Abstract:
A first confirmation unit performs a first confirmation of confirming presence of a connection to a correspondent node in a first communication layer, presence of a connection to a correspondent node in a second communication layer, and presence of a connection to a correspondent node in a third communication layer. A locating unit locates a failure point in communication based on a result of the first confirmation. An output unit outputs a result of the location.
