<p>Erroneous detection of a failure in spite of the absence of failure on the route on account of a communication delay is to be prevented. A node device detects a failure on the route to a remote node device is detected by a failure to receive a packet from the remote node device after the elapse of a determined detection time. The node device sets“remote system transmission interval×detection multiplier”to be a first detecting time on the basis of a packet transmission interval determined by negotiation with the remote node device. It also sets the sum of“remote system actual transmission interval ×detection multiplier”and“tolerable delay time”to be a second detecting time. The first detecting time and the second detecting time are compared, and what is longer is determined as the detecting time to be applied to actual operation.</p> |
