Published in ACM CoNEXT 2025 Workshop, 2025

Background

Dynamic communication networks with topological changes and multi-dimensional constraints (bandwidth, latency, compute) pose significant routing challenges.

Contribution

  • Proposed a reflective co-evolutionary framework that optimizes task descriptions and routing algorithms via network state feedback.
  • Conducted extensive baseline experiments and ablation studies.
  • Demonstrated superior performance over Optimal and ACO baselines, improving flow acceptance rate by up to 57.49% in 100-flow scenarios.

abstract = {Modern networks demand routing strategies that jointly optimize heterogeneous constraints like bandwidth, latency, and compute resources. While LLM-driven algorithm generation excels in static domains, it struggles in dynamic network environments where these constraints are interdependent and topology-aware. We introduce NeRM-Net, a reflective co-evolution framework that jointly optimizes task specifications and routing algorithms through network-aware feedback. At its core, an adaptive environmental feedback module captures dynamic network states and performance outcomes. This module steers two complementary processes: (i) structure-conditioned prompt evolution, which aligns problem descriptions with graph-level constraints for more effective guidance, and (ii) feasibility-guided algorithm refinement, which evolves routing logic by analyzing constraint violations to improve solution quality. Experiments on Abilene and GEANT topologies show NeRM-Net consistently outperforms baselines in flow acceptance and resource efficiency, demonstrating its effectiveness and scalability.},
