However, although there are several proposals for leading clients to the most efficient server according to the constantly changing sever and network condition, as yet no definitive solution has been proposed. In this document, we propose a measurement method for dynamically changing server and network enviroment, a new selecting method to find the most efficient server based on the measurement method, and an efficient server selection system for leading the access clients to the most efficient server among the distributed Web server network. Under this method, we use AS (Autonomous System) path routing information of BGP (Border Gateway Protocol) as the factors for evaluating the logical distance of the network. We also try to determine the most efficient Web server by using various server/network information measurement tools. Experimental Web server sites have been set up in both Japan and the USA, and a prototype system was implemented on the Internet and its performance was evaluated; results of the experiments and evaluation are included in this report.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"12","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"7","bibliographicIssueDates":{"bibliographicIssueDate":"2000-07-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"62(2000-DSM-018)","bibliographicVolumeNumber":"2000"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T23:12:55.323399+00:00","id":47441,"links":{}}
