4.2Bandwidth Control Examples

One possible configuration for the deployment in Figure 4 is shown in Figure 8. Each of the offices is represented as a separate subzone, with bandwidth configured according to local policy. The enterprise’s leased line connection to the Internet, and the DSL connections to the remote offices, are modelled as separate pipes.

Figure 8: Bandwidth control example

There are no firewalls involved in the scenario shown in figure 4, so we can configure links between each of the offices. Each link is then assigned two pipes, representing the Internet connections of the offices at each end of the link. A call placed between the Home Office and Branch Office will consume bandwidth in the home and branch subzones and on the home and branch pipe. The enterprise’s bandwidth budget will be unaffected by the call.

If we now modify our deployment to include firewalls between the offices, we can use the firewall traversal capability of the TANDBERG Gatekeeper and Border Controller to maintain connectivity.

In Figure 9, the endpoints in the enterprise register with the Gatekeeper, whilst those in the branch and home office register with the Border Controller.

Figure 10 shows how the Border Controller could be configured for the deployment in Figure 9. The introduction of the firewalls means that there is no longer any direct connectivity between the Branch and Home offices. All traffic must be routed through the Border Controller. This is shown by the absence of a link between the Home and Branch subzones.

The Traversal Zone in Figure 10 represents the Enterprise Gatekeeper. The Border Controller will consume bandwidth from the Traversal Zone for all calls placed to endpoints managed by the Enterprise Gatekeeper. In this example we have assumed that there is no bottleneck on the link between the Border Controller and the Enterprise network, so have not placed a pipe on this link. If you want to limit the amount of traffic flowing through your firewall, you could provision a pipe on this link.
