The NAM will provide RTP packet loss statistics so that the quality of video streams for video over IP
applications such as IPTV and Video on Demand can be easily and proactively observed. The goal of the
NAM video stream monitoring feature is to enable the proactive analysis of video traffic to help assure a high
rate of packet delivery so users and subscribers get the picture they expect and demand.
The NAM will monitor live RTP streams to detect drops to an accuracy of 10-6. These packet loss events
will be recorded in a log file.
Thresholds can be defined on certain packet loss attributes and the user can be alerted when a threshold is
exceeded using an SNMP trap.
