering compute, database storage, content delivery and other
functionalities.
|
ESC
|
Elastic Services Controller (ESC) is a Virtual Network Function Manager (VNFM), performing lifecycle management of Virtual
Network Functions.
|
ETSI
|
European Telecommunications Standards Institute (ETSI) is an independent standardization organization that has been instrumental
in developing standards for information and communications technologies (ICT) within Europe.
|
ETSI Deployment Flavour
|
A deployment flavour definition contains information about affinity relationships, scaling, min/max VDU instances, and other
policies and constraints to be applied to the VNF instance. The deployment flavour defined in the VNF Descriptor (VNFD) must
be selected by passing the flavour_id attribute in the InstantiateVNFRequest payload during the instantiate VNF LCM operation.
|
HA
|
ESC High
Availability (HA) is a solution for preventing single points of ESC failure and
achieving minimum ESC downtime.
|
KPI
|
Key
Performance Indicator (KPI) measures performance management. KPIs specify what,
how and when parameters are measured. KPI incorporates information about
source, definitions, measures, calculations for specific parameters.
|
NFV
|
Network
Function Virtualization (NFV) is the principle of separating network functions
from the hardware they run on by using virtual hardware abstraction.
|
NFVO
|
NFV
Orchestrator (NFVO) is a functional block that manages the Network Service (NS)
lifecycle and coordinates the management of NS lifecycle, VNF lifecycle
(supported by the VNFM) and NFVI resources (supported by the VIM) to ensure an
optimized allocation of the necessary resources and connectivity.
|
NSO
|
Cisco
Network Services Orchestrator (NSO) is an orchestrator for service activation
which supports pure physical networks, hybrid networks (physical and virtual)
and NFV use cases.
|
OpenStack Compute Flavor
|
Flavors define the compute, memory, and storage capacity of nova computing instances. A flavor is an available hardware configuration
for a server. It defines the size of a virtual server that can be launched.
|
Service
|
A service consists of a single or multiple VNFs.
|
VDU |
The Virtualisation Deployment Unit (VDU) is a construct that can be used in an information model, supporting the description
of the deployment and operational behaviour of a subset of a VNF, or the entire VNF if it was not componentized in subsets.
|
VIM
|
The
Virtualized Infrastructure Manager (VIM) adds a management layer for the data
center hardware. Its northbound APIs are consumed by other layers to manage the
physical and virtual resources for instantiation, termination, scale in and out
procedures, and fault & performance alarms.
|
VM
|
A Virtual
Machine (VM) is an operating system OS or an application installed on a
software, which imitates a dedicated hardware. The end user has the same
experience on a virtual machine as they would have on dedicated hardware.
|
VNF
|
A Virtual
Network Function (VNF) consists of a single or a group of VMs with different
software and processes that can be deployed on a Network Function
Virtualization (NFV) Infrastructure.
|
VNFM
|
Virtual
Network Function Manager (VNFM) manages the life cycle of a VNF.
|
vMS
|
Cisco vMS
is a Network Functions Virtualization (NFV) orchestration platform that enables
fast deployment of cloud-based networking services.
