The Bandwidth Management feature in the 3300 ICP tracks and manages bandwidth consumption by the VoIP media stream. This feature allows you to do the following for the voice data packets at predetermined bottleneck points in the network:
Measure and report consumed and available bandwidth
Establish maintenance alarms when bandwidth consumption exceeds configured threshold levels.
Provide Call Admission Control, that is, the rejection of new calls through a specific bottleneck point when consumed bandwidth exceeds maximum configured levels.
Bandwidth management may be based on a need to:
Limit the bandwidth used by voice to allow sufficient bandwidth for data based applications (such as banking transactions) that voice traffic must not degrade
Define the limit at which the voice quality may suffer.
To configure Bandwidth Management, you need to look at your network and see where the bottlenecks are. Once you have this view, you model the network into groupings or zones; in essence, you put an overlay onto your network that defines zones for ICPs, devices, sets, consoles, and so forth that need to be virtually co-located in the same zones to allow bandwidth to be measured.
Note: Bandwidth Management is not supported in MLPP A feature that supports emergency communications for the military as part of the Defense Switched Network (DSN). MLPP enables authorized users to specify a precedence level when they make a call, and to preempt calls that have a lower precedence level. installations. Using it may block calls that MLLP would otherwise allow to pass.
