ABSTRACT:
Only when a request formed of a plurality of request packets obtained by dividing the request is reconstructed, the request is transmitted to a survey target node that returns a response formed of a plurality of response packets obtained by dividing the response. When no response packet has been received at all from the survey target node, it is determined that any of the request packets has been discarded on a first route from a surveying node as a transmission source of the request to the survey target node. When one or more response packets have been received from the survey target node but the response cannot be reconstructed, it is determined that any of the response packets transmitted from the survey target node has been discarded on a second route from the survey target node to the surveying node as the transmission source of the request packets.
