Protection trees have been used in the past for restoring multicast and unicast traffic in networks in various failure scenarios. In this paper, the authors focus on shared self-repairing trees for link protection in unicast mesh networks. Shared protection trees have been proposed as a relatively simple approach that is easy to reconfigure and could provide sub-second restoration times with sub-optimal redundancy requirement. The self-repairing nature of this class of protection trees may make them an attractive option for cases where dynamic changes in network topology or demand may occur. In this paper, they present heuristic algorithms to design a self-repairing protection tree for a given network
