<p><P>PROBLEM TO BE SOLVED: To reduce an enormous work cost that a network administrator bears. <P>SOLUTION: Only when a request is reconstructed, the request being formed of a plurality of request packets obtained by dividing the request, the request is transmitted to a survey target node that returns response packets obtained by dividing a response. When no response packet has been received at all from the survey target node, determination processing is carried out to determine 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 can not be reconstructed, determination processing is carried out to determine 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. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
