Regions within a network are linked through physical WAN connectivity. A network region link creates a link between two regions configured for call admission control and sets the bandwidth limitations on audio and video traffic between these regions.

For more information about working with network region links, see the Communications Server Management Shell documentation for the following cmdlets:

The example topology has a link between the North America and APAC regions, and a link between the EMEA and APAC regions. Each of these region links is constrained by WAN bandwidth, as described in Region Link Bandwidth Information table in the “Example: Gathering the Required Information for Call Admission Control” section of the Planning documentation.

To create network region links

  1. Open Communications Server Management Shell.

  2. Run the New-CsNetworkRegionLink cmdlet to create the region links and apply appropriate bandwidth policy profiles. For example, run:

    Copy Code 
    New-CsNetworkRegionLink -NetworkRegionLinkID NA_EMEA -NetworkRegionID1 NorthAmerica -NetworkRegionID2 EMEA -BWPolicyProfileID 50Mb_Link
    Copy Code 
    New-CsNetworkRegionLink -NetworkRegionLinkID EMEA_APAC -NetworkRegionID1 EMEA -NetworkRegionID2 APAC -BWPolicyProfileID 25Mb_Link
