基于网络编码的P2P流媒体系统设计
首发时间:2011-03-10
摘要:P2P流媒体直播系统中由于参与用户的不确定性,造成系统的不稳定,用户的随意加入退出,给维持网络均衡,造成不同用户的播放质量得不到保证。而网络编码的提出,对解决这一问题提供了新的思路。本文在引入网络编码的同时,使用分层流媒体的概念,设计一种适合的系统,让播放质量能够随带宽的影响而变化,增强整个系统的鲁棒性,减小P2P网络状态变化对系统的影响。

The Design of P2P Streaming Media System Based on Network Coding
Abstract:The uncertainty of user participation in P2P live streaming system, result in system instability, the users join or exit from network randomly, making the network unbalanced, causing the QoS of different users can not be guaranteed. The network coding's proposed, provides a new way of thinking to solve this problem. In this paper, the introduction of network coding, while the concept of using a layeredstreaming media, design a suitable system to allow the QoS follow with the changing of bandwidth, and enhance the robustness of the system, reducing the P2P network state changing impact on the system.
Keywords: P2P network coding streaming media
