P2P网络是否具有超级可扩展性?

Can P2P Networks be Super-Scalable?

François Baccelli, Fabien Mathieu, Ilkka Norros, Rémi Varloot

摘要:

我们提出了一个新的对等网络模型,它考虑到网络瓶颈以外的访问。该模型可以处理P2P网络的关键特征,如程度或位置约束,以及远距离对等体的速率通常小于附近对等体的事实。使用基于速率函数的网络模型,我们给出了一个封闭的形式表示在系统的流体限制,以及近似的其他情况下的节点下载性能。我们的研究结果表明,存在现实的设置,平均下载时间是一个递减函数的负载,我们称之为超可扩展性的现象。

英文摘要:

We propose a new model for peer-to-peer networking which takes the network bottlenecks into account beyond the access. This model can cope with key features of P2P networking like degree or locality constraints together with the fact that distant peers often have a smaller rate than nearby peers. Using a network model based on rate functions, we give a closed form expression of peers download performance in the system's fluid limit, as well as approximations for the other cases. Our results show the existence of realistic settings for which the average download time is a decreasing function of the load, a phenomenon that we call super-scalability.
