| 摘 要： | 与传统的PSTN不同,IP网络主要为用户提供基于服务器/客户端的非对称的数据业务.由于IP网络服务的无地域性和无国界性,在用户数量达到一定程度时,用户对信息的消费会给包含有受用户欢迎的信息内容的服务器造成巨大的压力,同时造成接近于这些服务器的骨干网络的拥塞.最近几年内作为解决这些问题的内容分发技术成为业界的研究热点之一,本文主要介绍目前IP网络上较多采用的CDN(content distribution network,内容分发网络)技术、组播技术和端到端技术等几种IP网络内容分发技术.

| Abstract: | It is different to the PSTN, that IP based network mainly providers users client/server based unsymmetry data services. When the number of the users becomes very huge , it is difficult for the servers which contain user favor information to make responses to a vast number of users requests. And they also make the backbone network to which the favor servers connect with congestion. The method to solve these problems is to use content distribution technologies. This article mainly introduces several kinds of content distribution technology used on IP based networks currently, such as CDN, peer to peer and multicasting. |
