Example failure scenarios include unintentional failures due to scheduled maintenance activities or massive failures caused by disaster\u2010induced events. Therefore, it is crucial to enhance the networks with redundancy and resilience mechanisms able to maintain the availability of network services after a failure. As these problems are often inherently hard to solve to optimality, the role of time\u2010efficient approximation schemes is essential.
