    • A Peer-to-Peer protocol such as BitTorrent is used to assist streaming. Peers download streaming content from the P2P network while simultaneously playing the downloaded content. As the stream plays, an end system downloads any missing pieces directly from a server or other infrastructure node. This method roughly squares server capacity and can be refined to require on average 0(1) servers regardless of the number of concurrent users. Thus BitTorrent assisted streaming scales better than traditional server-client and other infrastructure-only solutions, each of which requires a number of infrastructure nodes that scale linearly as a function of the number of users. Unlike End-System-Multicast, BitTorrent assisted streaming does not subject users to the vagaries of intermediate unreliable, potentially bandwidth-constrained end-systems; the departure of any single end-system has minimal impact on overall performance; and BitTorrent has a well-crafted incentive mechanism for encouraging users to contribute their upstream capacity.
    • 使用诸如BitTorrent之类的对等协议来协助流媒体。 对等人同时播放下载的内容,从P2P网络下载流媒体内容。 随着流的播放,终端系统直接从服务器或其他基础设施节点下载任何丢失的部分。 这种方法大致平方的服务器容量,可以细化,要求平均0(1)服务器,不管并发用户的数量。 因此,BitTorrent协助流式传输比传统的服务器 - 客户端和其他基础设施解决方案更好,每个解决方案都需要大量基于用户数量的基础设施节点。 与终端系统组播不同,BitTorrent辅助流媒体不会使用户受到中间不可靠,潜在带宽受限的终端系统的变幻莫测; 任何单一终端系统的离开对整体性能影响最小; BitTorrent有一个精心设计的激励机制,鼓励用户贡献自己的上游能力。
