Software-Defined Access Networks

Automate more, innovate faster

What is software-defined access?

Software-Defined Access Networks (SDAN) bring platform attributes to the broadband network. It helps operators to realize the evolution of hardware-based networks to software-defined platforms.

This speeds up innovation cycles in a cloud-native environment, leverages cost-effective software platforms to simplify IT integration, and scales up your ability to program and automate your network.

What are the benefits of SDAN?


  • Hardware and software layers can be scaled separately
  • New services and features can be introduced easily  
  • IT-like approach with DevOps and micro-services that yield shorter innovation cycles


  • Operations are abstracted from implementation
  • Provisioning and troubleshooting processes are simplified
  • Portability is maximized for future network evolutions


  • Networks are controlled by software functionality
  • Network routines can be automated and adapted flexibly  
  • OPEX is reduced via closed-loop automation, health analysis and zero-touch operations

Take your broadband into the cloud

The heart of Nokia’s SDAN solution is the Altiplano Access Controller. This cloud-native platform offers a complete suite of network management as well as SDN control functions to run a broadband network.

It provides operators a single view to manage fixed services, leveraging policy-driven operations, powerful intent life-cycle management and real-time automation across a multi-vendor, multi-technology network.

To create an autonomous broadband network, based on open and standardized interfaces for cloud control and multivendor interoperability, explore the Nokia SDAN solution.  

SDN automation is crucial for the digital transformation of broadband access

Geert Heyninck, VP Broadband Networks of Fixed Networks talks about software-defined networking, network automation (SDAN) and cloudification in access.

He explains how Nokia Altiplano gives operators the flexibility they need and how Nokia opens up their SDN platform with industry's first app marketplace for network automation, giving operators the ability to buy, customize, and build unique SDN-enabled applications to automate, support or gain new insights from their networks.

Efficient data telemetry sets the foundation for automation

Advanced automation relies on advanced telemetry to provide access to real-time data which is structured and ready for use by systems. This white paper details the principles of data governance and scalability behind modern push-based streaming telemetry, illustrated with real-world use cases.
