信息中心网络体系结构研究综述

Survey of Research on Information-Centric Networking Architecture

互联网应用需求逐渐转变为信息的分发和获取,而网络体系结构依然为主机间的端到端通信,二者矛盾日趋尖锐.信息中心网络(Information-Centric Networking,ICN)采用以信息为中心的设计为解决上述问题提供了新思路.本文提出了ICN的基本体系结构框架,从功能和特性两个维度探索了ICN可能的设计空间,然后讨论了ICN与其他未来网络技术的关系以及ICN实验平台和部署,最后指出当前主要问题及下一步研究方向.

The application model in the Internet has shifted into information sharing,while the architecture is still based on the end-to-end communication.The conflict between them is becoming increasingly acute.To solve such a mis-match,ICN （Information-Centric Networking）is proposed.In this paper,a basic architecture framework for ICNs is first proposed,functional modules and properties are adopted to explore the design of ICN.Then,the relationships between ICN and other future network technologies are analyzed,the experiment platform and the deployment of ICN are discussed.Final-ly,crucial issues and future researches are concluded.
