摘要:

本文充分利用P2P技术具有多客户机资源的优势,克服其具有不稳定性和波动性的不足;针对直播业务,提出两种P2P结构模型,在发行商、运营商和用户之间构架可靠的P2P模型;提出了一种新的激励机制,有效解决了用户的扩展问题、用户的服务质量问题以及发行商的利益问题等。分析表明,这种激励机制可以保证系统的可靠性,并且可以避免由于节点频繁加入和退出引起的波动,保障了用户的服务质量。

Abstract:

The paper fully utilizes the P2P advantage of featuring multiple-client resources,overcomes its demerits of instability and fluctuation,and proposes t wo P2P structural model to construct reliable P2P models between the issuer, operator and users. We also present a new incentive mechanism to solve the users' expansion problem, QoS problem and the issuer's benefit problem and the issuer's benefit problem effectively. Analysis shows that this mechani ism can guarantee the reliability of the system, avoid the flustuation and protect the users' QoS.
