我们提出了一种新的低成本的视频点播架构的异构对等网络。该架构的核心思想是聚合节点的存储和带宽，以促进按需视频流。为了实现这一目标，我们将已发布的视频分成片段并将其分发给不同的同行。当观看视频时，对等体搜索相应的片段，然后聚合来自多个提供对等体的带宽以流式传输视频。这种架构不依赖于强大的服务器/代理，而是利用经常未充分利用的对等体的资源，这使得它具有成本效益。我们证明了这种架构的有效性，通过广泛的模拟实验大型，类似互联网的拓扑结构。
We propose a novel low-cost video-on-demand architecture for heterogeneous peer-to-peer networks. The key idea of this architecture is to aggregate peers' storage and bandwidths to facilitate on-demand video streaming. To achieve this goal, we split published videos into segments and distribute them to different peers. When watching a video, a peer searches the corresponding segments, and then aggregates bandwidths from multiple supplying peers to stream the video. Instead of relying on the powerful servers/proxies, this architecture exploits the often-underutilized peers' resources, which makes it cost-effective. We demonstrate the effectiveness of this proposed architecture through extensive simulation experiments on large, Internet-like topologies.
