Introduction
The most basic implementation of a TANDBERG
video communications network is a single VCS
connected to the internet with one or more
endpoints registered to it. However, depending
on the size and complexity of your enterprise
the VCS may be part of a network of endpoints,
other VCSs and other network infrastructure
devices, with one or more rewalls between it
and the internet. In such situations you may
wish to apply restrictions to the amount of
bandwidth used by and between different parts
of your network.
This section will give you an overview of the
different parts of the video communications
network and the ways in which they can be
connected. This information should allow you
to congure your VCS to best suit your own
infrastructure.
Example Network Diagram
The diagram opposite shows the different
components of a VCS (subzones, zones and
Alternates) and how they interrelate. Using
a VCS Control as the example Local Zone,
it shows that it is made up of a number of
subzones which are all connected by links. The
Local Zone is also connected to external VCSs
and to the internet via different types of zones.
The VCS also has 4 Alternates to provide
resilience.
All these components are described in more
detail in the sections that follow.
