TANDBERG VIDEO COMMUNICATIONS SERVER ADMINISTRATOR GUIDE

About your Video Communications Network

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 firewalls 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 configure your VCS to best suit your own infrastructure.

Example Network Diagram

The diagram opposite shows the different components of a VCS (i.e. subzones and zones) 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.

All these components are described in more detail in the sections that follow.
