IG1251D AN Agent Architecture v1.0.0

This guide defines the target architecture for achieving Level 4 autonomy in network operations, based on the TM Forum IG1251 Autonomous Networks Reference Architecture. It presents both functional and solution perspectives: the Functional Architecture outlines modular, AI-enhanced capabilities across Business, Service, and Resource operational layers, while the Solution Architecture details their realization through autonomous agents and copilots. Aligned with high-value scenarios and TM Forum standards, this document provides CSPs with a structured, phased approach to implementing scalable, intent-driven, and closed-loop automation.
