We ran two computer simulations: (i) only the packet scheduling algorithms were applied, and (ii) both the packet scheduling algorithms and a media synchronization control were applied. Results showed that in case (i), a high application—level QoS with a relatively low delay was achieved when the WFQ was applied to congested nodes and to the node next to the media senders. In case (ii), a high QoS was achieved independently of the arrangement of WFQ nodes only if the bandwidth requirement was satisfied at the congested nodes.","subitem_description_type":"Other"}]},"item_10001_description_38":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"Takeo, Jun"}]},{"nameIdentifiers":[{}],"names":[{"name":"Tasaka, Shuji"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"映像情報メディア学会"}]},"item_10001_relation_34":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.3169/itej.63.1306"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.3169/itej.63.1306","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_35":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10025987027"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/10025987027","subitem_relation_type_select":"NAID"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13426907","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"書誌レコードID（NCID）","attribute_value_mlt":[{"subitem_source_identifier":"AN10588970","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"竹尾, 淳"},{"creatorName":"タケオ, ジュン","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田坂, 修二"},{"creatorName":"タサカ, シュウジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-04-25"}],"displaytype":"detail","filename":"TasakaShuji_2009_P1.pdf","filesize":[{"value":"9.6 MB"}],"format":"application/pdf","license_note":"(C)2009 映像情報メディア学会","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/5936/files/TasakaShuji_2009_P1.pdf"},"version_id":"a11a2d61-fed3-4430-9b48-cd93bb5dec37"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"音声・ビデオIP伝送","subitem_subject_scheme":"Other"},{"subitem_subject":"ストリーミング","subitem_subject_scheme":"Other"},{"subitem_subject":"WFQ","subitem_subject_scheme":"Other"},{"subitem_subject":"スケジューラ配置","subitem_subject_scheme":"Other"},{"subitem_subject":"アプリケーションレベルQoS","subitem_subject_scheme":"Other"},{"subitem_subject":"メディア同期","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"音声・ビデオストリーミングIP伝送のアプリケーションレベルQoSを向上するWFQスケジューラの配置","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"音声・ビデオストリーミングIP伝送のアプリケーションレベルQoSを向上するWFQスケジューラの配置"},{"subitem_title":"Arrangement of WFQ Schedulers for Enhancement of Application-level QoS in Audio-Video Streaming IP Transmission","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["31"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-25"},"publish_date":"2017-04-25","publish_status":"0","recid":"5936","relation_version_is_last":true,"title":["音声・ビデオストリーミングIP伝送のアプリケーションレベルQoSを向上するWFQスケジューラの配置"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-16T14:32:04.332909+00:00"}
