摘要: 云服务传递网络(Cloud Scrviccs Dclivcry Nctworks,CSDN)在Intcrnct之上构建了一层分布式服务器网络,以就近和按需的方式向用户提供云传递服务。互联网流量的非线性快速增长及其表现出的视频化、移动化和交互化等特点,使得以提供高效、可信云传递服务为目标的CSDN面临诸多新挑战。首先在介绍和分析CSDN背景与新挑战的基础上,从基础设施层、平台层和服务层等3个维度提出了一个现有相关技术的分类模型。然后全面综述了CSDN相关技术的最新研究现状,包括节点内组网、服务器部署、内容命名、内容管理、请求解析和系统管理等。最后指出了CSDN的未来研究趋势,即CSDN }需突破的新技术问题,包括协同、移动管理和交互支持等。

Abstract: Cloud Services Delivery Networks(CSDN) build a layer distributed server network on top of Internet and provide users with cloud delivery services using the way to the nearest and on-demand. With no-liner and rapid growth of Internet traffic and three characteristics referring to the Internet traffic including a large scale video traffic, mobile traffic and interactive traffic presented by itself, in order to provide efficient and reliable cloud delivery services,CSDN faces many new challenges. hhis paper first described and analyzed the background and new challenges of CSDN, on the basis presented a classification model of the existing technologies from three dimensions infrastructure layer, platform layer and service layer et al. And then a comprehensive overview of the latest technologies of CSDN research was given,including networking inside CSDN nodes, server placement, content naming, content management, request parsing and system management. Finally, future research trend of CSDN was pointed out, that is the new technology issues what CSDN much-needed breakthrough, including cooperation, mobility management and interactive support al et.
