Huawei Huawei Huawei Huawei Huawei Huawei Huawei Large Language Models (LLMs) are entering network operations through natural-language intent interfaces. Existing south-bound protocols (NETCONF, RESTCONF, gNMI, MCP, A2A) were not designed for conversational, semantically-rich, multi-agent orchestration. This document provides a systematic gap analysis and identifies extension points for each protocol to meet intent-based networking requirements.
