An example deployment is shown opposite.
Each of the three offices (Enterprise, Home and Branch) is
represented as a separate subzone on the VCS, 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 modeled as
separate pipes.
There are no firewalls involved in this scenario, so we can
configure direct 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.
In this scenario, a call placed between the Home Office and
Branch Office 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.
