BigchainDB が提案されている．BigchainDB は，スケーラピリテイが高く，分散されているが，分散データベースの性能に依存しているため，今後 IoT デバイスの数が急激に増加すると，データベースの性能が低下してしまう可能性がある．そこで本論文では，FPGA NIC 上にキャッシュを作成し，DB サーバで行う処理の一部をオフロードすることでデータベースの性能を向上させることを目的とした．評価では，サーバまたは FPGA NIC が 1 秒間に処理できたクエリ数を計測し，スループットを算出した．またサーバ上に擬似的なソフトウェアキャッシュを作成することで，提案手法による貢献を分析した．具体的にはデータベースがクエリを処理する遅延の削減によりスループットは平均で 1.8 倍向上し，クエリがネットワークを通過する通信遅延の削減によりスループットは平均で 3.8 倍向上した．さらにシステム全体のスループットは平均して 6.9 倍向上した．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システム・アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2017-07-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"29","bibliographicVolumeNumber":"2017-ARC-227"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-20T03:55:56.998706+00:00","created":"2025-01-19T00:50:24.250176+00:00","links":{},"id":182830}
