Reinforcement Learning-Based Method for the UELB Problem with Network Node Load Consideration

Abstract (in Japanese) (See Japanese page) 
(in English) This study investigates a routing method that considers node load for the Unsplittable flow Edge Load factor Balancing (UELB) problem. Existing RL-KSP methods mainly focus on edge load factors and do not explicitly consider node capacity differences or load concentration at intermediate nodes. To address this issue, we extend RL-KSP by estimating node capacity using a simplified IPPBMT model and incorporating the resulting node load factor into the reward design. Simulation results on the NSFNET topology show that the proposed method can suppress node capacity violations, while edge load factors may degrade in some cases.
