Nokia Introduces SDAN Solution

By Paula Bernier October 10, 2017

Nokia has unveiled a Software-Defined Access Network solution. This offering consists of cloud-native software, integration services, open programmable hardware, and scalable deployment practices. And it’s been in trials with many carriers, including du, nbn, and SK Telecom.

“The Nokia Lightspan family delivers programmable access nodes, specifically designed for SDAN use cases, which bring data center practices to the central office and introduce cloud and operational agility to the copper/fiber outside plant,” the company explains. “The innovative and compact Lightspan hardware comes with powerful processing, increased throughput and power-efficient design.”

It features a 16-port reverse-powered micro-node called the Lightspan SX-16F. That can be safely reverse-powered from the home, Nokia explains. And it includes the Lightspan CF-24W. That’s a stackable software-defined optical line terminal. It provides very high next-generation PON capacity in a single one-rack unit. 

This new offering makes the network smarter, controls cost and complexity, allows for scalability, and enables operators to avoid vendor lock-in, Nokia explains. It can support automated operations, cloud-based provisioning, data center practices, edge cloud architectures to enable 5G and IoT applications, network slicing, virtual access networks, and wavelength mobility.

The cloud-native software platform is called Altiplano. It leverages open networking technology including BBF and CORD, and solutions from ON.LAB, ONAP, and the Open Networking Foundation.

Altiplano takes the network functionality that once resided in access equipment and instead centralizes and virtualizes it. That allows for the elimination of network management silos and the auto-alignment of the network, Nokia explains.

"Nokia SDAN lays the foundation for fixed operators to change the economics of their business with cloud agility and software-driven automation,” says Teresa Mastrangelo, Principal Analyst at Broadband Trends. “Nokia SDAN is putting virtualization to work, focusing on real-world benefits for operators and end users, addressing investment protection and improving scalability with industry-leading powerful access nodes. With this announcement, Nokia has the opportunity to lead operators into this new era of software-defined access networks."
