Abstract
A connection-oriented network node capable of becoming an originating node of a protection path serving as a bypath of a protection segment included in a working path in a network system in which data is transferred via a path previously set up between nodes, comprises a usage bandwidth determining unit determining, when setting up the protection path, a usage bandwidth of the setup target protection path on the basis of a working path including the protection segment to be protected by the setup target protection path, and a generation unit generating, if a value obtained by adding the determined usage bandwidth to a current protection path usage bandwidth of an interface transmitting data that is forwarded on the setup target protection path, does not exceed a usable bandwidth for the protection path that is preset with respect to the interface, a signaling message for setting up the setup target protection path to send this message.
