一种P2P流媒体资源的索引与传输机制

A Kind of Indexing and Transmission Mechanism for Streaming Media

在P2P流媒体系统中,一个高效实用的资源索引及传输机制能很好地均衡系统的负载,加强系统的稳定性,并减少节点的搜索时延。在实际的应用中,不同服务能力的节点对于整个网络的不同贡献应该得到不同的激励。本文提出一种具有商业激励的P2P流媒体系统资源索引及传输机制。文章在对节点进行空间划分的基础上,对现有的节点良好度评价标准,节点排序算法做出了改进,并在相应的商业激励值下进行数据的传输。该机制加快了资源的搜索速度,均衡了系统负载并提高了用户上传的积极性,对于现有P2P流媒体系统的改进具有积极的意义。

In the P2P media system, an efficiency and practicality mechanism to get and transmit data can balance the load of the system, strengthen system s stability and decrease the time delay of searching the peers. In the real application, different service ability of peers will have dissimilar contribution, so they should get different benefit. In this passage, we bring forward a mechanism with business encouragement for P2P media system s data getting and transmitting. This passage on the foundation of a kind o...
