物联网由大量的终端设备组成,它对标识终端的IP地址需求非常大。该文介绍了物联网的概念、现有体系结构和采用的关键技术,阐述了IPv6的特性和优势,总结了IPv6技术不仅能够满足物联网的地址需求,还能够满足物联网对节点移动性、基于流的服务质量保障的需求。 The Internet of Things consists of a large number of terminal devices, which have a very large demand for the IP address of the identity terminal. This paper introduces the concept of the Internet of things, the existing architecture and the key technologies used, expounds the characteristics and advantages of IPv6, concludes that IPv6 technology can not only meet the needs of the Internet of things addresses, but also to meet the IOT for node mobility, Stream-based service quality assurance needs.
