Abstract	With the diversification of the traffic carried on the Internet, improvement of QoS has become very demanding in order to realize large capacity, high speed and reliable communication in IP networks. Various models have been proposed to address this need, MPLS being one of the main architectures, having the broadest deployment on the Internet to achieve these QoS goals. It is expected that, in the future, congestion and faults on a label switched path (LSP) will seriously affect service contents, and recovery and restoration of such LSPs would be required to realize a fault-tolerant MPLS network. In this context, researchers in the past have addressed the need with respect to intermediate link and/or node failures. Our main concern is to provide the solution for an ingress label edge router (LER) failure, as this is the node at the very first stage of the LSP. We consider both partial ingress LER failure where only the control plane of the ingress node fails, and total ingress failure resulting in node replacement. Intermediate link and/or node failure is reviewed in the context of ingress LER failures.
