摘要

内容分发网络是一种以降低互联网访问时延为目的

在网络边缘或核心交换区域部署内容代理服务

通过全局负载调度机制进行内容分发的新型覆盖网络体系.随着多媒体网络流及实时交互技术的兴起

现今内容分发网络已成为互联网的核心应用之一.本文介绍了内容分发网络的演变过程与体系结构

深入剖析了内容分发网络的核心功能组件与工作机制

对当前主流内容分发网络进行分类

并讨论了内容分发网络性能度量

最后探讨了内容分发网络的未来挑战与进一步研究方向.

Abstract

CDN (Content Delivery Network) is a novel overlay network

which deploys surrogates on the edge or backbone of network in order to reduce the access delay;it improves the efficiency of content delivery on the global load balance component.In current status

CDN has been a core Internet application as the development of multimedia and network technologies.In this paper

the evolution of CDN and its architecture are introduced;the key component of CDN and mechanism are presented;the taxonomy of CDNs and the performance measured strategies are reviewed.The developing trends of CDN and further topics in this area are also analyzed.
