Summary:We present a new algorithm which creates redundant trees on
arbitrary node-redundant or link-redundant networks. These trees are
such that any node is connected to the common root of the trees by at
least one of the trees in case of node or link failure. Our scheme
provides rapid preplanned recovery of communications with great
flexibility in the topology design. Unlike previous algorithms, our
algorithm can establish two redundant trees in the case of a node
failing in the network. In the case of failure of a communications link,
our algorithm provides a superset of the previously known trees
