Intent-Based Networking: A New Era of Automation

Intent-Based Networking (IBN) promises to revolutionize how heterogeneous infrastructures are operated by simplifying the translation of high-level intents into actionable policies. However, achieving this vision of dependable automation continues to be a complex task. The key difficulty lies in the brittle nature of converting ambiguous natural language into controller-compatible policies, often leading to conflicts and unintended side effects.

Realizing Intents: The Challenge

The primary hurdle for IBN is the conversion of vague natural language into precise, enforceable policies. Current systems struggle with ambiguity, resulting in policies that might conflict or generate unforeseen consequences. Developers should note the breaking change in the return type. This issue becomes even more pronounced when multiple intents are involved, as they can create cascading faults and ambiguous telemetry.

A Proposed Solution: Closed-Loop Automation

This paper introduces an end-to-end closed-loop IBN pipeline that leverages large language models (LLMs) for structured validation. The specification is as follows: it aims to automate natural language-to-policy realization and ensure conflict-aware activation. This system transforms assurance into a proactive measure, focusing on multi-intent failure prediction and root-cause disambiguation. The objective is to provide operators with actionable early warnings and interpretable explanations, thus extending the lead time for remediation.

Why It Matters

In a world increasingly dependent on complex networks, the ability to automate and assure policy compliance is key. Without dependable automation, operators face the risk of cascading failures that can cripple infrastructure. This approach proposes a way to mitigate such risks. But can it deliver on its promises? The integration of LLMs with structured validation presents a significant advancement, yet the question remains: will it be operator-trustworthy in diverse, real-world scenarios?

IBN's potential to automate network management could be as transformative as the introduction of cloud computing. However, like any technology in its infancy, its success hinges on overcoming significant obstacles in language processing and multi-intent assurance. Backward compatibility is maintained except where noted below, ensuring that existing systems can adopt these advancements without a complete overhaul.
