摘要： A method for providing a protected fast rerouting scheme for traffic conveyed in a network comprising a working path and a first backup path for conveying the traffic in case of a node failure. The method enables conveying traffic when two simultaneous failures occur, a failure of a link and/or of a node, belonging to the working path and the other—a failure occurring at a link and/or a node belonging to the first backup path. Upon detecting occurrence of a link/node failure along the working path, traffic is diverted to the first backup path, and upon detecting a concurrent failure at the downstream link/node at the first backup path, traffic is diverted to a second backup path extending from a node belonging to the first backup path and merges with the working path at a node located downstream of the failure that occurred at the working path.
