CISCO-IP-CBR-METRICS-MIB
AI MIB Summary
The CISCO-IP-CBR-METRICS-MIB enables monitoring of IP Constant Bit Rate (CBR) traffic flows on Cisco devices by exposing specific quality-of-service metrics including Delay Factor (DF), Media Rate (MR), and Media Rate Variation (MRV). These objects allow network administrators to quantify flow rate imbalances and packet delivery consistency over defined measurement intervals to assess the performance of real-time media streams.
This MIB module defines objects that describe the a set of metrics used to measure the quality of a IP CBR traffic flow. An IP CBR traffic flow consists of a stream of IP datagrams sent from one application to another with a constant packet rate or bit rate.
GLOSSARY ============
CBR - Constant Bit Rate.
Delay Factor - the maximum observed value of the flow rate imbalance over a measurement interval.
DF - Delay Factor.
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.
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.
Media Rate - the effective bit rate of the media content carried by a traffic flow.
Media Rate Variation - a measure of loss (in bytes):
N RT - sum [Si] i=1 MRV = RT
where R is the nominal media rate, T is the measurement interval, Si is the size of packet[i] received during the measurement interval, and N is the number of media packets received during the measurement interval.
MR - Media Rate.
MRV - Media Rate Variation.
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.
VB - Virtual Buffer.
Virtual Buffer - a virtual buffer is a construct used to simulate a real buffer used by a media application for the purpose of storing media packets until the the application can render their content.
