About Bandwidth Control - Cisco TelePresence Administrator's Manual

About bandwidth control

The 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 using
used:
within each subzone
n
between a subzone and another subzone
n
between a subzone and a zone
n
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.
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 xCommand CheckBandwidth.
For specific information about how bandwidth is managed across peers in a cluster, see
across peers.
Example network deployment
The following diagram shows a typical network deployment:
a broadband LAN between the Enterprise and the internet, where high bandwidth calls are acceptable
n
a pipe to the internet (Pipe A) with restricted bandwidth
n
two satellite offices, Branch and Home, each with their own internet connections and restricted pipes
n
In this example each pool of endpoints has been assigned to a different subzone, so that suitable limitations
can be applied to the bandwidth used within and between each subzone based on the amount of bandwidth
they have available via their internet connections.
