Advanced Intelligent Frame Generation Algorithm for Differentiated QoS Requirements in Advanced Orbiting Systems

In order to efficiently transmit spatial data with diversified service types, this paper proposes an Advanced Intelligent Framing Algorithm (AIFG) for Advanced Orbiting System (AOS), based on the virtual channel multiplexing AOS technology, aiming to meet differentiated quality of service (QoS) requirements. To enable the timely transmission of delay-sensitive services, the optimal time threshold for framing such services is modeled as a Markov decision process (MDP). The algorithm utilizes Proximal Policy Optimization (PPO), achieving an optimal solution based on performance metrics such as frame multiplexing efficiency, average framing time, and average packet delay. To improve the multiplexing efficiency of non-delay-sensitive services, this type of traffic is transmitted only after completely filling a frame. Simulation results show that, compared to traditional frame generation algorithms, the AIFG algorithm reduces the average queuing delay of services by an average of 32%. Moreover, the AIFG algorithm increases throughput by an average of 32%, and improves multiplexing efficiency by an average of 61%. Thus, the AIFG algorithm balances the transmission requirements of both real-time and non-real-time services, and enhances the QoS of the AOS.
