GLOSSARY
A
AAA
AAA refers to Authentication, Authorization, and Accounting, which is a security architecture for
distributed systems that determines the access given to users for specific services and the amount of
resources they have used.
aggregation
A user-defined collection of network elements. For example, an aggregation can contain devices,
links, VPNs, and other aggregations.
alarm
Sequence of event notifications that share the same source, cause, or fault. For example, if a single
port goes up and then down, these two events in a related sequence may result in a single alarm. An
alarm is stateful and is opened when a fault is first detected. Event notifications may be added to the
alarm, and it is archived when it is fixed.
association
A relationship between the following types of network elements: a logical (protocol-oriented)
network element and a physical network element; a logical network element and another logical
network element; or an existing association and anything else. An example for a VPN would be an
association between the physical IP interface and Virtual Routing and Forwarding (VRF) table,
which is the associated routing table. An association is not considered a topological link.
B
BFD
Bidirectional Forwarding Detection (BFD) is used to detect communication failures between two
elements, or endpoints, that are connected by a link, such as a virtual circuit, tunnel, or LSP.
BNG
Broadband Network Gateway (BNG) provides capabilities that help to improve the service provider's
ability to manage the subscriber's services, and simplify overall network operations.
business element
Construction or organization of certain network elements and their properties into a logical entity, to
provide the ability to track them in a way that makes sense from a business perspective. A virtual
private network (VPN) is a business element, which represents a set of interconnected sites that form
a single network over a public network. Prime Network organizes the business elements in a way that
creates a containment hierarchy that reflects the VPN structure.
business tag
A string that is meaningful to the business, and that can be used to label a component of a network
element for use in Prime Network screens and reports. There are three types of business tags:
subscriber, provider, and label. Business tags are stored in the Prime Network gateway database.
