The plethora of new technologies and services such as MPLS, ATM, IP, SONET and WDM allows services to be restored at different layers and at different costs. Restoration schemes at multiple layers might collide, causing a race condition, where restoration agents at different layers keep trying to establish a connection. We define a model for restoration mechanisms at different layers and discuss a technique for automatically detecting conflicts. Our algorithm might be applied as a test before a failure occurs.
