摘　　要：近年来随着各种互联网应用爆发式发展,特别是在线视频业务的快速增长,对IP城域网带宽带来越来越大的压力,传统的带宽扩容建设模式难以为继。Cache是一种用存储换带宽的技术,通过将应用内容引入至城域范围内,从而减少电路扩容规模。通过对目前业内主流的IP城域网HTTP Cache技术进行分析研究,根据各类缓存技术的应用场景并结合IP城域网的相关特点,提出IP城域网HTTP Cache技术部署策略和容量计算方法供网络建设和规划参考。Recently various Internet applications develop quickly,especially the increasing of online video service,bring more and more pressures to IP MAN. The traditional construction mode for business development is difficult to continue. Cache is a technology which uses storage to exchange bandwidth,cut the construction investment through taking net applications into metropolitan area. It discusses the HTTP cache technology in IP MAN. Based on the application scenarios of different cache technology and the features of IP MAN,it provides the deployment policy of HTTP cache technology and computing method of capacity for network development and programming.
