In this paper we propose and evaluate the efficiency of a location-based restoration mechanism in a dynamic multi-domain GMPLS network. We focus on inter-domain link failures and utilize the correlation between the actual position of a failed link along the path with the applied restoration technique. Our results show, that without violating the strong privacy preservation requirements between domains, the proposed mechanism has improved performance in terms of successfully restored connections compared to the traditional local-to-egress and end-to-end restoration approaches. Furthermore, the applied technique improves the availability of the connections by minimizing the restoration time.
