Fault recovery is a key issue in modern data centers. In a fat tree topology, a single link failure can disconnect a set of end hosts from the rest of the network until updated routing information is disseminated to every switch in the topology. e time for re-convergence can be substantial, leaving hosts disconnected for long periods of time and signi cantly reducing the overall availability of the data center. Moreover, the message overhead of sending updated routing information to the entire
