Fault Isolation (SFI)を用いたNFVフレームワーク，XenFlowを提案する．スループットを評価した結果，SFIを用いたXenFlowはドメインベースの手法を用いたNFVフレームワークと比較し，Deep Packet Inspectionでは2.07-40.5%，Virtual Private

is being conducted on a Network Function Virtualization (NFV) framework that enables low-cost and flexible operation of network services by implementing NF as software (VNF) on general-purpose servers. An NFV framework should achieve packet zero-copy for high performance, which is realized by sharing a packet buffer among VNFs. In addition, considering a multi-tenant environment, an NFV framework must impose access control on a shared packet buffer to the VNFs, which can be achieved using the intra-process memory isolation technique. In the NFV framework as our previous work, we utilized a domain-based approach within intra-process memory isolation methods, but faced notable overhead and it places restrictions on VNF logic. This paper proposes XenFlow, an NFV framework that employs Software Fault Isolation, an alternative intra-process memory isolation technique, for a shared packet buffer access control. The evaluation results of throughputs show that XenFlow reduces the overhead by 2.07 - 40.5% for Deep Packet Inspection and 14.3 - 23.2% for Virtual Private Network endpoints compared to the NFV framework using the domain-based approach. Furthermore, the XenFlow mitigates the restrictions on VNF logic.","subitem_description_type":"Other","subitem_description_language":"en"}]},"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":"2025-02-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"58","bibliographicVolumeNumber":"2025-IOT-68"}]},"relation_version_is_last":true,"weko_creator_id":"80578"}}
