Choosing a Gatekeeper Platform
The exact gatekeeper platform required for an H.323 network depends on how
large the H.323 network is and how many other functions (if any) the router will
be performing.The more endpoints, gateways, and calls in an H.323 network, the
larger the router platform required for the gatekeeper.A router dedicated for
gatekeeper tasks will have considerably more resources available than a router
performing several other functions in addition to gatekeeper.
Ideally, the gatekeeper should connect to the network using 100 Mbps
Ethernet, though for small networks, a 10 Mbps Ethernet connection will suffice.
When selecting router memory, remember the rule:There is no such thing as
too much memory. However, it should be noted that gatekeeper functionality
does not require an enormous amount of memory. For example, to support the
configuration for 10,000 zones, only an additional 4MB of memory is required.
More memory would be necessary to monitor the calls, but this gives you an idea
that the gatekeeper does not require tremendous memory.
