a large-scale disaster occurs, the information sharing functionality among the administrators, the residents and volunteers is important. However, there were many cases where information sharing was not actually well functioned because the disaster information network infrastructure did not consider the system failure when the disaster happened. In our research, we focus on the fact that the disaster information systems are operated on each local area. The system redundancy is realized by sharing the system resources and integrating the disaster information into a large disaster system while decentralizing the system and network loads. And, the system failure can be recovered by introducing system failure detection function for server failure and link disconnection and dynamically reconstructing the network system. In order to verify the usefulness of the suggested method, we constructed a nation wide disaster information network prototype system over Japan Gigabit Network (JGN2), implemented Wide-area Disaster Information Sharing system (WIDIS) and evaluated its functionality and performance.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2350","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2340","bibliographicIssueDates":{"bibliographicIssueDate":"2007-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"48"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"ネットワークサービス"}]},"weko_creator_id":"1"}}
