现在P2P技术已经成为非常热门的研究方向,也出现了很多与之相关的实际项目,有力的推进了P2P技术的应用。P2P同C/S的工作模式有很大的不同,它改变了C/S模式中服务器端和客户端分离的概念,把它们重新结合起来。现在的很多VOD视频点播系统,其内容更新仍然需要内容管理员定期进行手工更新,所以我们提出了采用P2P技术对VOD系统节目资源进行自动更新的方式。
Now P2P technology has become a very hot research direction, but also appeared a lot of related practical projects, effectively promote the application of P2P technology. P2P is very different from C / S working mode, it changed the concept of server-side and client-side separation in C / S mode and combined them again. Nowadays, many VOD video-on-demand systems still require content administrators to update their content regularly by hand. Therefore, we propose a way to automatically update the VOD system program resources by using P2P technology.
