Routing systems must offer a flexible interface to performance management systems in networks, which services must be guaranteed. Moreover, pro-active functionalities must also be incorporated in both systems in order to trigger actions before failure occurrences. This paper presents a pro-active re-routing architecture to forward streams through alternatives routes in which resources are available. These rerouting actions are taken when they are requested by performance management system. A prototype was implemented considering active and MPLS technologies. Preliminary testes allowed ascertaining the feasibility of the proposed architecture.
