Name data networking (NDN) is one of the proposed ICN based future Internet architecture aims to substitute our current TCP/IP based Internet. The recent advancements in technology reduced the cost to connect to the Internet and made it feasible to connect a wide variety of devices that leads to rapid growth in hand-held devices and exponentially increased Internet users. The Internet usage pattern has also changed dramatically in the last decade and a considerable proportion of Internet traffic consists of video files only. TCP/IP based Internet was designed to communicate between point to point entities and mobility, multicast support, security, and a tremendous amount of Internet traffic was not considered at that time. The mismatch between Internet usage requirements and current Internet architecture motivated researchers to come up with content based new sustainable Internet architecture. NDN is designed from a clean slate and supposed to overcome the shortcomings while leverage strength present in TCP/IP based Internet architecture. NDN is a request-driven architecture where users request for content using names without concern about host. This article presents a detailed survey on NDN architecture, protocols, and previously proposed strategies. It also offers a comparative study on proposed strategies for naming, content caching, inter and intradomain routing, forwarding, and security. This survey uses a bottom-up approach and a new taxonomy for comparative analysis and assessment to present insights about the differences between the existing strategies and protocols proposed for NDN. The survey also explored the present applications and ongoing research and suggests future research directions.

名称数据网络（NDN）是提议的基于ICN的未来Internet体系结构之一，旨在替代我们当前基于TCP / IP的Internet。技术上的最新进展降低了连接到Internet的成本，并使连接各种设备变得可行，这导致了手持设备的快速增长，并且互联网用户呈指数增长。在过去的十年中，Internet的使用方式也发生了巨大变化，并且很大一部分Internet流量仅包含视频文件。基于TCP / IP的Internet旨在在点对点实体之间进行通信，并且具有移动性，多播支持，安全性，并且当时还没有考虑大量Internet流量。Internet使用要求和当前Internet体系结构之间的不匹配促使研究人员提出了基于内容的新型可持续Internet体系结构。NDN是从一开始就设计的，旨在克服缺点，同时利用基于TCP / IP的Internet体系结构中存在的优势。NDN是一种请求驱动的体系结构，用户可以使用名称来请求内容，而不必担心主机。本文介绍了有关NDN体系结构，协议和先前提出的策略的详细调查。它还对命名策略，内容缓存，域间和域内路由，转发和安全性的提议策略进行了比较研究。这项调查使用自下而上的方法和新的分类法进行比较分析和评估，以提供有关针对NDN提出的现有策略和协议之间差异的见解。该调查还探讨了当前的应用和正在进行的研究，并提出了未来的研究方向。
