Streaming capacity for a channel is defined as the maximal streaming rate that can be received by every user of the channel. In this paper, we study the streaming capacity problem in multi-channel P2P VoD systems. In an independent-channel P2P VoD system, there is no resource correlation among channels. Therefore, we can find the average streaming capacity for the independent-channel P2P VoD system by finding the streaming capacity for each individual channel, respectively. We propose a distributed algorithm to solve the streaming capacity problem for a single channel in an independent-channel P2P VoD system. The average streaming capacity for a correlated-channel P2P VoD system depends on both the intra-channel and cross-channel resource allocation. To better utilize the cross-channel resources, we first optimize the server upload allocation among channels to maximize the average streaming capacity and then propose cross-channel helpers to enable cross-channel sharing of peer upload bandwidths. We demonstrate in the simulations that the correlated-channel P2P VoD systems with both intra-channel and cross-channel resource allocation can obtain a higher average streaming capacity compared to the independent-channel P2P VoD systems with only intra-channel resource allocation.<\/jats:p>","DOI":"10.1155\/2012\/807520","type":"journal-article","created":{"date-parts":[[2012,2,29]],"date-time":"2012-02-29T21:01:17Z","timestamp":1330549277000},"page":"1-9","source":"Crossref","is-referenced-by-count":1,"title":["Improving Streaming Capacity in Multi-Channel P2P VoD Systems via Intra-Channel and Cross-Channel Resource Allocation"],"prefix":"10.1155","volume":"2012","author":[{"given":"Yifeng","family":"He","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Ryerson University, Toronto, ON, Canada M5B 2K3"}]},{"given":"Ling","family":"Guan","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Ryerson University, Toronto, ON, Canada M5B 2K3"}]}],"member":"98","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2007.070112"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2011.2145630"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/TCSVT.2010.2077553"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/TMM.2009.2012921"},{"key":"21","year":"2001"},{"issue":"8","key":"24","doi-asserted-by":"crossref","first-page":"1439","DOI":"10.1109\/JSAC.2006.879350","volume":"24","year":"2006","journal-title":"IEEE Journal on Selected Areas in Communications"},{"key":"22","year":"2004"},{"key":"23","year":"2003"}],"container-title":["International Journal of Digital Multimedia Broadcasting"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2012\/807520.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2012\/807520.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2012\/807520.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,20]],"date-time":"2017-06-20T15:00:20Z","timestamp":1497970820000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/ijdmb\/2012\/807520\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":8,"alternative-id":["807520","807520"],"URL":"https:\/\/doi.org\/10.1155\/2012\/807520","relation":{},"ISSN":["1687-7578","1687-7586"],"issn-type":[{"value":"1687-7578","type":"print"},{"value":"1687-7586","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012]]}}}
