Defined Network (SDN) is a technology that allows a software program called ”controller” to manage networks. This technology attracts much attention nowadays since it has many advantages such as dynamic and flexible network configuration. However, it may decrease the throughput of SDN controlled network especially when the controller deals with many packets such as fragmented packets since the overhead for the controller to process packets tends to be relatively large. In this paper, we focus on DNS amplification attack countermeasures using SDN. First, we point out a problem of an existing countermeasure which did not take fragmented packets into account and then propose an improved method to mitigate this problem.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2019-06-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2019-IOT-46"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:02:01.243852+00:00","updated":"2025-01-19T22:17:44.576804+00:00","id":197584}
