Design Considerations
When designing your H.323 network, you should try to think of what a complete,
fully implemented H.323 design would look like. Attempt to implement
your (probably smaller) H.323 network with this vision in mind. Networks
inevitably continuously grow. It is much easier to start with a large-scale design
even in a small network and scale it to a large network than it is to begin with a
small-scale design and scale it to a large network.
Although the gatekeeper can be located anywhere in the network, since it is a
central point of control, the optimal location is near the center of the network or
near the center of the H.323 network.The gatekeeper should be connected to
the network via a 10 Mbps or—ideally—a 100 Mbps Ethernet switched link.
