クラスタなどによる構成方法が一般的であるが，分散配置したサーバには適していない．また，通信のボトルネックや単一障害点になりやすいなど，物理的な構成上の制約がある．そこで，本論文では，IP alias と経路情報によって anycast を行い，分散配置した複製サーバを冗長化する構成方法を提案する．この構成方法では，仮想 IP アドレスの経路制御によって冗長化を行うことにより，フェイルオーバ構成でも負荷分散構成でも動作することができる．また，ロードバランサなどの新たな装置や機器の導入が必要ないというメリットもある．提案方法に基づき試作システムで運用した結果，実用的に動作することが確認された．","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"Recently, most of social activities depend on a information system, and the service continuity of the information system has become very important. For redundant configuration of the computer system, High-Availability cluster system is generally used. However this system is not suitable for the distributed replica servers since it may become a bottleneck of communication and ”Single Point of Failure”, and there are also restrictions on the physical configuration. In this paper, we propose a configuration method which makes the distributed replica servers redundant by means of anycast using IP alias and IP routing. In this method, since the redundancy function is performed by IP routing of the identical virtual IP address, it can be configured both failover configuration and load-balancing configuration. This method also have a merit that does not require an equipment such as a load balancer. According to a field testing, we confirmed the proposed system worked effective and practical.","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":"2012-06-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2012-IOT-18"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:36:28.081537+00:00","updated":"2025-01-21T18:55:16.552907+00:00","id":82633}
