PROBLEM TO BE SOLVED: To efficiently identify a path statically set in a network.SOLUTION: There is provided a communication path estimation method for estimating a communication path in a network in which communication is established by transferring packets from a plurality of transmission source nodes to a plurality of transmission destination nodes via a plurality of nodes.In the method, a computer acquires multiple pieces of path information for connecting the plurality of transmission sources to the plurality of transmission destination nodes based on the path information, and outputs information that a static path has possibly been set at a downstream-side node at a detected second abnormal point from a downstream-side node at a detected first abnormal point when a plurality of nodes are connected to the downstream of the downstream-side node at the detected first abnormal point, and an upstream-side node at the detected second abnormal point coincides with an upstream-side node at the first abnormal point. |
