基于DPI的内容缓存技术及应用

随着3G时代的来临,越来越多的用户通过手机、上网卡访问互联网。为提升3G用户上网体验,本文提出基于DPI(DeepPacketInspection,深度数据包检测)的内容缓存技术,对该技术的技术原理、系统架构、系统的部署方式进行了研究。应用该技术,通过在城域网上建立缓存节点,可有效缓解城域网出口带宽压力,节省网间结算,提升用户上网体验。

Technology and Application of Content Cache Based on DPI

With the 3G era＇s coming, more and more users access internet via mobile phone and wireless network card. In order to promote users＇ experience, the technology of content cache based on DPI （Deep Packet Inspection） was applied to the network. The principle, the architecture and the deploying method of the system were researched. tt efficiently reduced bandwidth pressure of the networks on the export of the MAN by setting caching nodes, and it reduced the expense of inter-network.
