Network architecture using network address translation mechanism for network with unidirectional links

摘要

In this paper, we present a network architecture using satellite communications(a wide-area unidirectional com- munication medium)and a ground network(a two-way communication medium)that is effective in an environment exhibiting a trend toward nonsymmetrical traffic, as well as the implementation of such an architecture. Unidirectional data transmission channels have poor compatibility with the existing Internet routing control architecture, and they do not make the best use of wide-band unidirectional links offered by existing routing control techniques used in the satellite communications.
