(Virtual Private Network), which establishes secure connections between off-site clients and on-site servers, is getting important. In VPN, a part of network which is protected from the Internet is called “VPN domain.” In the environment where VPN domains are hierarchically configured (Hierarchical VPN), the next hop VPN gateway (VGW) must be discovered depending on the destination host. In this paper, we propose some routing methods which are transparent from users. In these methods, the next hop VGW is automatically discovered by querying to DNS servers and/or receiving ICMP and TCP packets. We have implemented proposed methods by extending the VTun software. The effectiveness of these methods are experimentally confirmed.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1096","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1090","bibliographicIssueDates":{"bibliographicIssueDate":"2008-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"49"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"Internet/LAN 運用管理技術"}]},"weko_creator_id":"1"},"id":9608,"updated":"2025-01-23T03:18:04.832252+00:00","links":{},"created":"2025-01-18T22:44:46.738281+00:00"}
