Abstract

Abstract: In the context of satellite network communication services with complex requirements and poor service compatibility of on-board equipment, a software-defined network (SDN) architecture for low-orbit satellite network was proposed. A virtualized data plane based on inter-satellite links and a distributed control plane with multiple controllers were designed in this architecture, which was highly flexible and programmable. Through the network function virtualization (NFV) technology, the data plane virtualization and the functional division of the clustered controller were realized, and the key technical solutions for the realization of the architecture were given to enable the efficient and dynamic allocation of data transmission. The simulation verifies that the SDN satellite network architecture is more stable than the traditional satellite network in the reverse seam scenario in terms of fast route reconfiguration. In the simulation results, the average reconstruction delay is shortened by 82.4%, and the scientific choice of the number of controllers is verified. The simulation results reflect the advanced nature of the SDN satellite network architecture.

Key words: LEO, satellite communication, SDN, NFV, controller integration
