Abstract: High-dynamic power optical networks are characterised by frequent topology changes and resource constraints, which challenge traditional routing mechanisms in meeting quality-of-service requirements. This paper proposes a multi-path deep Q-network (DQN) routing mechanism tailored for such environments. By integrating multi-path transmission with deep reinforcement learning, the mechanism optimises delay, packet loss rate, and load balancing through a multi-objective reward function. Built upon a layered graph model of the optical network, the approach incorporates a multi-path selection strategy and employs DQN for intelligent routing decisions under dynamic conditions. Simulation results demonstrate that the proposed mechanism effectively reduces end-to-end delay and packet loss under high traffic loads, while improving resource utilisation and network robustness, making it suitable for efficient data transmission in high-dynamic power optical networks.
Keywords: high-dynamic optical networks; multi-path routing; deep Q-network; DQN; deep reinforcement learning; load balancing.
