Abstract

In this paper we evaluate approaches that allow the re-routing of a set of already established label switched paths (LSPs) in multiprotocol label switching (MPLS) networks when a new LSP demand faces constrained shortest path first failure. Two optimization algorithms are proposed: one is based on an integer linear programming formulation of the problem, while the other one is a heuristic method based on Dijkstra's shortest path first algorithm. We analyze the efficiency of our algorithms in a dynamic network environment. The simulation experiments show that our method significantly increases the total network throughput. We also investigate the limitations of the applicability of proposed methods considering their running time. © 2003 Elsevier B.V. All rights reserved.
