The Bandwidth Modeling feature helps you determine how well network links will handle the additional traffic from a VoIP implementation. Bandwidth Modeling works in conjunction with the Network Inventory and Utilization assessment, or it can function as a standalone tool to calculate the potential effects of a configuration change in your network. Bandwidth Modeling helps you:
Model the effects of different codecs and call volumes
Model the effects of RTP header compression and silence suppression
Try out multiple VoIP usage scenarios
Perform a Network Inventory and a Utilization assessment before you model bandwidth. For more information, see Section 3.0, Task 1: Performing a Network Inventory and Section 5.0, Task 3: Assessing Network Utilization.
After discovering devices and links and gathering utilization statistics on your network, Vivinet Assessor can use this information for Bandwidth Modeling. You then select the links you want to model from a table of discovered links whose utilization statistics are known. You cannot make these selections while Utilization monitoring is still active.
You use the Model Bandwidth view to model a particular WAN or LAN link.
