Abstract	In a multi-service IP network, it is a key challenge to provide QoS to end-user applications while effectively using network resources. Traffic Engineering support in MPLS networks allows operators to carry traffic with strict QoS requirements by means of advanced network capabilities, such as resource reservation, fault-tolerance and optimization of transmission resources. To deliver a reliable service, MPLS exploits a set of procedures that protect the traffic flows carried on different paths. Therefore, Label Switching Routers have to support mechanisms for fault detection, notification and recovery, whereas MPLS has to enable the configuration of different recovery techniques. In this paper, we present the design and the development of some software modules for the simulation of different MPLS-based recovery strategies in the discrete event simulator NS2. Moreover, the paper discusses some simulation results that show a performance comparison between path protection and path restoration strategies in a simulation scenario matching the Geant network.
