P2P网络中的激励机制分析

Analysis of Incentive Mechanisms in P2P Network

将P2P网络中的激励模型引入到流媒体点播系统的设计中,促使节点提高对系统的贡献,从而在节点之间建立一种公平的互相交易的环境。本文对P2P网络中基于微支付的模型、基于互惠的模型、基于信誉的模型进行阐述。在响应优先级、带宽占用率以及服务质量等方面,通过区分服务策略引起基于P2P的IPTV环境下终端节点间的竞争,从而提高IPTV效率。

This paper uses the incentive model to design the streaming media video on demand system, which is used in the P2P network. In this way, the contribution of every point for the whole system network is improved, and therefore all the points can build a fair transaction environment. This paper elaborates some models of P2P network, such as the model based on micropayment, the model based on reciprocity, and the model based on credit. This paper uses the way of differentiated services strategy to make all the points compete in the aspects of response priority, the bandwidth usage and the quality of service. Therefore the efficiency of IPTV system is improved.
