Zones and Neighbors
This section describes how to configure zones and neighbors on the Expressway (Configuration > Zones).
About your Video Communications Network
The most basic implementation of a video communications network is a single Expressway connected to the internet
with one or more endpoints registered to it. However, depending on the size and complexity of your enterprise the
Expressway may be part of a network of endpoints, other Expressways and other network infrastructure devices, with
one or more firewalls between it and the internet. In such situations you may want to apply restrictions to the amount
of bandwidth used by and between different parts of your network.

This section provides 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 Expressway to best suit your own
infrastructure.

Example network diagram
The diagram below shows the different components of an Expressway (i.e. subzones and zones) and how they
interrelate. Using an Expressway-C 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 Expressways and to the internet via
different types of zones.

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