Abstract: In an example of the invention, network devices are classified into areas. Each of the areas includes edge nodes. A network management apparatus retains fault information including values each indicating whether or not a fault has occurred in each of the areas, retains detour path information including values indicating edge nodes, values indicating alternative areas to the areas and priorities assigned to the alternative areas, identifies, when determined that a fault has occurred in a first area based on the fault information, an alternative area to the first area based on the detour path information, determines, when determined that the fault has not occurred in the identified alternative area, the identified alternative area as a second area through which the active path passes, determines two edge nodes included in the second area, and detect network devices through which the active path passes between the two edge nodes.

Abstract: Provided is a communication device including a plurality of physical ports, the communication device holding information for associating each of at least one logical port and at least two physical ports, the communication device being configured to: identify, when any one of the plurality of physical ports receives data including user data, one of the at least one logical port as an output destination of the data based on destination information included in the received data; select, based on the data, one of the at least two physical ports associated with the identified logical port as an destination of the data; generate coupling check data relating to one of the plurality of physical ports; transmit the coupling check data from the one of the plurality of physical ports; and transmit data including the user data from the physical port selected by a first processing unit as the output destination.
