Bandwidth Control Examples
TANDBERG VIDEO COMMUNICATIONS SERVER ADMINISTRATOR GUIDE
Example Without a Firewall
An example deployment is shown opposite. In this example, there are three geographically separate offices: Enterprise, Branch and Home. All endpoints in the Enterprise 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. The Enterprise’s bandwidth budget will be unaffected by the call.
