P2P实时流媒体系统服务器部署

摘要

P2P服务器部署作为解决P2P系统跨网络流量等问题的一种有效方案引起了业界的关注.由于peer的资源贡献能力,传统服务器部署模型不能在P2P系统中获得预期效果.本文通过简单示例来揭露P2P需要服务器部署.在此基础上提出一种新的P2P流媒体应有的服务器部署模型.该模型综合考虑了部署成本、服务性能和peer贡献能力等因素,能满足不同P2P流媒体提供商的需求.理论分析结果表明该部署模型具有很好的网络适应能力,适合P2P系统应用.%P2P server placement has attracted the interesting of some researchers as an effective solution to the problems brought by P2P, such as cross traffic among different networks. However,due to the unique features of P2P systems, the traditional placement models cannot yield the desirable service performance. So, we first demonstrate that P2P need server placement strategy by a simple example, and then propose a suitable server placement model for P2P live streaming systems. This model takes the deployment cost, users'experience and peer contribution into account and can satisfy interests of different P2P providers. The theoretical analysis shows that this model is more suitable for P2P systems than the traditional placement models.
