命名数据网络体系架构的应用与发展

Application and Development of Named Data Network Architecture

命名数据网络(Named Data Networking,NDN)是一种以信息为中心的新型网络架构,因采用了独特的内容命名法、缓存机制和智能转发策略而受到广泛关注。首先介绍了NDN的基本原理、关键技术以及研究现状,并与TCP/IP架构对比分析了其性能优势;然后总结了NDN在车载自组织网(Vehicular Ad Hoc Network,VANET)、远程视频会议系统、大数据处理分析中的典型应用及研究现状;最后围绕实际应用指出了该技术的不足,并分析预测了其未来应用趋势。NDN对于解决互联网设计中日益凸显的安全性、移动性、可扩展性等方面的问题具有显著优势。

Named data networking(NDN) is a new information centric networking(ICN) architecture,which has attracted wide attention due to its unique content naming,caching mechanism and intelligent forwarding strategy. Firstly,the basic principle,key technologies and research status of NDN are introduced,and the performance advantages are analyzed and compared with TCP/IP architecture. Secondly,typical applications and research status of NDN in vehicular ad-hoc network(VANET),remote video conference system and processing and analysis of big data are summarized. Finally,the limitation of this technology is pointed out around the practical application and its development prospect is analyzed. NDN has significant advantages in solving the increasingly emerging problems of security,mobility and scalability in Internet design.
