Consider a network of asynchronous processors communicating by sending messages over unreliable lines. There are many advantages to restrict all communications to a spanning tree. To overcome the possible failure of k<k edges, we describe a communication protocol which uses k rooted spanning trees having the property that for every vertex v the paths from v to the root are edge-disjoint. A linear algorithm to find two such trees in a 2 edge-connected graph is described. This algorithm has a distributed version which finds the two trees even when a single edge fails during their construction. Finally, a method is given to transform centralized algorithms to distributed, reliable and efficient ones.
