A New Hierarchical Network Address Structure Based on Geographical Regionalism

The emergence of IPv6 and ALM (Application Layer Multicast) technology brings a new favorable opportunity for the development of both network structure and network address assignment. Considering geographical regionalism as one vantage point, we propose a new network topology division and network address assignment model which adopts hierarchical and structured method. Then we make a detailed description about this model's routing policy, which is based on field match of the network address. At the end of this paper, we summarize the advantages and the challenge of this model according to the comparison with conventional network.
