Obstacle cause analysis system and obstacle cause analysis method of communication network, and program for obstacle cause analysis

摘要

As for the obstacle cause analysis system, cause of the obstacle in the communication network being the obstacle cause analysis system which presumes from record contents of internal processing of the communication device, the obstacle cause presumption expedient which presumes obstacle cause on the basis of the similarity of statistical feature of the aforementioned record contents which you acquire the past obstacle occurrence time when feature extraction expedient and the obstacle cause of extracting the statistical feature of the aforementioned record contents when occurring of obstacle are known and statistical feature of the aforementioned record contents which you acquire when occurring of obstacle, and, it has. Feature of obstacle and corresponding relationship during obstacle cause are acquired from the past obstacle case vis-a-vis the obstacle of the communication network which is detected from the process log inside the communication device, regardless of the multi of the case, the range of variation of feature is installed in judgment quantitatively, the obstacle cause analysis system of the communication network which can presume the source of obstacle is offered.
