    Survey of Naming and Addressing Architecture Based on Locator/Identifier Split

    • 摘要: 随着互联网的发展,传统TCP/IP网络体系结构的IP地址语义过载问题所导致的移动性、扩展性和安全性等方面的缺陷逐渐暴露出来,并限制了多宿主、流量工程等新技术的发展.针对这一问题,学术界普遍认为需要对下一代互联网的命名和寻址体系结构进行重新设计,将位置与标识分离作为新一代互联网的基本设计原则之一.近年来,涌现了许多基于位置与标识分离的新技术和解决方案.首先对基于位置与标识分离的网络体系结构研究所面临的关键性问题进行了分析;然后对相关研究工作进行了回顾,并对相关代表性研究成果进行了深入评述;最后展望了未来的一些研究方向.

       

      Abstract: With the development of the Internet, some drawbacks of the original TCP/IP architecture on mobility, scalability and security have been exposed gradually. One of the most important reasons is the problem of semantic overloading of IP address. Current IP address has dual semantic functions, which indicates both the network node’s routing locator and its endpoint identifier. The “IP overload” also limits the development of several new technologies including multi-homing, traffic engineering, etc. To tackle this problem, many researchers believe that it is necessary to build a clean-slate design of the naming and addressing architecture for the future Internet. The reason of the above drawbacks lies in the fact that there is no accurate, unique and permanent identifier to describe a network node. IAB (Internet Architecture Board) announced that in order to resolve the “IP overload”, two name spaces should be introduced to denote a network node’s locator and identifier separately, which is called “locator/identifier split”. In recent years, many new techniques and approaches have emerged based on this principle. The authors analyze some challenging problems in the research of network architecture based on “locator/identifier split”, and give a review of related works. Comments on some representative research proposals are also presented. Finally, some future research directions and further discussion are listed.
