GCN-Based Multi-Agent Deep Reinforcement Learning for Dynamic Service Function Chain Deployment in IoT
Bibliographic record
Abstract
The rapid development of technologies such as the Internet of Things, SDN/NFV, and 6G is driving up the demand for dynamic deployment of service function chains (SFC). These technologies are making network architectures more complex and service deployments more dynamic and adaptable. More than ever, there are situations that call for multi-objective SFC dynamic deployment, which necessitates resource game optimization across multiple objectives. For the first time, multi-objective optimization in dynamic SFC deployment scenarios is realized using a multi-agent deep reinforcement learning system based on graph convolutional network (GCN) in this study. Here we mainly focus on the game optimization problem of two objectives: minimum delay time and minimum resource utilization. Three sample complex networks are used to evaluate the proposed methodology: Random, BA scale-free, and Small-world. The results of the simulation indicate that the proposed method can be well applied in IoT scenarios. In general, this method is superior to other mainstream methods in terms of reward and convergence performance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
