Some kinds of application need guarantee of throughput over wide area networks. Pipeline processing of large scale Grid computing and remote data backup over wide area network are typical example. Pipeline processing needs dispatches jobs to CPUs which are distributed to many places, and transfers data between CPUs over wide area network. Data transfer of remote backups transfers large amount of data during night. Data transfer of these applications should be done in time to follow the application schedule. Reservation of bandwidth is effective to transfer data in time. Usually, cost of service level agreement increases in proportional to reservation bandwidth. The method should reduce cost of these applications that decreases necessary bandwidth for guaranteeing throughput of data transfer. We propose the method that decreases reservation bandwidth in Diffserv AF network environments. Our method consists of dynamic QoS control method and data transfer protocol using two kinds of TCP connections. In this paper, we denote proposal method and its evaluation result.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"715","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"706","bibliographicIssueDates":{"bibliographicIssueDate":"2008-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"49"}]},"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":"ネットワーク品質・制御"}]},"weko_creator_id":"1"},"id":9656,"updated":"2025-01-23T03:16:44.213286+00:00","links":{}}
