Content is delivered on per reservation basis. After the reservation, the required content is stored in a cache connected with a ROF local station via optical fiber. When the designated time arrives, the content is delivered from the cache to a target terminal by way of the ROF local station in a high-speed manner. It can also be done by moving the content from the cache to another one depending on the target terminal location in a flexible way, even if the target terminal could not reach the place designated in the reservation. We implement a preliminary system from the viewpoints of 1) processing time from logging into the system for a reservation to delivering content to the target terminal and 2) amount of control traffic required for the deliver. The results emphasize the content delivery domain providing would be widely deployed as one of promising ITS service platforms. The paper is concluded with some future works toward more promising and practical system.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"66","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告高度交通システム（ITS）"}],"bibliographicPageStart":"59","bibliographicIssueDates":{"bibliographicIssueDate":"2002-03-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"21(2001-ITS-008)","bibliographicVolumeNumber":"2002"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
