# Simplifying Bandwidth Management Within a Network

You may want to isolate the bandwidth management of certain regions of the network from the bandwidth management of other regions to simplify measurement and alarm reporting.

If you isolate regions, the bandwidth measurement and alarm reporting is local to the region, and is not affected by other isolated regions. This approach allows you to separate complex networks into smaller, more manageable sections for bandwidth management.

The term "Perimeter" is used to define the edges of these regions. For Perimeter zone applications, the Network Zone Topology form (includes the Zone Tree Assignment and the Zone Access Point Assignment) must only be shared within each region's cluster and not across the network. You can then use the same zone numbers, behind the perimeter zone, as other clusters.

The following graphic show an example of how you can configure regions that only have bandwidth management only within their own cluster. The bandwidth management does not extend beyond the region to other regions.

Bandwidth Management Regions

In the example shown below, the administrator of the North American region is only interested in the bandwidth information for the local cluster zone information. The "Perimeter Zone" (Zone 4) defines the outside edges of the North America region and isolates it from the United Kingdom region and Europe region.

The IT Administrator has assigned the following bandwidth limits for the voice media streams through the ZAPs as follows:

ZAP Label | Bandwidth Limit
Paris-Ottawa | 1000 kbit/s
Toronto-Ottawa | 500 kbit/s
Phoenix-Ottawa | 500 kbit/s
London-Ottawa | 1000 kbit/s

Network Zone Configuration

The following network zone configuration shown is simplified below for such a configuration.

## Tree Model Representation

In the North America cluster, Zone 4 is programmed as the Perimeter Zone. You must ensure that the zone of the ICP on the other edge of the Perimeter does not conflict with any other zones within its cluster. In this example, Zone 5 and Zone 6 must not be used within the North American region.

To create the perimeter zone for the North American cluster, you would program the bandwidth management forms as follows:

Network Elements |  | Zone Tree Assignment
Name | Zone | Zone | Parent Zone | Perimeter
Ottawa (Local) | 4 | 2 | 4 | No
London | 5 | 3 | 4 | No
Paris | 6 | 5 | 4 | Yes
Phoenix | 3 | 6 | 4 | Yes
Toronto | 2 |  |  |

Zone Access Point Assignment (Summary)
Zone | Zone Access Point ID | Zone Access Point Label | Bandwidth Limit | Network Element
2 | 1 | Toronto-Ottawa | 500 | Ottawa
3 | 1 | Phoenix-Ottawa | 500 | Ottawa
5 | 1 | London-Ottawa | 1000 | Ottawa
6 | 1 | Paris-Ottawa | 1000 | Ottawa
