LISP-HIMS:一种基于LISP的层次化标识映射系统

摘要

Aiming at the problem of currently rapid growth of global routing table size in DFZ, IETF has proposed to reconsider the Internet addressing architecture by splitting host identifier and its routing locator. LISP is considered to be one of the most promising solutions based on such idea, which was proposed by Cisco. This paper presented a novel mapping system for LISP proposal, elaborated the model and modes of this mapping system and also the allocation strategy of the hierarchical host identifier. Compared with other LISP-based mapping systems, the proposed mapping system has better scalability and lower mapping querying latency.%针对目前全球路由表规模高速增长的问题,IETF提出可以通过分离主机的身份标识和路由标识地址空间来重新考量互联网寻址体系结构.思科公司提出的LISP(Locator Identity Separation Protocol)是基于该思想提出的主流方案之一.首先提出一种新的基于LISP的层次化标识映射系统,以克服目前其他LISP映射系统的不足,然后详细阐述该系统的模型、工作模式以及主机身份标识的分配方案；最后与其他LISP映射系统进行了分析与比较,结果表明,该系统具有良好的可扩展性以及更低的映射信息查询时廷.
