A Hierarchical Mapping System Approach for ID-to-Locator Resolution

Internet Default Free Zone (DFZ) is facing today a serious scalability problem due to the double use of the current Internet Protocol (IP) name space. IP name space today is used both for location and identification of a host. To solve this problem, Identifier and Locator separation approach was proposed and implemented in many schemes. However, the big challenge in the separation approach is how to map a given Identifier to the appropriate Locator. In this paper, the authors propose a hierarchical mapping system based on Internet hierarchy of IP allocation/assignment authorities. They evaluate their mapping system and show that beside the fact of removing the use of overlay networks scalability, and short look-up time can be achieved.
