Arrangement for distributing and dispatching traffic in a network, especially H.323 generated traffic
First Claim
1. An internal gatekeeper for distributing and dispatching traffic in a network, wherein:
- the traffic is based on ITU-T-recommendation H.323;
the internal gatekeeper is arranged in a specific domain and is adapted to put an endpoint of the specific domain in contact with an external real gatekeeper placed outside the specific domain, the external real gatekeeper supporting a full H.323 message set;
the internal gatekeeper supports a subset of the H.323 message set used by any endpoint when registering to an external real gatekeeper, the subset including GRQ (Gatekeeper Request), GCF (Gatekeeper Confirm), GRJ (Gatekeeper Reject), IRR (Information Request Response), IRQ (Information Request), RAI (Resource Availability Indication), RAC (Resource Availability Confirm), RRQ (Registration Request), RCF (Registration Confirm), and RRJ (Registration Reject);
the internal gatekeeper is arranged to maintain a list or table of valid real gatekeepers; and
the external real gatekeeper is arranged to register an internal gatekeeper during start-up.

Abstract
The present invention relates to an arrangement for distributing and dispatching traffic in a network, especially H.323 generated traffic, which arrangement comprises one or more gatekeepers, here designated as so-called external or real gatekeepers, and for the purpose of utilizing such real gatekeepers in a far more efficient and cost saving manner, and also for avoiding reconfiguration of endpoints depending on which gatekeepers with which they want to communicate, the present invention suggests a solution characterized by the introduction of one or more internal gatekeepers, here also designated as so-called internal lightweight gatekeepers, each such internal gatekeeper basically understanding any message used by any endpoint when registering to a real gatekeeper.
