Abstract
A network management device retains path information of paths as a list of node identifying information to identify nodes, the path information including information on paths sharing a link regarding a relation in which one path shares a link with another path. According to the information on paths sharing a link, the network management device determines a path setup timing for a path to be the same for a group of one or more paths that do not share a same link with the path and determines a different path setup timing for a group of one or more paths that share a same link with the path than the timing for the group including the path, and executes path setup via communication devices existing on paths constituting each group of paths as per path setup timing determined for each group.
