ABSTRACT:
In a network including a simple element having no routing function, each node includes a health-check function to keep track of the respective statuses of its managing simple elements. A source node broadcasts an address request signal (TARP) including the ID of a destination simple element and then waits for its response signal. Each node, receiving the address request signal, further broadcasts it when neither managing nor normally communicating with the destination simple element, and otherwise sends the response signal back to the source node. When the response signal is received from another node, the source node transmits a management message to the destination simple element via the node sending the response signal. Since it is checked that each node normally communicates with its managing simple elements by the health-check function, the node cannot send the response signal in the case where some failure exists between the node itself and the destination simple element.
