As use of the Internet continues to spread rapidly, Traffic Engineering (TE) is needed to optimize IP network resource utilization. In particular, load balancing with TE can prevent traffic concentration on a single path between ingress and egress routers. As real-time applications, such as VoIP and streaming services, continue to grow in popularity, network control that takes latency and jitter into account is increasingly essential. We propose a dynamic load balancing method with priority control which considers these factors, and have constructed an MPLS (Multi-Protocol Label Switching) network with TE capability in the JGN (Japan Gigabit Network). We evaluated the method's effectiveness in the MPLS network from the viewpoint of control stability.
