摘要：Recent research in the designing of an elegant mapping service to map identifiers onto locators in networks with locator/identifier separation, focuses on solving practical issues related to mapping system. However, how to provide entire secure support in separation networks is still an open issue. In this paper, we present the design and evaluation of a hierarchical indirect mapping system (HIMS). It provides indirect mapping from connection identifier (CID), a novel flat identifier space introduced to stamp packets, to endpoint identifier (EID), can limit the impact of full range of destination attacks such as Denial of Service (DoS) floods from the outset by EID hidden, and fulfills the requirements such as low latency, efficient network utilization and scalability. Based on an efficient merging rule, HIMS build a hierarchical Chord architecture which can scale to Internet level by preserving the locality and convergence of the inter-domain path. We present scalability assessment and numerical results to demonstrate the performance gains of the proposed approach.
