简介：遮蔽下载服务，作为脱机下载请求的内容并且在云存储保留它直到用户们检索它的新应用，最近成为了在中国吸引百万个用户的一个趋势。在面临在下载请求和存储资源的限制的生长之间的窘境时，云服务者不得不设计一个有效资源分配计划提高存储的利用以及满足象一短下载时间一样的用户需要。当用户搅拌机行为被看作一个Markov链过程时，下载速度的合适的分配能优化存储资源利用，这被发现。因此，二动态资源分配策划包括切换的速度(SS)增加的计划和速度(SI)策划被建议。理论分析和模拟结果证明我们的计划能有效地减少存储资源的消费并且为好用户经验使下载时间足够短。

简介：录像加速器在分享象YouTube那样的网站的录像为更好的用户经验被开发。PPLive录像加速器(PPVA)在中国有用户的最大的数字，基于对等(P2P)系统。在PPVA的录像和同伴的数字由比哪个多次大的数量级在需求(VoD)上的传统的P2P录像系统。作为结果，尽管资源是足够的，由于不公平赋值，服务的质量几乎不能满足所有用户。在这份报纸，我们在PPVA专注于基本资源的任务：存储和带宽。存储赋值的问题作为一个随机的变量关于请求的数字作为一个非线性的程序(NLP)被提出。当平均数比变化大得多时，请求的变化的影响不是可以忽略、比例的途径的结果表演仅仅是适当的。关于怎么定位录像到适当同伴的标准也被介绍，考虑抑制例如全部的带宽，带宽竞争的概率和在录像之间的公平的利用。而且，分配的启发式的算法以集中、分布式的时尚上载带宽被建议并且在录像之中关于平衡与广泛地使用的策略(相等的分配)作比较。模拟结果证明两个算法能导致重要表演改进。
