多媒体服务中间一公里资源优化

Focus on the Middle Mile of P2P-CDN

重点关注如何实现中间一公里处的多媒体有效分发.为此,文章首先利用博弈论分析了多媒体分发网络的内容分发与底层基础网络流量间的相互影响关系,提出一种中间一公里资源优化分配策略.在此基础上,文章提出一种新的动态资源分配算法并利用Matlab实验验证该算法的有效性.实验结果表明,与传统的冗余路由策略相比,动态资源分配算法能够将资源均匀有效的分配到整个网络中去,不仅能够优化多媒体分发网络中间一公里传输效率,还能优化底层基础网络资源分配.

This paper focused on how to deliver Multimedia in the middle mile effectively.Firstly,analyzing the interaction between content delivery and traffic engineering with the Game Theory.Proposed a resource allocation strategy for the Multimedia delivery in the middle mile,which takes into account the physical background traffic and the work state of Multimedia delivery networks,delivers streaming effectively,and has a good adaptability.At last,we verify our strategy with considered designed experience.our proposed algorithm can effectively deliver multimedia to the destination nodes through the ＂middle mile＂ of Multimedia delivery networks.
