<p>A data collection device stores, in a message, a source route which designates a path through which the message, which is transmitted to a destination node (1-h), is routed. A node which receives the message transfers the message on the basis of the source route which the received message stores. If a link error is detected between a node (1-c) and an adjacent node, the node (1-c) sets and floods a TTL to a local restore message in which the destination node (1-h) which the message does not reach due to the link error is a subject to be searched, and notifies the data collection device of a restoration path from the node (1-h) to the host device on the basis of the response to the local restore message.</p> |
