| 摘 要： | 随着网络技术的高速发展,Internet用户飞速增长,网络拥塞、服务器负载过重、访问延迟过大等问题一直困扰着用户。CDN(ContentDistributionNetwork———内容分发网络)的出现极大改善了Internet的访问速度和服务质量。但是,流媒体内容的日益流行又对CDN技术提出了新的挑战。文章详细阐述了在CDN条件下,基于代理缓存机制,对流媒体进行智能分发技术的研究现状,详细描述了流媒体在主干网中的分发传输和它们之间的协作过程。

| Abstract: | With the high development of network technology,the consumers of Internet becomes more and more,it brings on some problems ,such as network congestion,overweight load of the server,the great delay for network access-ing.The emergence of CDN(Content Distribution Network)conduces maximum improvement over accessing speed and service quality of Internet.Whereas,the popularity of streaming media brings challenges the technology of CDN.This pa-per bats around the study actuality of intellective distribution technology for streaming medias under the term of CDN and the proxy caching mechanism,it also depicts the distribution transmission of streaming medias in the backbone net-work and the collaboration procedure among them,etc. |
