Welcome to our Customer Voice series. Today, we are joined by Keith Langridge, Vice President of Network Services, BT as he shares how BT and Nuage Networks from Nokia are working together to achieve efficiencies in next generation networks and serve the IT demands of businesses transitioning to the cloud era.


"BT is proud to have announced the details of our investment in dynamic network services and how we’re integrating a range of new technologies to help our customers succeed in their ambitious digital transformation journeys.

The world is changing

There’s been a rapid increase in the number and types of devices that are connecting in the corporate world. These all have an impact on the network and we’re finding that our customers have a mix of requirements.  They may need high availability and highly secure bandwidth between critical sites so MPLS or Ethernet are still ideal for these needs. But for their branch networks they may look to SD-WAN and for non-critical applications, the internet. And for the vast majority of our customers they need and want a mix of all of these services.  In one of my previous blogs I said it was all about the balance and it really is.

We’re going to launch a new SD-WAN service incorporating technology from Nuage Networks

As a key part of this program of investment, it is great to be able to let everyone know we’ve selected Nuage Networks from Nokia to work with us to develop the technology for our future software defined WAN service.  One of the reasons we picked them was because of their years of experience delivering scalable and highly programmable Software Defined Networking (SDN) solutions. This, along with our own expertise, means we’ll be able to offer best-in-class solutions to give our customers the best possible service.

BT’s SD-WAN service, Agile Connect, powered by Nuage Networks from Nokia, will allow organizations to automate and control network connectivity from any business location to applications hosted in any private or public cloud.

Customers come first

We want to make sure that we have the right solutions for our customers.  We want to be able to offer customers choice, agility, simplification, security, resilience and service.  We believe that our new investment with Nuage Networks from Nokia really helps strengthen the choice of  dynamic network services we can offer our customers."
