<p><P>PROBLEM TO BE SOLVED: To provide a device for estimating the position of a deterioration capable of estimating the deterioration by discriminating a link and a node. <P>SOLUTION: Each element storing topology information and configuring paths, through which packet information passes, on the basis of the packet information transmitted by a terminal in a communication network is decided on the basis of the packet information and the topology information. The deterioration values of the paths, through which the packet information passes, are decided on the basis of the pairs of the packet information acquired in each of the transmission origin side and the transmission destination side. Each element configuring the paths and the deterioration values are associated with each other for every path in the communication network, through which the packet information passes, and stored in a deterioration information table. All elements associated with the deterioration values equal to or smaller than a deterioration decision threshold and recorded on the deterioration information table and the elements in the paths of other packet information matching the elements are decided as non-deterioration elements by using the deterioration decision threshold deciding deterioration or non-deterioration. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
