H.323 Gatekeeper
Encyclopedia : H : H3 : H32 : H.323 Gatekeeper
H.323 Gatekeeper utilities are virtual network switches, which translate network addresses and aliases to make connections via the H.323 protocol on a packet-switched network. A gatekeeper can also deny access or limit the number of simultaneous connections to prevent network congestion.
Terminals which provide multimedia content using this protocol in the H.323 "zone" (e.g. Microsoft NetMeeting) are required to register "at the gate". The registration goes into effect, once the terminal provides its address.
Mandatory Gatekeeper Functions
