This MIB module defines textual conventions used by the MIB
modules defining objects describing flow monitoring.
Alarm Action - a method used by the device to signal changes in
an alarm condition.
Alarm Aggregation - a technique used to efficiently monitor the
same standing condition for a flow set.
Alarm Condition - a standing condition for which the device
signals changes in state.
Alarm Group - a flow set for which the device monitors a
configured standing condition, raising an alarm when a
configured number of flows in the flow set assert the
Alarm Severity - the relative disposition of an alarm condition
when raised by the device. For example, a provider may
regard a flow stop alarm as having a higher severity than a
flow's loss fraction exceeding a configured threshold.
Flow Monitor - a hardware or software entity that classifies
traffic flows, collects flow data, and periodically
computes flow metrics.
Flow Metric - a measurement that reflects the quality of a
Flow Point - represents the ingress or egress of a traffic flow.
Flow Set - a group of traffic flows.
Measurement Interval - the length of time over which a flow
monitor collects data related to a traffic flow, after which
the flow monitor computes flow metrics using the collected
Standing Condition - represents a lasting error, fault, or
warning resulting from the application of a set of criteria
to the state of an entity, such as a flow monitor or traffic
flow. For example, a flow monitor may assert a standing
condition if the number of traffic flows that expire in a
meansurement interval exceeds a configured threshold.
Traffic Flow - a unidirectional stream of packets conforming to
a classifier. For example, packets having a particular
source IP address, destination IP address, protocol type,
source port number, and destination port number.
