Bandwidth control examples
An example deployment is shown opposite. In this example,
there are three geographically separate offices: Head, Branch
and Home. All endpoints in the Head Office register with the VCS
Control, as do those in the Branch and Home offices.
Each of the three offices 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 (Pipe
B and Pipe C). The Head Office's bandwidth budget will be
unaffected by the call.
