Furthermore, to cope with disasters, the system is useful as the alternative links of submarine optical fiber links. However, the existing researches have not evaluated the HTTP (HyperText Transfer Protocol) performance on such multi-hops system both theoretically and experimentally. Therefore, we evaluate web data transfer time based on HTTP over the multi-hops satellite communication system. Firstly, we propose a new formula for the HTTP1.1 performance over the system, Secondly, we also propose a formula taking pipeline requesting into account. Finally, the calculation results are compared with the experimental ones based on the SKYCAST system, which is one of the multi-hops satellite communication systems. As a result, it is shown that the values based on the evaluation formulas are close to those from the experimental results.","subitem_description_type":"Abstract"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_3_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110006382841","subitem_relation_type_select":"NAID"}}]},"item_3_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"情報処理学会"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ipsj.or.jp/","subitem_relation_type_select":"URI"}}]},"item_3_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意：本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。"},{"subitem_rights":"The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
