Telus' Gedeon: SDN Key for Automation of New Functions & Features![]() Ibrahim Gedeon, CTO, Telus, 8/31/2017
Software-defined networks are the linchpin technology to a complete transformation of carrier networks, according to Telus' Senior Vice President and Chief Technology Officer Ibrahim Gedeon. In the first part of a two-part Q&A with Telco Transformation, Gedeon spoke about how SDN was a key enabler for automation as well an important element for the migration to 5G and other new areas. One of the biggest hurdles to overcome when implementing SDN is the human element, according to Gedeon. He also stressed the importance of keeping a keen focus on "Day 2" operations and the total cost of ownership. Telco Transformation: Please describe Telus' use of SDN, including what stage of deployment it is in, when the main work will be finished and the overarching goals. Ibrahim Gedeon: Telus is currently the only major Canadian service provider -- and one of the early adopters globally -- to have an SD-WAN service launched in the market to enable a seamless path virtual connectivity and services. Some of the ways we're using SDN include service chaining, automating deployment, reducing cost as well as dynamic provisioning and network occupancy and programmability:
TT: What is the biggest challenge of an SDN deployment? IG: The overarching challenge with SDN deployment is the human element. Rethinking our industry's model of operations and networks requires a tremendous amount of discipline and cooperation. I cannot stress the importance of ensuring "Day 2" operations and the need to evaluate the holistic total cost of ownership. Brownfield, or existing infrastructure, requires integration of legacy physical network functions and the systems supporting them with SDN solutions. To realize the benefits of virtualization and automation one must also realize that the technology itself plays only one part of the end-to-end transformation that is required. Transformation also means taking advantage of this technology cycle to simplify. Let's resist the urge to cause additional complexities by adding pieces such as ONOS, OpenStack and various orchestration/MANO initiatives. This transformation also requires us to upskill our people, and update our structures and processes. Addressing these challenges will be critical to our industry's success and ensuring telcos can adapt to the future. TT: In February 2016, Telus Corp. (NYSE: TU; Toronto: T) announced that it would invest about $2 billion to upgrade infrastructure in Quebec. Is SDN part of the project? If so, can you describe the progress? IG: SD-WAN is a critical step in how Telus will evolve our major infrastructure presence into 5G, namely mobile edge, centralized RAN and small cell deployments. When we launched SD-WAN and Network-as-a-Service (NaaS) we did so nationally and included the province of Quebec. This year will also see Telus building an NFV presence in Montreal, which will include SDN. Overall these investments will help us move functions closer to customers in order to up-service remote communities and improve performance while keeping it as cost effective as possible.

![]() In part two of this Q&A, the carrier's group head of network virtualization, SDN and NFV calls on vendors to move faster and lead the cloudification charge.
It's time to focus on cloudification instead, Fran Heeran, the group head of Network Virtualization, SDN and NFV at Vodafone, says.
5G must coexist with LTE, 3G and a host of technologies that will ride on top of it, says Arnaud Vamparys, Orange Network Labs' senior vice president for radio networks.
The OpenStack Foundation's Ildiko Vancsa suggests that 5G readiness means never abandoning telco applications and infrastructures once they're 'cloudy enough.'
IDC's John Delaney talks about how telecom CIOs are addressing the relationship between 5G, automation and virtualization, while cautioning that they might be forgetting the basics.

Orange has been one of the leading proponents of SDN and NFV. In this Telco Transformation radio show, Orange's John Isch provides some perspective on his company's NFV/SDN journey.
