Communication and Security Integrated Space-Earth Heterogeneous Network Architecture

Abstract

To achieve the integration of space information networks and high-speed rail, ship and civil aviation private communication networks, this article proposes to leverage the mechanism of identifi er and locator separation to construct the communication and security integrated space-earth heterogeneous network architecture.The proposed network architecture included four network layers (i.e., space-earth heterogeneous network service layer, space-earth heterogeneous network traffi c layer, space-earth heterogeneous network routing layer and space-earth heterogeneous network access layer) and fi ve network identifi ers (i.e., service identifi er, traffi c identifi er, routing identifi er, access identifi er and host identifi er).With the method of effi cient network identifi er mapping, the communication and security integrated requirement for space information networks and ground private communication networks could be guaranteed.
