5G NWDAF: Powering Intent-Based Networking with Advanced Analytics

Intent-Based Networking (IBN) is emerging as a transformative approach to designing, deploying, managing, and automating complex networks in today's rapidly evolving networking landscape. It allows network administrators to define high-level business objectives and desired outcomes while the underlying network infrastructure dynamically adapts and configures itself to meet those intentions.

At the core of this digital evolution lies the Network Data Analytics Function (NWDAF), a crucial component, a critical enabler that leverages industry-leading intelligence to optimize network performance and enhance user experiences. Moreover, as telcos move to 5G and the role of analytics moves beyond the conventional into a more complex realm, there’s a stronger need for advanced prescriptive analytics to drive closed-loop automation and self-healing computing. There is a strong need for the Network Data Analytics Function.

This article explores how NWDAF plays a pivotal role in building intent-based networks.

The global intent-based networking market size is projected to grow at a CAGR of 25.9% to be worth USD 2.6 billion by the end of 2027

Understanding Network Data Analytics Function (NWDAF)

NWDAF is a key component in the 5G architecture. A 3GPP standard component, it plays a pivotal role in Intent-Based Networking by providing real-time insights and analytics into network behavior, performance, and user demands. It acts as a central analytics engine within the IBN architecture. It is designed to streamline the way core network data is produced and consumed, generate business intelligence, and take action to enhance the end-user experience. 

It harnesses the power of big data and artificial intelligence machine learning to transform vast amounts of raw network data generated from diverse sources within the network, including devices, controllers, applications, and management systems, into meaningful insights. This data includes information about network performance, traffic patterns, user behavior, security events, and other relevant metrics. These insights are then used to optimize network operations, improve performance, enhance security, and enable automated decision-making within the IBN ecosystem. 

How NWDAF Benefits Intent Based Networking

By leveraging NWDAF, intent-based networking can deliver several benefits:

  • Enhanced Network Visibility

NWDAF provides comprehensive visibility into the network's performance, enabling administrators to identify and resolve issues before they impact end-users proactively. This visibility helps align network behavior with intended outcomes.

  • Predictive Network Management

NWDAF's analytics capabilities enable predictive network management, where potential issues and bottlenecks are identified and addressed proactively. By analyzing historical and real-time data, NWDAF can predict network congestion, capacity constraints, and other factors affecting performance, allowing administrators to take preventive actions.

  • Efficient Resource Allocation

NWDAF's insights empower administrators to optimize network resource allocation. By understanding user demand patterns and application requirements, administrators can allocate resources dynamically and intelligently, ensuring optimal performance and efficient utilization of network resources.

  • Adaptive Configuration:

NWDAF enables the dynamic configuration of the network based on the defined intents. By continuously analyzing network data, NWDAF provides inputs for automated decision-making processes that adjust network parameters and configurations in real time. This adaptive configuration ensures that the network adapts to changing conditions and maintains alignment with the intended business objectives.

  • Quality of Service (QoS) Management

NWDAF assesses the quality of service experienced by users, identifying areas where improvements can be made. It helps ensure that users receive the expected level of service, such as low latency, high bandwidth, and reliable connectivity.

  • Network Slice Management

In 5G, network slicing allows the creation of multiple virtual networks within a shared infrastructure to serve diverse use cases. NWDAF plays a crucial role in managing network slices by monitoring their performance and resource utilization and ensuring the fulfillment of service-level agreements.


To sum up, Intent-Based Networking Systems (IBNS) rely on real-time analytics and automation to align network behavior with business objectives. NWDAF serves as the analytical brain of the network, continuously monitoring and interpreting network data to gain insights into user experience, application performance, network resource utilization, and security threats. These insights are then used to optimize network configurations and automate decision-making processes, enabling network operators to make data-driven decisions, proactively identify and resolve network issues, and deliver exceptional services to end users. As the demand for intent-based networking grows, the market for NWDAF is expected to expand further, driven by the need for efficient network management and the rise of 5G networks.
