Abstract:Routing messages is an important problem in distributed networks, and efficient fault-tolerant routing requires methods to maintain shortest distances between nodes when faults occur. In this talk, I will introduce fault-tolerant versions of shortest path problems in graphs, and discuss algorithms and lower bounds for these problems in the "CONGEST" model of bandwidth-limited distributed computation. Specifically, I will present results for the Replacement Paths problem and the Distance Sensitivity Oracle problem which both deal with computing shortest paths in a graph when a single edge fails.
