The current Internet is facing serious scalability problems and the over- loading of Internet Protocol (IP) addresses is regarded as an important reason. The Locator/ID Separation Protocol (LISP) is proposed as a network-based so- lution that separates IP addresses into Routing Locators (RLOCs) and Endpoint Identiers (EIDs) to address the routing scalability problems. It is a critical chal- lenge for LISP to design a scalable and ecient mapping system. In this paper, we propose a hierarchical mapping system (HMS). HMS consists of two levels with the bottom level maintaining the EID-to-RLOC mappings in an Autonomous System (AS) and the upper level storing the mappings between EID-prexes and ASs in the global network. We adopt one-hop Distributed Hash Table (DHT) to organize
