AT&T and Colt Technology Services have announced a successful trial of software-defined networking (SDN) interoperability between two networks in the US and Europe, a landmark which AT&T said will accelerate the commercial adoption of SDN. AT&T and Colt trialled a standard application programming interface (API) infrastructure, which enables SDN architectures from different network service providers to interoperate with each other, in this case provisioning network services between the east coast of the US and various locations in Europe.
AT&T added that the successful SDN-to-SDN control – using a programmatic API-to-API interface between the separate SDN architectures – proved that SDN-managed services can be set up and run across multiple networks in ‘just minutes’. According to AT&T’s release, the proof of concept also ‘reveals that users could reserve ports, order a point-to-point Ethernet service, flex the bandwidth up and down and turn down the service in near-real time’.
AT&T and Colt expect that their integrated on-demand network capabilities will drive further industry collaboration and standardisation, and plan to share the network-to-network interface and open API code with standards bodies and industry forums.
Roman Pacewicz from AT&T Business Solutions commented: ‘Businesses looking to provide a seamless connected environment for their customers can benefit greatly from a unified industry ecosystem that’s focused on interoperability.’ Rajiv Datta, CTO at Colt, added: ‘This proof of concept is a key building block giving enterprises the power to provision scalable, flexible network services on-demand … As use cases and APIs continue to evolve, we’ll be able to add attributes, services and enhancements that will drive further innovation. This will be critical as SDN becomes increasingly important in our business climate.’
