摘要
信息中心网络(Information-Centric Networking,ICN)已经成为下一代网络体系结构研究的新热点.从众多研究成果中及时地总结ICN的优势与不足是未来相关研究的重要基石.尽管现有ICN综述文献已经对其体系结构做出较为详细的总结,然而,它们并没有充分地讨论TCP/IP网络体系结构中存在的问题与发展ICN必要性之间的关系,而这影响到未来ICN的重点研究方向.文中首先论述了应用ICN体系结构解决当前网络体系结构中已有问题的必要性,将ICN的关键问题、结构构成、关键技术等进行了梳理,从现有ICN方案中整理出信息命名、路由技术、试验平台等关键技术.在这个基础上,文中进一步讨论分析了ICN与现有的协同缓存系统等技术之间的关联与差异.论文最后分析讨论了ICN的下一步发展方向以及有待研究的问题.
Information-Centric Networking（ICN）has been a novel hotspot in the field of future Internet architecture.In the future,the foundation of correlational research is to find out the strengths and weaknesses of ICN from many study results in time.The existing literatures of ICN have made the detailed summary about its architecture.Meanwhile,the relationship between the existing problems of TCP/IP network architecture and the necessity of developing ICN hasn＇t been discussed completely.This paper discusses the necessity of using ICN to solve the current network problems firstly,and sorts out the key points of ICN,its structure,key technologies and so on.Through the existing programs of ICN,the key technologies of naming,routing and testbed have been finished.On this basis,this paper has further discussion on the relevance and difference among ICN,cooperative caching system and some other technologies.At last,it analyses and discusses the next developing direction of ICN and some problems to be studied in the future.
