There have been research initiatives in centralized control recently, which advocate that the control of an autonomous system (AS) should be performed in a centralized fashion. In this paper, we propose an approach to perform traffic engineering and routing in networks with centralized control, named LP-redirect. LP-redirect is based on an efficient formulation of linear programming (LP) that reduces the number of variables and constraints. As LP is not fast enough for runtime routing, LP-redirect uses a fast scheme to recompute routing paths when a network topology changes. The performance evaluation of LP-redirect shows that it is more efficient in both traffic engineering and computation than an approach using optimized link weights. In addition, LP-redirect is suitable for runtime traffic engineering and routing. © 2008 Springer-Verlag Berlin Heidelberg.
