Intent-based Networking: From Vision to Automation

Telecom networks are no longer just the means for connectivity; they are becoming the lifeline of the digital transformation. The emerging application use cases like content streaming, gaming, smart home ecosystems, AR/VR, connected mobility, smart cities, and Industry 5.0 needed a dynamic shift in traffic patterns and service requirements. With the implementation of technologies like 5G, edge computing, and IoT, the network complexity has reached a new level, making it difficult to manage the networks with traditional, manual operations. Intent-Based Networking (IBN) addresses this challenge by translating business goals into automated, enforceable network policies. It automates tasks such as policy creation, configuration deployment, traffic routing, and real-time assurance, reducing dependence on manual intervention. This automation ensures networks remain consistently aligned with business intents while adapting ideally to operational changes, preparing the way for agile, resilient, and intelligent networks capable of powering next-generation digital services.

Figure 1 represents the current and the expected adoption of IBN within the telecom network in the next few years. In 2024, most telecom operators remained at lower autonomy levels (0–2); however, by 2028, their progress toward Level 3 and beyond is expected, with IBN driving AI integration, closed-loop automation, and intelligent network transformation.

This article explores the meaning of IBN and its key features, why it matters for telecom operators, where it is making an impact, and the challenges to adoption. It will also cover the key current and emerging technologies, recent developments, and market insights shaping the next wave, and a future outlook toward autonomous networks, before concluding with key takeaways.

Introduction to IBN

Intent-Based Networking (IBN) represents a transformative leap in network management, shifting from manual device-level configurations to outcome-driven automation. Instead of configuring individual components, operators define high-level intents, such as ensuring 99.99% uptime or prioritizing mission-critical traffic, which the system translates into actionable policies.

By integrating automation, intelligence, and orchestration, IBN enables networks to evolve from reactive management to proactive optimization. This approach delivers greater agility, reliability, and alignment with business and operational objectives.

Intent-based Networking: Architecture

An IBN architecture aligns network operations with business goals by translating intent into policies, automating configuration, and assuring outcomes through continuous analytics and feedback. Unlike traditional or SDN models, it adds a crucial translation layer and closed-loop assurance, enabling networks to operate more autonomously and outcome-driven. Figure 2 presents the IBN architecture along with the key functions of each operational layer.

Intent Translation:

It converts high-level business goals into declarative specifications that define services and infrastructure intent at scale, masking device-level commands. By drawing from a unified and consistent data foundation, it ensures policies remain accurate across diverse domains, reducing ambiguity and enabling precise orchestration of network behavior.

Intent Activation:

It refines high-level policies into device-specific configurations by using the controller’s complete view of the network’s topology and capabilities. This approach ensures that changes are applied safely and consistently across all elements, with safeguards in place to maintain service continuity.

Intent Assurance: It continuously monitors the network, analyzing several telemetries to verify alignment between desired and actual states, while applying analytics to detect issues and automate corrective actions, enabling predictive insights, long-term planning, and predictive correction, ensuring the network evolves reliably while maintaining operational integrity.

Core IBN Features

Figure 3 below illustrates a few of the core capabilities of IBN, which are responsible for driving consistency, automation, and resilient service delivery across the network.

• Single Source of Truth: It unifies configurations across radio, core, transport, and cloud, reducing inconsistencies between OSS/BSS, EMS/NMS, and live networks to ensure operational integrity and accurate service delivery.
• Declarative Specifications: It captures high-level service intents such as quality of service, slicing, and traffic engineering, and translates them into low-level commands using models like YANG or TOSCA, enabling intent-driven orchestration that stays aligned with SLAs and business objectives.
• Automated Validations and Testing: It safeguards mission-critical telecom networks by performing pre-deployment checks, impact assessments, and compliance tests against design rules, SOPs, and regulatory standards.
• Rollback Capability: It enables instant recovery of failed upgrades or misconfigurations, ensuring service continuity and minimizing customer impact during live telecom network changes.
• Closed-Loop Automation and Self-Healing: It continuously monitors network states, detects anomalies, and triggers corrective actions, ensuring resilience and reduced operational downtime.
