Quality-deteriorated part analyzing system, quality-deteriorated part analyzing device, quality-deteriorated part analyzing method, and quality-deteriorated part analyzing program
Provided is a quality-deteriorated part analyzing system capable of analyzing a quality-deteriorated part in a network while increasing the degree of freedom of precision (coverage ratio, sectioning divisions, etc.) independently of the number and installation locations of devices transmitting and receiving flows. Path calculation means 71 determines paths, each passing through one or more directed links between nodes in the network and being regarded as a target of communication quality measurement, and generates a path table which indicates directed links included in each communication quality measurement target section. Quality measurement means 74 measures communication quality based on the flows corresponding to the paths determined by the path calculation means. Analysis means 75 analyzes a communication quality-deteriorated part in the directed links in the network based on the path table and the communication quality.
