CISCO-MDI-METRICS-MIB
AI MIB Summary
The CISCO-MDI-METRICS-MIB enables Cisco network devices to monitor Media Delivery Index (MDI) parameters, specifically Media Loss Rate (MLR) and Delay Factor (DF), to quantify packet loss and jitter for time-sensitive traffic flows. These metrics facilitate the assessment of network quality for streaming media, VoIP, and MPEG video applications by simulating virtual buffer behavior to predict playback performance.
This MIB module defines objects that describe the Media Delivery Index (MDI). The MDI [RFC4445] measurement describes the quality indicator of a network intended to delivery applications such as streaming media, MPEG video, VoIP, or other information sensitive to arrival time and packet loss.
GLOSSARY ============
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 Loss Rate - the number of lost or out-of-order packets over a measurement interval.
Media Rate - the effective bit rate of the media content carried by a traffic flow.
MLR - Media Loss Rate.
MR - Media Rate.
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 application can render their content.
