摘要

BitTorrent目前是可扩展内容分发的事实上的标准。然而，它的点对点资源分配模型不能提供高可用性，其性能依赖于对等体的最大努力贡献。这促使一些内容提供商使用一种混合模式，在这种模式中，他们运营一个超级对等体，以获得更高的服务质量。在本文中，我们使用BitTorrent跟踪和分析模型来调查这样一个实体所产生的成本与它可以为系统提供的利益之间的关系。

On the Efficiency and Cost of Introducing QoS in BitTorrent

BitTorrent is currently a de facto standard for scalable content-distribution. However, its peer-to-peer model for resource allocation does not provide high availability and its performance depends on best-effort contributions given by peers. This has motivated several content-providers to use a hybrid model in which they operate a superpeer in order to attain a higher quality of service. In this paper, we use BitTorrent traces and analytical modelling to investigate the cost incurred by such an entity in relation to the benefits it can provide to the system.
