Bandwidth management
To manage bandwidth across different segments of the network you must create zones that
define your network boundaries for IP telephony. Configuring bandwidth management zones
allows you to control how much IP call traffic goes across different parts of your data network.
It prevents your IP telephony users from making more IP calls than the network connections are
capable of supporting.
A bandwidth management zone is defined by a range of IP addresses. You can create as many
zones as you have boundaries where you need to control bandwidth use. There are three types
of configurable zones:
•
Home Zone. This is the zone that controls IP call bandwidth on your local Wave Server.
•
Remote Zone. Remote zones control bandwidth usage on sets of IP address at a remote
site, for example a branch office or home office.
•
Default Remote Zone. This zone handles bandwidth management for IP calls from any
IP address that is not defined in one of the other zones. A call from an undefined IP
address is constrained by the properties configured in the default remote zone.
The following diagram illustrates bandwidth management zones:
