The similarity caching enables in-network caching nodes, e.g., a cache server, to return any similar contents, i.e., contents which is similar to the requested one, as well as an exact content, i.e., content exactly-matching the requested one. Through such a mechanism, users can obtain similar-contents from neighboring caches; the similarity caching is expected be to provide us more comfortable communication experience. However, the similarity caching might cause a problem regarding on the trade-off: which should we prioritize, the communication quality observed by users or the similarity between the requesting content and the actually-returned content? In this paper, to deeply understand the similarity caching on a general cache network, we formulate similar-content delivery delay as a user-centric performance metric for the similarity caching, and then, through several numerical examples, investigate characteristics of the similarity caching on a multi-stage cache network. As a consequence, we reveal, for instance, that the tendency of the similar-content delivery delay is dominated by the position of user, i.e., content requester, as well as the content similarity.","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":"2023-03-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"36","bibliographicVolumeNumber":"2023-IOT-60"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":224976,"links":{}}
