摘　　要：随着宽带网络的建设,IP视频应用的逐步普及,现有的基于集中控制/传输模式的服务器将成为系统的瓶颈。本文分析了传统视频数据传输方式的不足,提出了利用Linux的Iptables建立分布式服务器集群模式,及采用渐进传输和动态缓冲区等技术改进视频数据传输的具体方案。从改进服务器体系结构和视频数据传输两方面入手,解决IP视频服务器的瓶颈问题。Along with the rapid construction of broad band network, the application of IP video become gradually popular. The structure based concentrate control and transfer will become bottleneck of a system. This letter analyzes the shortage of tradition video transfer, presents a solution of server cluster based on Linux via Iptables, improves video data transfer method via gradually transfer and dynamic buffer. The solution this paper arises, start with two aspects, which are improving server structure and data transfer method, to solve the bottleneck problems exist in IP video application.
