SVTP の設計では，無線リンクの短時間内の大きな変動に対する TCP の再送制御，輻輳制御の副作用による性能低下を懸念して，非 TCP のトランスポートプロトコルの使用を試み，これまでにトランスポート層に SRT（Secure Reliable Transport）を使用した実装を行なっている．一方で TCP のチューニングによる性能向上の試みに関しては十分に行われていなかった．本稿では，SRT ベースで開発・チューニングを行った SVTP（SVTP 2023）と，同実装のトランスポート層を TCP に変更した版（SVTP tcp）の性能比較を模擬下水管における実験に関して報告する．実験の結果，チューニングを行った TCP ベースの SVTP の方が，SRT ベースの SVTP と比べてスループットが高く維持され，また中継サーバでの受信可能データ量が多いことが確認された．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告ユビキタスコンピューティングシステム（UBI）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-02-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"24","bibliographicVolumeNumber":"2024-UBI-81"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":232628,"updated":"2025-01-19T10:23:10.027570+00:00","links":{},"created":"2025-01-19T01:33:36.410362+00:00"}
