To solve this problem, multi-home network have been researched and developed. Multi-homed networks can improve load balancing and reliability by using multiple network interfaces and connecting to the Internet through multiple paths. Since TCP does not support multi-homed network, it is necessary to use MPTCP, an extension of TCP, to take advantage of multi-homed network. However, MPTCP also falls back to TCP communication when it is not installed on both communicating terminals. Therefore, in the previous study, a VPN server was installed between the client and the server, and a network using MPTCP between the client and the VPN server was proposed. One of the problems that can occur in a multi-homed environment using VPN is the HOL blocking problem. In this paper, we confirm HOL blocking and propose bicast a method to mitigate HOL blocking. Comparative experiments in a virtual environment confirmed that HOL blocking occurs on multi-homed environment with VPN. We also found that bicast is effective in mitigating HOL blocking.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","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":"2024-05-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2024-IOT-65"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:35:57.899142+00:00","id":234239,"links":{}}
