降低播放时间的初始延迟、播放过程中的延迟抖动和网络带宽利用率对多媒体流媒体业务至关重要。为了实现这两个目标，我们的点对点多媒体缓存服务利用了客户端集合的接近性以及客户端上缓存流的时间和空间局部性。完全连接在一起的对等客户端不仅从服务器接收多媒体流，而且根据请求将缓存的流发送给对等客户端（如代理服务器）。所有关于对等客户端及其缓存的视频片段、连接质量的信息都由缓存服务通过发布/订阅协议进行维护。本文给出了在点对点客户端协作环境中实现多媒体流、流调度、预取和切换流客户端的方法。我们的模拟结果表明，在播放时间提供小的初始延迟和低抖动。
Reducing initial delay of playing time, delay jitter during playing time, and network bandwidth utilization is important for multimedia streaming service. In order to achieve these two goals, our peer-to-peer multimedia caching service exploits the proximity of set of clients and temporal and spatial locality of cached streams on the clients. Peer clients, which are fully connected together, not only receive multimedia streams from a server, but also send cached streams to peer clients like a proxy server upon its request. All information about the peer clients, and video segment they cache, quality of connections, are maintained by a cache service via the publish/subscribe protocols. This paper shows approaches for multimedia streaming, streaming scheduling, pre-fetching and switching streaming clients in the collaborative environment of peer-to-peer clients. Our simulation results show provisioning small initial delay and low jitter during playing time.
