There have been research initiatives in centralized control recently, which advocatethat the control of an autonomous system (AS) should be performed in acentralized fashion. In this paper, we propose an approach to perform traffic engineeringand routing in networks with centralized control, named LP-redirect.LP-redirect is based on an efficient formulation of linear programming (LP) thatreduces the number of variables and constraints. As LP is not fast enough for runtimerouting, LP-redirect uses a fast scheme to recompute routing paths when anetwork topology changes. The performance evaluation of LP-redirect shows thatit is more efficient in both traffic engineering and computation than an approachusing optimized link weights. In addition, LP-redirect is suitable for runtime trafficengineering and routing.
