PROBLEM TO BE SOLVED: To provide a route specifying method and device, and a route specifying program, by which a processing load can be reduced when specifying three or more different routes which do not share a link/node on a way of the route connecting two nodes.SOLUTION: The method includes: specifying k route-containing closed routes (C200+C400, C300) which pass an arbitrary first node (N300) and second node (N500) and do not intersect each other based on the closed route closed by a plurality of nodes and links in a network; and specifying different (k+1) routes between the first node and the second node from the route-containing closed route. |
