<p><P>PROBLEM TO BE SOLVED: To enable high-precision and high-speed quality-deteriorated portion estimation. <P>SOLUTION: A network quality-deteriorated portion estimating apparatus includes a flow quality information collector 11 for collecting flow quality information containing a transmitter's address of a flow performed by a network user, a receiver's address, and communication quality; a route information collecting means 12 for collecting information on an architecture of the network; a flow quality and flow going through link table management 13 and a table storage 14 that determines a link passed by the flow and besides judges whether flow quality has been deteriorated or not, based on collected flow quality information and the information on the architecture of the network to manage the judged results as a table; and a quality-deteriorated portion estimator 15 for outputting a partial aggregate having the smallest elemental number from among a partial aggregates, containing the link passed by an arbitrary quality-deteriorated flow among the partial aggregates of the links passed by the arbitrary quality-deteriorated flow aggregate, when there have occurred quality deteriorations in one or more flows in the table managed. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
