We consider the problem of transmitting a message from a sender $s$ to a receiver $r$ through a network in which edges may fail and cannot recover. In the transmission protocols we consider, we require that $r$ may not be “flooded” by infinitely many copies of this message. A routing protocol is $k$-robust if it ensures that a message sent by $s$ will be received by $r$ when at most $k$ edges fail, unless no $s,r$-path remains. Graphs which have a $k$-robust protocol for all $k$ were characterized in [F. E. Fich, A. Kündgen, M. J. Pelsmajer, and R. Ramamurthi, SIAM J. Discrete Math., 19 (2005), pp. 815-847]. For any other graph, its robustness is the maximum $k$ for which it has a $k$-robust protocol. We provide general lower bounds for robustness by improving a natural protocol obtained from Menger's theorem. We determine robustness for several examples, such as complete graphs, grids, and hypercubes.
