This research demonstrates how multi-agent LLM systems can autonomously synthesize verified behavioral network digital twins directly from semantic models, eliminating the need for manual logic implementation. By achieving near-perfect decision agreement in call admission control scenarios, the study validates a scalable path toward TM Forum Level-4 autonomous network management where AI generates its own executable test environments on demand.
NDT Factory: Synthesizing Verified Network Digital Twins from Semantic Models via Multi-Agent LLM
arXiv:2609.12170v1 Announce Type: cross Abstract: Autonomous network management requires systems that can evaluate Network Service Intents (NSIs) under varying conditions without manual implementation of analysis logic, as envisioned in TM Forum Level~4 (L4) autonomy. Behavioral Network Digital Twins (NDTs) enable such evaluation, but existing NDTs rely on pre-defined analytical logic, limiting adaptability for evolving closed-loop control. This paper introduces the NDT factory, a multi-agent software system that synthesizes executable behavioral NDTs on demand from semantic models using Large Language Model (LLM). We validate the system using a Call Admission Control (CAC) case study, where deterministic what-if analysis serves as the admission decision process. The NDT factory generates a complete CAC NDT through parallel synthesis and orchestration, achieving 100% compilation and test pass rates across multiple runs. Simulation over 300 NSIs shows 99.3% decision agreement with a reference implementation, 90% admission rate, and correct attribution of all rejections, demonstrating reliable synthesis with deterministic, verifiable execution.
