To provide dependable services, IP\MPLS networks make use of a set of procedures (detection, notification and fault recovery) which is used to ensure appropriate protection for the traffic carried in the LSPs. One of the basic recoverymodels used to redirect traffic is the protection switching. In this paper we focus on the fault recovery issue in protection switching and use a priority–based scheme to overcome the link\node failures that may happen in an active LSP. By considering an IP\MPLS network as an infrastructure in a Smart Grid, and giving priority levels to all the incoming requests from the grid, we show that resources are used more efficiently and an adequate QoS can be achieved.<\div>

To provide a reliable backbone network, fault tolerance should be considered in the network design. Multiprotocol label switching (MPLS) based backbone network, is used to provide traffic engineering (TE) and high speed networking. The fault–tolerant issue which is one of the aspects of QoS, focuses on how to protect the traffic of a label switched paths (LSP) against node and link failures. Fault tolerance techniques are very useful to maintain the survivability of the network by recovering from failure within acceptable delay and minimum packet loss while efficiently utilizing network resources.In this paper, based on the modified (k, n) threshold sharing scheme with multi–path routing, we propose a relationship between k and n by considering the priority levels of incoming traffics, we apply a congestion method to reduce the packet loss. The traffics that are going to be injected to our IP\MPLS network are received from a Smart Grid sub–networks. The approach introduces very low recovery delay and low packet loss while giving desirable throughput of the network. In addition, it can easily handle single and multiple path failures. We validate the analytical results through simulations in OPNET.<\div>
