NMS
Network Management System: The system responsible for managing a portion of
a network. The NMS talks to network management agents, which reside in the
managed nodes, via a network management protocol. The NMS is the entity that
implements functions at the Network Management Layer. It may also include
Element Management Layer functions. A Network Management System may
manage one or more other Network Management Systems.
NML
Network Management Layer: An abstraction of the functions provided by systems
which manage network elements on a collective basis, so as to monitor and control
the network end-to-end.
NMS
Network Management System: An entity that implements functions at the Network
Management Layer. It may also include Element Management Layer functions. A
Network Management System may manage one or more other Network
Management Systems.
NMS Environment
A set of NMS which cooperate to manage one or more subnetworks.
NNI
Network Node Interface: An interface between ATM switches defined as the
interface between two network nodes.
Nodal Attribute
A nodal state parameter that is considered individually to determine whether a
given node is acceptable and/or desirable for carrying a given connection.
Nodal Constraint
A restriction on the use of nodes for path selection for a specific connection.
Nodal Metric
A nodal parameter that requires the values of the parameter for all nodes along a
given path to be combined to determine whether the path is acceptable and/or
desirable for carrying a given connection.
Nodal State Parameter
Information that captures an aspect or property of a node.
