Abstract (in Japanese) (See Japanese page) 
(in English) It’s difficult for network operators to assure Quality of Services which are required very high bit rate and low packet loss rate such as Video Streamings or Video Conferences in the best-efforted IP network services such as the Internet. Many researchers have handled that the framework of flow quality degradation detection by monitoring the flows and the framework of inferring the flow degradation point when quality degradation occurred hitherto.
The aim of our research are detection of network (itself) quality degradation and inferring the network (itself) degradation point when some segments have troubles to occur the quality degradation. When we assume the full wired and wireless mixed network such as FMC (Fixed Mobile Convergence), it’s difficult to detect the network quality degradation in this network. In this paper we propose a network quality degradation detection method which features are inferring how many wireless segments are contained by using network characteristics and then to decide to change degradation detection algorithm for reduce false positive and false negative when there are wireless segments, and show the result of our proposed method.
