Satellite Network Architecture Design Based on SDN and ICN Technology

In order to solve the problems of traditional integrated space-terrestrial network control and service deployment complexity and large request delay of streaming media data such as video in big data environment, this paper proposes ContentSDSN architecture. By introducing the idea of SDN and ICN, on the one hand, SDN framework is used to simplify the control of the integrated space-terrestrial network and improve the efficiency of network service deployment; on the other hand, by using of the inherent request aggregation and data distribution capabilities of network forwarding nodes, as well as the forwarding node has high sensitivity to content and optional cache features, in order to achieve the overall performance of the integrated space-terrestrial network upgrade. The simulation results show that ContentSDSN architecture has the advantages of flexible network control and small request delay compared with the integrated space-terrestrial network architecture.
