VoD中基于前缀的流行视频流链接方案
Prefix based Chaining Scheme for Streaming Popular Videos using Proxy servers in VoD
摘要：
流传输高质量视频会消耗大量的网络资源。在这种情况下，请求服务延迟，网络流量，拥塞和服务器过载是要考虑的主要参数，在视频流通过互联网的服务质量（QoS）的影响。在本文中，我们提出了一个有效的架构作为一个集群的代理服务器和客户端，使用对等（P2P）的方法来合作流的视频使用链接技术。我们考虑以下两个关键问题，在建议的架构（1）前缀缓存技术，以容纳更多的视频接近客户端（2）合作客户端和代理链接，以实现网络效率。我们的模拟结果表明，所提出的方法产生一个前缀缓存接近最佳的解决方案，最大限度地减少广域网带宽使用的服务器-代理路径上，通过利用代理-客户端和客户端-客户端的路径带宽，这是比昂贵的服务器代理路径带宽，服务器负载，客户端拒绝率显着使用链接便宜得多。
英文摘要：
Streaming high quality videos consumes significantly large amount of network resources. In this context request to service delay, network traffic, congestion and server overloading are the main parameters to be considered in video streaming over the internet that effect the quality of service (QoS). In this paper, we propose an efficient architecture as a cluster of proxy servers and clients that uses a peer to peer (P2P) approach to cooperatively stream the video using chaining technique. We consider the following two key issues in the proposed architecture (1) Prefix caching technique to accommodate more number of videos close to client (2) Cooperative client and proxy chaining to achieve the network efficiency. Our simulation results shows that the proposed approach yields a prefix caching close to the optimal solution minimizing WAN bandwidth usage on server-proxy path by utilizing the proxy-client and client-client path bandwidth, which is much cheaper than the expensive server proxy path bandwidth, server load, and client rejection ratio significantly using chaining.
