Software-Defined Access Networks

Master your broadband complexity

Take your broadband network into
the cloud

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 by virtualizing much of the functionality. 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.

Open ecosytem

  • Support for cloud-native applications from different vendors and open-source components
  • Integrate easily via open APIs with systems and partners
  • Fostered in open initiatives (BBF, ONF, ONAP and OB-BAA)


  • 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

How to get more value from your fixed network

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.  


SDAN use cases


Network sharing and slicing  

SDAN has introduced a powerful and versatile way to create open access networks. Take a fresh look at your operating models and partition the access network into virtual network slices, that can be commercialized through flexible network-as-a-service (NaaS) consumption models.


Multivendor ONU Connect

The world’s first virtualized Optical Network Unit (ONU) management solution removes one of the biggest headaches in every PON network: ONU interoperability
