<p><P>PROBLEM TO BE SOLVED: To provide a transmitting apparatus and a path setting method for setting, in a self-controlling mode, a backup path for protecting connecting portions between rings based on the small amount of data. <P>SOLUTION: The transmitting apparatus 10 included in the network constituted by connecting a plurality of rings with a plurality of paths is provided with a node class determining unit 13c for determining whether the relevant transmitting apparatus is in a branching node for branching the backup path extended via other path connecting the rings from the working path or in the merging node for merging the backup path to the working path when the working path setting message to request the setting of the working path is received, and a backup path setting message transmitting unit 13e for transmitting a backup path setting message setting the path to the connecting node as one of the nodes to connect the rings to which the relevant transmitting apparatus belongs and the rings adjacent to the relevant rings when the relevant transmitting apparatus is determined to be in the branching node or merging node. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
