Abstract

In current Internet applications, naming is constructed by the location of host and the resource in the host, and name resolution mapping system is constructed by a treelike domain name system (DNS). These architectures has some shortcomings, such as not supporting data migration and replication, vulnerable to Denial of Service (DoS) attacks. Researchers have proposed a DHT-based flat structure to achieve naming and name resolution mapping. to deals with the shortcomings of DNS above, but it introduces a new problem that the resolution time cost is too large that users often can not tolerate this long delay. In this paper, we present an improved structure called Hierarchical Name System (HNS) by combining the advantages of DNS and DHT. The architecture of HNS is a two-layer's structure, namely top-layer which maintains the global information and bottom-layer which maintains local information. Owning to the location information, the resolution delay is greatly reduced while the shortcomings of DNS have been eliminated.
