this paper, we propose a real-time packet scheduling method that enables the low latency packet forwarding for the real-time bi-directional continuous media communication on a LAN including cascaded

The experimental implementation of the packet scheduler can reduce the maximum latency in the single router to be less than twice the period of the isochronous transfer without any packet loss for a real-time stream. The packet scheduler can also reduce the maximum latency of cascaded routers to be less than the period of the isochronous transfer multiplied by the number of hops plus one with heavy background traffic.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"178","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"165","bibliographicIssueDates":{"bibliographicIssueDate":"2007-05-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG8(ACS18)","bibliographicVolumeNumber":"48"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T22:51:02.610348+00:00","updated":"2025-01-22T22:53:03.339855+00:00","id":18263}
