Abstract
In this paper, we focus on a practical experiment concerning IP traffic engineering over Multi-Protocol Label Switching (MPLS), especially which features feedback control capabilities. We present control-theoretic analysis of the experimental results based on acquired knowledge of actual network behavior. Because stable automated control capabilities are key issues in IP traffic engineering, we model an IP traffic control system based on the resulting analysis. In addition, comparison between simulated network behavior and actual one shows this model to have a high degree of stability, with a high potential for application to real networks.
