| 摘 要： | CDN-ON-P2P网络中P2P节点的兴趣表现在其对内容资源的需求上,本文分析了基于兴趣划分的P2P内容发布网络的基本结构,研究了基于兴趣划分的子网上内容分发算法的基本形式,并研究给出了一种根据用户节点网络状态选择成为伪CDN节点的算法,在该算法中引入兴趣权的概念,用于表达节点之间资源的相似性。该算法根据设定条件选择用户节点作为内容发布节点,可以在一定程度上减少网络中代理服务器的数量,提高网络的可靠性,降低网络流量。

| Abstract: | The interest of peer in CDN-on-P2P shows the requirement of resources. This paper analyses the structure of CDN-on-P2P based on interest subnet grouping,and studies the basic type of content delivery algorithms for subnet grouping. An algorithm that selects a user peer as the CDN peer according to its status is proposed. Interest-weight is used to show the correlation of the user peer resources. In this algorithm,a user peer is selected as the CDN peer based on setting conditions.The experimental results sh... |
