摘要
An Internet Protocol (IP) telephony system manages Gatekeeper subscriber load by assigning subscriber load among a plurality of Gatekeepers during the Gatekeeper discovery and registration process. A Registration Load Management Unit (RLMU) is primarily responsible for assigning subscriber load to the plurality of Gatekeepers. In one embodiment, the plurality of Gatekeepers are organized without a hierarchy structure and are made up of a plurality of Gatekeeper service nodes and a plurality of Gatekeeper Database nodes. The Gatekeeper service nodes provide the Registration, Admission, Status, Location, Call Set Up and other operating functions of the Gatekeeper while the plurality of Gatekeeper Database nodes store subscriber information. In a second embodiment, the plurality of Gatekeepers are organized in a hierarchy with a Root Gatekeeper at the top of the hierarchy and a plurality of Gatekeepers residing below the Root Gatekeeper in the hierarchy.
