BT has launched a new managed comms service that uses software defined networking techniques to automatically optimise network traffic, reports Telecoms.com.

The BT Connect Intelligence IWAN service will, it claims, cut networking costs, boost app performance and tighten security for clients. It unveiled the Walgreens Boots Alliance as a reference customer, which runs in the UK and 20 other countries. Clients can use IWAN as a bridging stage in its transition to full network function virtualisation and software definition in the cloud, it claims.

BT’s IWAN was created by integrating Cisco’s Intelligent WAN (IWAN) service within the BT Connect portfolio of network services. The new offering is a hybrid of public and private cloud and uses Software Defined Wide Area Network (SD-WAN) technology to create virtualised functions such as application performance management and security.

Among the new options offered in this first version of Connect Intelligence IWAN will be a        Virtual Private Network (VPN), fast track application routing, higher rates of app performance and better intelligence on how the network is operating.

The VPNs will be created using MPLS technology and will secure interconnections across hybrids of private and public cloud, as well as fixed line and mobile networks. Meanwhile, despite the powerful levels of encryption set up by the VPNs, information from applications will be fast tracked across the network by the quickest possible route, thanks to intelligence based on real-time network performance. The faster performance of applications will improve productivity and user experience, claims BT. Meanwhile SDN will allow the service provider to gives customers deep insight into their application and network performance, BT claims. The telco claims customers can self-manage their networks through BT’s My Account portal.

The use of NFV and SDN paves the way for a new generation of services that are quicker and easier to set up and change, according to Keith Langridge, VP of network services at BT Global Services. “Customers all over the world can now deal much more effectively with their increasing bandwidth and traffic optimisation demands,” said Langridge.
