Abstract
A method for detecting a topology change in a communication network. The method includes measuring a minimum latency value of a communication between two devices in the communication network for each of a plurality of time cycles, identifying an increase in the minimum latency values among the plurality of time cycles, and detecting a topology change in response to a determination that the increase in minimum latency values is maintained for more than a predetermined number of time cycles.
