Research on Agent-Based Call Routing Architecture for Video Communication

Drawbacks such as agglutination between call process and call routing, heavy routing overhead, poor scalability and control complexity, exist in current large-scale multimedia communication. To overcome these disadvantages, we proposed a hybrid hierarchical call routing architecture based on agent. In this layered architecture, instructed by the goal of condensation and flat, and improving transmission efficiency, used intelligent Agent. Our call routing architecture not only has smaller call delay than conventional hierarchical one, but could balance load of softswitch entities. Extensive simulation results show that the proposed hybrid architecture based on agent reduces location complexity in large-scale video communication switching and improves multi-domain access efficiency. It expands video communication scale and achieves high performance for multimedia video service at less cost.
