However, since SDN basically decides how to process incoming packets based on information of layers 4 or less, server selection according to layer 7 information such as command argument cannot be performed. In this paper, to enable such flexible traffic control, we propose a host altering function required after TCP connection establishment in OpenFlow. With this function, on receiving the connection establishment request from the client, it is possible to monitor the payload of communication after establishing a connection with one server, and alter the server according to the payload.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"31","bibliographic_titles":[{"bibliographic_title":"インターネットと運用技術シンポジウム論文集"}],"bibliographicPageStart":"24","bibliographicIssueDates":{"bibliographicIssueDate":"2018-11-29","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2018"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-20T00:03:10.502260+00:00","created":"2025-01-19T00:58:21.457396+00:00","links":{}}
