Bandwidth Control Overview

The diagram below shows a typical network deployment:

a broadband LAN between the Enterprise and the internet, where high bandwidth calls are acceptable

a pipe to the internet (Pipe A) with restricted bandwidth

two satellite offices, Branch and Home, each with their own internet connections and restricted pipes.

In this example we have created new subzone for each pool of endpoints, so that we can apply suitable limitations to the bandwidth used within and
between each subzone based on the amount of bandwidth they have available via their internet connections.

The TANDBERG VCS allows you to control
the amount of bandwidth used by endpoints
on your network. This is done by grouping
endpoints into subzones, and then applying
limits to the bandwidth that can be used:

within each subzone

between a subzone and another subzone

between a subzone and a zone.

Bandwidth limits may be set on a call-by-call
basis and/or on a total concurrent usage basis.
This flexibility allows you to set appropriate
bandwidth controls on individual components
of your network.
This section describes the different types of
subzones and how to add and configure them,
and explains how to use

Links

and

Pipes

to

apply bandwidth controls between subzones
and zones.

Calls will fail if links are not
configured correctly. You can check
whether a call will succeed, and what

bandwidth will be allocated to it, using the
command
