Bandwidth policies define limitations on bandwidth usage for real-time audio and video modalities. Bandwidth policies are applied to bandwidth policy profiles, which can be applied to multiple network sites for call admission control.

For guidelines about what bandwidth limits you should set in your CAC deployment, see “Planning for Call Admission Control” in the Planning documentation.

For more information about working with bandwidth policies and policy profiles, see the Communications Server Management Shell documentation for the following cmdlets:

The example policies created in the following procedure set limits for overall audio traffic, individual audio sessions, overall video traffic, and individual video sessions. For example, the 5Mb_Link bandwidth policy profile sets the following limits:

To create bandwidth policy profiles

  1. Open Communications Server Management Shell.

  2. For each bandwidth policy profile that you want to create, run the New-CsNetworkBandwidthPolicyProfile cmdlet. For example, run:

    Copy Code
    New-CsNetworkBandwidthPolicyProfile -Identity 5Mb_Link –Desription “BW profile for 5Mb links” -AudioBWLimit 2000 -AudioBWSessionLimit 200 -VideoBWLimit 1400  -VideoBWSessionLimit 700
    Copy Code
    New-CsNetworkBandwidthPolicyProfile -Identity 10Mb_Link –Desription “BW profile for 10Mb links” -AudioBWLimit 4000 -AudioBWSessionLimit 200 -VideoBWLimit 2800 -VideoBWSessionLimit 700
    Copy Code
    New-CsNetworkBandwidthPolicyProfile -Identity 50Mb_Link –Desription “BW profile for 50Mb links” -AudioBWLimit 20000 -AudioBWSessionLimit 200 -VideoBWLimit 14000 -VideoBWSessionLimit 700
    Copy Code
    New-CsNetworkBandwidthPolicyProfile -Identity 25Mb_Link –Desription “BW profile for 25Mb links” -AudioBWLimit 10000 -AudioBWSessionLimit 200 -VideoBWLimit 7000 -VideoBWSessionLimit 700
