Depending on the predicted future load average, this proposed system adds or deletes the address of a mirror server that is included in a load distribution server list. In case the load average exceeds a defined maximum threshold, the system adds one server to the server list. On the other hand, one server is deleted if the predicted loads are below a minimum threshold. The loads of server are collected through snmp, and the future loads are inferred by least-square method. If the growth rate of load data is steep, a high spec mirror server is assigned. If the growth rate is moderate, a low spec mirror server is assigned. By this load distribution system, sudden increases of load are predicted, and the concentration of load on one server which is assigned by redirection can be reduced.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15029/00000499","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11155514","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Information Sciences, Faculty of Informatics, Department of Information Systems, Undergraduate Student"},{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Information Sciences, Faculty of Informatics, Department of Information Systems"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"東京情報大学総合情報学部情報システム学科学部学生"},{"subitem_text_language":"ja","subitem_text_value":"東京情報大学総合情報学部情報システム学科"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-03-01"}],"displaytype":"detail","filename":"KJ00008985499.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","license_note":"TUIS","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00008985499","url":"https://tuis.repo.nii.ac.jp/record/502/files/KJ00008985499.pdf"},"version_id":"49854067-3b6c-469a-aa98-507d2c5b40aa"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"動的負荷分散","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ミラーリング","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"snmp","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"最小二乗法","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"dynamic load balancing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mirroring","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"snmp","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"least-square method","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"未来負荷予測を考慮した動的なミラーサーバ提供システム","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"未来負荷予測を考慮した動的なミラーサーバ提供システム","subitem_title_language":"ja"},{"subitem_title":"Dynamic Server Mirroring System Using Load Change Rate Prediction","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["137"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-03-01"},"publish_date":"2014-03-01","publish_status":"0","recid":"502","relation_version_is_last":true,"title":["未来負荷予測を考慮した動的なミラーサーバ提供システム"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-12-22T00:29:50.079306+00:00"}
