Load Balancing Improvement Methods in Video Conferencing Based on H.323 Standard

H.323 standard provides a foundation for audio communications, video, and other data through IP-based networks, including the Internet. By following H.323, products and multimedia applications from multiple manufacturers can interoperate with each other, allowing users to communicate with each other without worrying about interoperability. While the H.323 is continuously revised, however, still many important issues need to be further discussed. In particular, bandwidth management, address translation and intelligent routing, which are the main functions of an H.323 gatekeeper. In fact, the call routing methods used in the current version of H.323 is very basic and will cause an imbalance to keep the gatekeeper. This article will propose a method named Multiple-Registration with Single Database (MRSD).It also describes the design principles and discuss the effectiveness of this method is based on the performance of the system is implemented.
