Abstract
A method, implemented at a computer system in a network, for localizing network failure in the network includes enumerating at least one path between the computer system and a path destination node in the network through one or more intermediary nodes. The method further includes enumerating a plurality of sub-paths between the computer system and the path destination node. Each sub-path has either the path destination node, or one or more intermediary nodes of the corresponding path as a corresponding sub-path destination node. For each of the plurality of sub-paths, determining a probability that a data packet can successfully traverse the round trip of the corresponding sub-path and identifying a node in the network where network failure have occurred.
