关于在P2P直播中使用种子

On Using Seeders for P2P Live Streaming

Fabien Mathieu

摘要:

种子节点(不请求任何东西但对系统有贡献的节点)是对等网络(P2P)中的一个强大概念。它们允许利用P2P系统的能力。虽然播种对于文件共享或视频点播应用程序来说是一个自然的想法,但在实时流媒体的背景下,它似乎有些违反直觉。本文旨在描述P2P直播的可行性和性能。在正式定义了“直播”和效率之后,我们考虑了忽略开销的系统的理论性能。然后,我们提出了一个线性开销模型,并扩展了该模型的结果,为一个单一的播种机和一组播种机以及(它并不总是可以完美地聚合在一个给定的系统中的个人效率)。

英文摘要:

Seeders (peers that do not request anything but contribute to the system) are a powerful concept in peer-to-peer (P2P). They allow to leverage the capacities of a P2P system. While seeding is a natural idea for filesharing or video-on-demand applications, it seems somehow counter-intuitive in the context of live streaming. This paper aims at describing the feasibility and performance of P2P live seeding. After a formal definition of "live seeding" and efficiency, we consider the theoretical performance of systems where the overhead is neglected. We then propose a linear overhead model and extend the results for this model, for a single seeder and for a set of seeders as well (it is not always possible to perfectly aggregate individual efficiencies in a given system).
