我们考虑设计一个开放的P2P视频直播系统。当设计一个开放和P2P的实时视频系统时，系统必须包括激励对等点贡献上传容量的机制。我们提倡一个激励原则的P2P直播：peerpsilas视频质量是相称的上传速率。我们提出了子流交易，一个新的P2P流设计，不仅使差异化的视频质量相称的peerpsilas上传贡献，但也可以容纳不同的视频编码方案，包括单层编码，分层编码，和多描述编码。大量的跟踪驱动的模拟表明，子流交易具有高效率，提供差异化的服务，低启动延迟，具有不同的互联网接入速率的同行之间的协同作用，并防止搭便车。
We consider the design of an open P2P live-video streaming system. When designing a live video system that is both open and P2P, the system must include mechanisms that incentivize peers to contribute upload capacity. We advocate an incentive principle for live P2P streaming: a peerpsilas video quality is commensurate with its upload rate. We propose substream trading, a new P2P streaming design which not only enables differentiated video quality commensurate with a peerpsilas upload contribution but can also accommodate different video coding schemes, including single-layer coding, layered coding, and multiple description coding. Extensive trace-driven simulations show that substream trading has high efficiency, provides differentiated service, low start-up latency, synergies among peers with different Internet access rates, and protection against free-riders.
