to make applications cloud-native, but this architecture can easily increase the number of communications, which lead to lower latency and increased load on the communication software. This paper proposes full offloading of OVS (Open vSwitch) communication software using NVIDIA BlueField, which can offload not only communication packet processing but also its management processing to the hardware, and realize low latency by hardware offload while reducing processing load of OVS at the host to zero. We also propose direct forward for intra-node communication where the latency is degraded by offloading itself. The full offload was designed from Antrea, an OVS-based CNI (Container Networking Interface) plug-in, and reduces latency by up to 55% with direct foward for intra-node communications and up to 57% with full offload for inter-node communications.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-07-13","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2021-OS-153"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":211861,"links":{}}
