Many internet service providers have considered the use of cache servers on their networks as a solution to reduce the traffic. Existing schemes often periodically calculate a sub-optimal allocation of the content caches in the network. However, such approaches require a large computational overhead that cannot be amortized in a presence of frequent changes of the contents’ popularities. This paper proposes a light-weight scheme for a cooperative caching that obtains a sub-optimal distribution of the contents by focusing on their popularities. This was made possible by adding color tags to both cache servers and contents. In addition, we propose a hybrid caching strategy based on Least Frequently Used (LFU) and Least Recently Used (LRU) schemes, which efficiently manages the contents even with a frequent change in the popularity. Evaluation results showed that our light-weight scheme could considerably reduce the traffic, reaching a sub-optimal result. In addition, the performance gain is obtained with a computation overhead of just a few seconds. The evaluation results also showed that the hybrid caching strategy could follow the rapid variation of the popularity. While a single LFU strategy drops the hit ratio by 13.9%, affected by rapid popularity changes, our proposed hybrid strategy could limit the degradation to only 2.3%.","subitem_description_type":"Abstract"}]},"item_10003_version_type_43":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakajima, Takuma","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshimi, Masato","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wu, Celimuge","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshinaga, Tsutomu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-30"}],"displaytype":"detail","filename":"tnakajima-candar16-with-copyright.pdf","filesize":[{"value":"191.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tnakajima-candar16-with-copyright.pdf","url":"https://uec.repo.nii.ac.jp/record/7002/files/tnakajima-candar16-with-copyright.pdf"},"version_id":"7f96b2c2-c928-454b-becd-5d2e3d435e03"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"cooperative caching","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sub-optimal content placement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hybrid caching","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"dynamic content popularity.","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"A Light-weight Content Distribution Scheme for Cooperative Caching in Telco-CDNs","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Light-weight Content Distribution Scheme for Cooperative Caching in Telco-CDNs","subitem_title_language":"en"}]},"item_type_id":"10003","owner":"13","path":["2"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-11-30"},"publish_date":"2016-11-30","publish_status":"0","recid":"7002","relation_version_is_last":true,"title":["A Light-weight Content Distribution Scheme for Cooperative Caching in Telco-CDNs"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-08-04T08:01:50.864600+00:00"}
