Singapore’s largest telecom company Singtel announced the launch of its new network solution – Singtel Managed Software-Defined Branch (Singtel SD Branch) to support enterprises’ evolving networking needs across the globe.

Highly scalable and cost-efficient through a “white box” or generic hardware, Singtel SD Branch empowers enterprises in managing multiple and virtualized network functions at their existing sites or when they expand into new branch offices.  

With Singtel SD Branch, enterprises are assured of enhanced security and optimal performance of their networks and applications. They can better monitor network usage and issues in real-time. Enterprises can also add new functions, such as unified threat management, to the same hardware without incurring additional installation charges. These will in turn reduce their capital and operating expenditures.

“Many enterprises today deal with challenges of complex hybrid WAN architecture encompassing private and public Internet networks,” said Mr Goh Boon Huat, Vice President, Global Products at Singtel Group Enterprise.

“Singtel SD Branch provides a way to spin up and take down services seamlessly, offers full service visibility and manageability up to the application layer. This simplifies their WAN infrastructure, enabling agile managed network solutions to keep pace with growing business needs in different geographical regions.”

Singtel SD Branch is available globally and integrated seamlessly with Singtel’s underlay assets of submarine cables, IP VPN network of 428 Points of Presence, and its Global Internet service in more than 200 countries.

Developed based on the network functions virtualization (NFV) concept, Singtel SD Branch is the latest addition to Singtel’s suite of next generation SD network solutions following the launch of its SD-WAN in 2015 and cloud-based NFV service last year. Embedded with Singtel’s Security by Design, enterprises’ network services are protected against security breaches.

Singtel’s SD network solutions will help enterprises meet their WAN requirements, and employ a consistent and comprehensive unified portal for end-to-end monitoring, analytics, and visibility into all of their networks and application services. Enterprises are also able to provision new services and scale their network bandwidths on demand.

US telecoms giant AT&T successfully completed the first of a multi-phase trial testing 400 gigabit Ethernet data speeds. This brings AT&T one step closer to quadrupling network speeds for businesses.

In the field trial, AT&T established a 400GbE connection between New York and Washington, D.C. This proved the AT&T nationwide software-centric network is ready for next-generation speeds.

400GbE end-to-end service was transported across the network, which was carrying live traffic. A software-defined network (SDN) controller created a service along the direct path between the two cities, and through software control rerouted the service to a second path to simulate a response to a network failure.  

Late last year, AT&T announced its intention to be the first in the industry to demonstrate 400GbE service across our production network, aligning with its shift toward a software-centric network.

Traffic on the AT&T network continues to grow. 400GbE speeds will allow AT&T business customers to transport massive amounts of data faster than ever. That also means faster uploads and downloads and ultra-fast video streaming.

"Our approach to roll out the next generation of Ethernet speeds is working. We continue to see enormous data growth on our network, fueled by video. And this will help with that growth," said Rick Hubbard, senior vice president, AT&T Network Product Management.

Next-generation speeds like 400GbE can help transform the way AT&T’s customers do business.

The company is moving on to the second phase – a 400GbE end-to-end service transported across the AT&T OpenROADM metro network to the customer. This will show the network is ready for 400GbE to serve customers in metro areas.

Phase 3 will test the first instance of a 400GbE open router platform. The "disaggregated router" platform uses merchant silicon and open source software – another industry first.
