Abstract
A processing system may obtain network connectivity test results, each indicating success or failure of a network connectivity test between a respective router pair from a plurality of routers of the communication network. The processing system may identify, from the connectivity test results, a burst of network connectivity results indicating network connectivity test failures, and identify, from the connectivity results, a subset of connectivity test results indicating failures from within a time period associated with the burst. The processing system may further determine, for each connectivity test result in the subset, connectivity path information including one or more routers between a router pair of the connectivity test result. The processing system may then determine, from the connectivity path information of the subset, a router with a highest number of occurrences, and may identify the router as a cause of a soft failure in the communication network.
