A group-to-group CAC policy is required if a mesh network topology is present. This policy is used to represent the properties of a dedicated bandwidth-limited link between two CAC groups—for example, between two branch offices that have a dedicated link to one another.
A Group-To-Group CAC Policy contains the same information as a CAC Policy. However:
The administrator must specify additional information so that it is assigned to two CAC Groups rather than one.
It does not have secondary link capacities.
The figure below provides examples of group-to-group CAC Policy usage. In these examples, Group-To-Group CAC Policies are present for:
The voice traffic between branches 1 and 2. A separate policy is applicable to the fax and video traffic between the branches.Figure 1. Call Admission Control — Group-To-Group CAC Policies
