Abstract (in Japanese) (See Japanese page) 
(in English) In network operations, management of topology information is essential for accurately identifying devices with failures. To achieve this, changes in network topology caused by frequent configuration updates and device failures must be reflected.
However, conventional topology management relies on manual updates, which makes it difficult to promptly incorporate such changes.
In this paper, we propose a method to estimate the latest topology information due to change factors by analyzing the causes of topology changes based on device alarm information and comparing latest topology data with previous topology data.
