Study on H.323-based distributed gatekeepers

  • The scalability of H.323-based video conferencing system is closely re lated to the architecture of gatekeeper (GK). A distributed H .323 gatekeeper architecture based on multiple zones was proposed, providing the solution for the deployment of multimedia video conferencing system on the large scale netwo rk. This architecture did not only conquer the drawback of centralized architect ure and hierarchical architecture, but could balance the load between gatekeeper s. Design of GK-level signaling message routing based on alias format was used t o solve the communication problem between endpoints registered in different zone s. In the zone, the centralized architecture was adopted and the main-GK manage d the slave-GKs. Balancing load factor algorithm(BLFA) was presented to balance the load between gatekeepers.
