A transmitting apparatus in a network constituted of a plurality of rings connected via a plurality of routes includes a node type determining unit and a backup path setting message transmitting unit. The node type determining unit determines, on receipt of a working path setting message requesting to set a working path, whether the transmitting apparatus is any one of a branch node at which a backup path is branched off from the working path or a merge node at which the backup path merges into the working path. The backup path setting message transmitting unit transmits, when the transmitting apparatus is determined to be a branch node or a merge node, a backup path setting message specifying a route from a ring including the transmitting apparatus to a connection node connecting the ring and a neighboring ring.
