摘　　要：信息中心网络ICN作为新兴的网络架构是当前的研究热点之一。在采用寻址和路由分离的ICN架构中,名字解析系统作为核心基础设施提供了管理和维护内容标识符与定位符之间映射关系的功能。名字解析系统通常分布式地部署为用户提供服务,分布在网络中的名字解析节点及相互间建立的关系共同构成系统的结构,系统的结构与系统中数据的存储和路由、节点管理等都密切相关,直接影响着系统为用户提供服务的功能和性能。本文对ICN中名字解析系统的结构进行调研,总结了不同类型系统结构的特征和原理,并进行了对比分析,为ICN中名字解析系统后续的研究提供了参考。Information-Centric Networking(ICN)has become a hot spot topic for research as an emerging network architecture.In the ICN architectures that use the addressing/routing separation mode,a name resolution system(NRS)provides the function of managing and maintaining the mapping between content identifiers and locators as the core infrastructure.A NRS is usually deployed in a distributed form and provides service to users.The relationship between name resolution nodes distributed in the network constitutes the structure of the system.The system structure is closely related to data storage,routing and node management,which directly affects the system’s ability to provide services to users and performance.In this paper,the structure of ICN name resolution system is investigated,the characteristics and principles of different types of system structures are summarized,and their advantages and disadvantages are compared and analyzed,which provides reference for the subsequent study of NRS in ICN.
