|         This MIB module defines textual conventions used by the MIB
modules defining objects describing flow monitoring.
        
GLOSSARY
============
        
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
    standing standing.
        
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
    traffic flow.
        
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
    data.
        
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.
