Bandwidth Control Examples
Example Without a Firewall
An example deployment is shown opposite. In this example,
there are three geographically separate ofces: Enterprise,
Branch and Home. All endpoints in the Enterprise ofce register
with the VCS Control, as do those in the Branch and Home
ofces.
Each of the three ofces is represented as a separate subzone
on the VCS, with bandwidth congured according to local policy.
The enterprise’s leased line connection to the Internet, and the
DSL connections to the remote ofces are modeled as separate
pipes.
There are no rewalls involved in this scenario, so we can
congure direct links between each of the ofces. Each link is
then assigned two pipes, representing the Internet connections
of the ofces at each end of the link.
In this scenario, a call placed between the Home Ofce and
Branch Ofce will consume bandwidth from the Home and
Branch subzones and on the Home and Branch pipes. The
Enterprise’s bandwidth budget will be unaffected by the call.
