Research on Resource Allocation Method of the SIN Based on SDN

Aiming at the resource allocation problem of space-based information network (SIN), this paper firstly establishes the control architecture of the SIN based on software-defined network (SDN). On this basis, in order to realize the unified management of the SIN transmission, caching and computing resources, the A3C algorithm in deep reinforcement learning is introduced to model and simulate the resource allocation process. Simulation experiments show that the proposed scheme can effectively improve the expected benefits of unit resources and improve the resource utilization efficiency of the SIN.
