Ethernet is becoming a preferred technology to be deployed in metro domain due to its low cost, simplicity and ubiquity. Nevertheless, Ethernet was originally designed as a LAN technology; therefore, it lacks fast fault-protection which is very important in the new real-time applications. On the other hand, most of the failure recovery algorithms proposed in literature are offline in nature or they are very complex to be used in Ethernet networks. In this paper, we propose an Online Fast Failure Recovery Strategy (OFFRS) to find the best redundant paths with minimum cost for each protected link. OFFRS is a simple, fast and online approach useful to be applied in metro Ethernet networks. Simulation results will show the effectiveness of OFFRS.
