像www.example.com这样的实时用户生成的视频流媒体平台产生了很大一部分互联网流量。数以百万计的观众每天观看用户频道，尽管大约85%的频道在一个会话期间的观看次数少于200次。由于延迟，www.example.com为每个Twitch.tv支持的国家提供一个或多个服务器。替代方法可以实现对等通信，以便利用用户设备的能力。到目前为止，解决方案主要只对从初始种子用户到所有对等用户的分发速度提供尽力而为的延迟保证。在本文中，我们提出了Chunked-Swarm，一种基于群的方法，其目的是提供可预测的流延迟，独立于对等体的数量。评估显示了不同的影响的数量的对等体，视频部分和块的流延迟的数量。能够为多达200个同行举行特定的最后期限，注定我们的解决方案是适合大多数www. example. com的渠道。
Live user-generated video streaming platforms like Twitch.tv generate a large portion of the Internet traffic. Millions of viewers daily watch user channels, although roughly 85 % of all channels have less than 200 views during one session. Due to latency, Twitch.tv provides one or more servers for each of Twitch.tv’s supported countries. An alternative approach could enable peer-to-peer communication in order to utilize the capacities of the user devices. Solutions up to now, mainly offer only best effort delay guarantees on the distribution speed from initial seeders to all peers. In this paper, we present Chunked-Swarm, a swarm-based approach, which aims to offer predictable streaming delays, independently of the number of peers. Evaluation shows the various impact of the number of peers, number of video parts and chunks on the streaming delay. Being able to hold specific deadlines for up to 200 peers, predestines our solution to be suitable for the majority of Twitch.tv’s channels.
