具有网络感知能力的P2P系统研究

Research on P2P system with network awareness

文章主要研究了P2P网络的应用及对现有IP网络带来的影响以及解决办法。文章首先分析了网络运营商为了应对P2P的影响采取的手段并分析了其发展趋势,指出这些方案不能很好地兼顾P2P流量优化和P2P应用的QoS问题。针对P2P应用假设运营愿意提供网络拓扑信息以及P2P应用服务所造成的QoS问题,文章提出了一种具有网络感知能力的P2P系统。

The paper mainly studies the application of P2P network and influence on existing IP network and solutions. First, this paper analyzes countermeasures adopted by the network operators in order to deal with the influence from P2P and the development trend is analyzed, and points that these schemes can not take into account the P2P traffic optimization and QoS problem of P2P application. Assuming that QoS is willing to provide network topology information and P2P application services for P2P applications, a P2P system with network awareness is proposed in this paper.
