Software-defined access networks

Through years of rapid growth in subscribers, bandwidth and traffic, fixed access networks have become diverse, multi-technology environments. Whether copper, fiber or HFC, growing numbers of small, remote and widely distributed access nodes have increased network complexity, service complexity and costs.

Nokia software-defined access networks (SDAN) simplify the network in ways that renew your ability to scale while improving agility and keeping costs under control.Virtualization allows operators to automate the network and unlock new capabilities with smart, cloud-native access.

SDAN use software-defined networking (SDN) and network function virtualization (NFV) to speed up innovation cycles in a multivendor environment, leverage cost-effective cloud platforms that simplify IT integration, and scale up your ability to program and automate the network. Software-defined access networks give you an optimized next-generation access network.

Nokia pioneers with the first cloud-native platform that helps operators get more value from their fixed access network, delivering the widest range of software-defined use cases.

Software Defined Access Networks

Program and automate

By virtualizing the intelligence of the network and centralizing it in software running on top of general purpose (COTS) hardware, networks can be programmed and controlled from the cloud. The open ecosystem with data and configuration in the cloud creates opportunities for automation to focus on customer operations, cutting across FCAPS (fault, configuration, accounting, performance, security) silos.

Open and multivendor

SDAN's modular architecture with open and standardized interfaces can be easily integrated across systems, networks and partners. It allows flexible deployments that can leverage third party/open-source components, existing in your current cloud and IT environment.

NETCONF/YANG compliant

The use of standard NETCONF/YANG protocols enables higher-degrees of automation and transactional consistency. The interaction with the OSS/BSS is less error prone and the underlying models, which are XML-based, are easily extended to provide further abstraction.

Leverage cloud and IT

Adopt a DevOps approach to introduce new capabilities quickly, and scale elastically in the datacenter. Domain-specific controllers deal with functionality that was traditionally embedded in-the-box, taking the load off network elements and deliver an always online experience.

Evolutionary path to SDN

Nokia SDAN products enable traditional and virtualized functionality to exist in the same network, allowing a gradual adoption of SDN/NFV.

Nokia SDAN creates a new way of working that frees up resources and capital and enables new revenue-generating opportunities.

Network monetization

Virtual access networks for service partitioning and open access; increase cooperation and network monetization.

Simplified operations

Network in the cloud is always-on; pre-provision, whether nodes are online or offline; zero-touch and error-free operations.

Virtually unlimited

Update, customize and deploy new access functions and services without touching the access node.

Innovation speed

Fast feedback cycles; DevOps continuous delivery and risk contingency; compliant with YANG standards for immediate interop.

Collaborative ecosystem

Seamless integration via open APIs and software frameworks in cooperative partnerships and multivendor constellations.

Network slicing

Create virtual slices of the network infrastructure to support different services (e.g. residential and business), wholesale, or unbundling.

Cable access provisioning

Reduce power and space by virtualizing CCAP functionality; transparently provision DOCSIS or PON users in a cable access network

G.fast micronode management

Enable automation and zero-touch provisioning; virtualized configuration allows management of all network elements at once, whether online or offline.

5G fronthaul over next-generation PON

SDAN provides optimized PON latency to meet 5G fronthaul delay needs, with cloud-based control and integration

ONT self-activation

Reduce costs through automated activation of ONTs.

Products

Altiplano Access Controller

Create a domain controller for access, uniquely designed for SDN/NFV operations, to simplify IT and OSS integration.

Lightspan CF

The Nokia Lightspan Access Node CF-24W is a compact, high-capacity access node designed to deliver cutting-edge services in a software-defined access network.

Lightspan SX/DX

Programmable G.fast micro-nodes. Automation and zero-touch provisioning enable operators to increase the speed of deployment by 50%.
