Exploitation of Information Centric Networking in federated satellite: 5G network

With the development of technologies and decreasing of costs, the satellite is expected to play a fundamental role in the 5G era. On the other hand, the Information Centric Networking (ICN) is considered as a promising technology to realize 5G objectives by providing native support for efficient content retrieval while enhancing mobility supporting capability and security. In this article, we exploit the ICN architecture in a federated satellite–5G network to drive a new networking paradigm called Sat5G-ICN. Architecture of the integrated network is proposed and the feasibility of introducing ICN to the dynamic satellite forwarding plane is studied. To ensure the continuity of the ICN service, two solutions are proposed to overcome the reverse path broken problem caused by the instability of satellite links. Simulation results indicate that the proposed approaches can provide reliable ICN services through satellite links regardless of the high dynamic in the satellite constellation.
