Address space separation is an effective solution to the scalability of Internet routing, key technique of which is the address mapping mechanism from edge network to core network. Currently, all typical address mapping models are designed based on caching of mapping items, which require complex control protocol and bring great cost to PEs. Moreover, delay of address mapping lookup is so long as to severely impact the experience of network users. In this paper, we propose a novel model, AMIA (Address Mapping for Inter-AS), in which mapping messages transferring are fulfilled through BGP extension without any caching mechanism. Therefore, AMIA is very easy for practical deployment. Besides, we also develop the novel router integrating functions of PE&KMS and construct an experimental network on CERNET2 to validate AMIA model. Both theory analysis and experimental results show that AMIA is of high performance, feasibility and easy implementation, etc.
