As part of call admission control (CAC), a bandwidth policy is used to define bandwidth limitations for certain modalities. In Microsoft Lync Server 2013, only audio and video modalities can be assigned bandwidth limitations. You can set overall bandwidth limitations and session limitations. You can use the Lync Server Control Panel to create, modify, or delete a container profile for these policies. Each bandwidth policy profile can be associated with one or more network sites. Use the following procedures to create or modify a bandwidth policy profile. To delete a bandwidth policy profile, see Deleting Network Bandwidth Policy Profiles

To create a new bandwidth policy profile

  1. From a user account that is a member of the RTCUniversalServerAdmins group (or has equivalent user rights), or is assigned to the CsAdministrator role, log on to any computer in your internal deployment.

  2. Open a browser window, and then enter the Admin URL to open the Lync Server Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server Administrative Tools.

  3. In the left navigation bar, click Network Configuration and then click Bandwidth Policy.

  4. On the Bandwidth Policy page, click New.

  5. In New Bandwidth Policy Profile, type a name in the Name field. This name must be unique among all bandwidth policy profiles.

  6. In the Audio limit field, type a numeric value. This value is the maximum amount of bandwidth to allocate for all audio connections, expressed in kbps.

  7. Enter a numeric value in the Audio session limit field. This value is the maximum amount of bandwidth to allocate for an individual audio connection, expressed in kbps. This value must be 40 or higher.

  8. Enter a numeric value in the Video limit field. This value is the maximum amount of bandwidth to allocate for all video connections, expressed in kbps.

  9. Enter a numeric value in the Video session limit field. This value is the maximum amount of bandwidth to allocate for an individual video connection, expressed in kbps. This value must be 100 or higher.

  10. (Optional) Type a value in the Description field to provide more information about this bandwidth policy profile that cannot be expressed by the name alone.

  11. Click Commit.

    Note:
    Creating a new bandwidth policy profile does not automatically enforce bandwidth restrictions. You must first associate the policy profile with a site. For details about how to associate a policy profile with a site, see Creating or Modifying Network Sites.

To modify a bandwidth policy profile

    Note:
    When you modify the bandwidth policy profile, it will immediately update the bandwidth limitations of all network sites associated with this bandwidth policy profile.
