In contrast, Open Shortest Path First (OSPF) is a conventional routing protocol that performs automatic path selection based on link costs. In this study, a network degradation environment with increased delay and packet loss is constructed, and the path selection behavior and communication quality of OSPF and SRv6 are comparatively evaluated. Using the Mininet emulator, degradation is applied to specific links, and the behavior of OSPF when traffic traverses paths including degraded links is observed. For SRv6, paths are explicitly specified, and communication quality is evaluated in both cases where traffic traverses degraded links and where such links are avoided. Through these evaluations, the characteristics of automatic path selection and explicit path control are discussed.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2026-02-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"48","bibliographicVolumeNumber":"2026-IOT-72"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"created":"2026-02-16T07:20:14.545345+00:00","updated":"2026-02-16T07:51:27.354103+00:00"}
