Topology Window
To open the Topology window, click Topology in the Windows Menu. Use this
window to define topology islands for the Gatekeeper.
An island is a cluster of components. Dividing the network into islands enables the
Gatekeeper to direct calls through the most optimal routes, avoiding slow
connections or bottlenecks as much as possible. If you use the island scheme, the
Gatekeeper routes Service calls first to the Service providers, or Gateways that belong
to the same island, and then to other islands. This ensures that the call is directed
over the fastest available channel. The word subnet is used here to help define an
island. The meaning of subnet in this context may be different from actual subnets on
the network. It is possible to define a single host as a subnet by using 255.255.255.255
as a mask. In this way, a subnet is actually an “island portion.”
Figure 8-1 Topology window
The Topology window displays a list of all islands with the following information:
• Island ID
The island identifier. Set the Island ID field in the Topology Island Component
View dialog box.
• Size
The number of components in the island.
