Interview with Hugh Bradlow, CTO, Telstra, Australia

Hugh BradlowIn advance of Network Virtualization & SDN World in London on 27-30 May 2014, we caught up with Hugh Bradlow, CTO of Telstra, Australia, to ask him about his thoughts on SDN and NFV in 2014.

Welcome Hugh. What would you say has had the largest impact in terms of progressing SDN and NFV in telecom networks to date?

HSB: “Cloud data centres have had the biggest impact on progressing SDN as they offer immediate value.”

Do you feel that the industry is making as much progress towards implementing SDN and NFV this year as you would like?

HSB: “Any change to core infrastructure cannot be rushed, so the pace of introduction is valid.”

How is your company contributing to the realisation of SDN and NFV at present?

HSB: “We have been running trials of some of some the key new use cases (e.g. virtualised Residential Gateway) to determine value and performance.”

What do you think are the biggest hurdles towards implementing SDN and NFV at present, and how can they be overcome?

HSB: “The hurdles are similar to the introduction of any new technology. You are competing with an incumbent infrastructure which is delivering value and the technology is usually only a small proportion of the overall solution – the aspects that inhibit change from existing to new are all the things that go with the technology – OSS, OAM, human capital, etc. On top of that, you need to prove a business case based on total operating cost which is always difficult.”

5) Which areas of the network do you think should be prioritised for virtualization, and why?

HSB: “As mentioned above, data centres are an obvious use case and are already well progressed. Customer access is another priority opportunity because of the flexibility it allows in terms of service delivery (e.g. enabling a customer to configure multiple independent networks over one physical access path).”

6) What are your expectations for the development of SDN and virtualization in telco networks in coming years?

HSB: “Unless some compelling use case emerges, I think we shall see the introduction of SDN/NFV as part of lifecycle replacement of assets over time.”

Hugh Bradlow will be speaking in more detail about his thoughts and ideas at Network Virtualization & SDN World in London on 27-30 May 2014. For further information and to register for the event, please visit www.sdnworldevent.com.

Speaker Interview: Ravinder Shergill, Senior Technology Architect, Telus, Canada

Ravinder ShergillWith Carrier Network Virtualization just around the corner, we caught up with another of the show’s speakers, Ravinder Shergill, Senior Technology Architect from Telus, Canada. Here are a few of his thoughts on the nature and growth of the NFV and SDN industries in 2013/4: 

RS: “We’re living during exciting times, with the opportunity to effect technological innovations for years, and perhaps decades to come.

“With incredible data growth and significance of cloudification, business as usual will not suffice. New and innovative models must be explored, and SDN and NFV hold the promise of such potential. First solution sets are targeted at the Data Center environment, and the greatest opportunity lies there. However, the opportunities landscape is much broader.

“The SDN and NFV eco-system is currently in transition, but as the roadmaps and the standards solidify, it will pave the way for easier acceptance

“Small adoptions, perhaps as pilots, are imminent, but broad deployments are further away, perhaps even 5 years out. As the SDN and NFV eco-system develops, this will pave the way for gaining traction in the industry. While there has been good progress in 2013, there is a long journey ahead.

“At Telus, we are now at the Proof-of-Concept stage, and the outcomes of these will determine our future plans.”

You can hear more about Telus’ ideas and plans regarding SDN and NFV at Carrier Network Virtualization in Palo Alto on 9-11 December 2013. For further information, please visit www.carriernetworkvirtualization.com 

SDN Bulletin: October 2013

bbwfIt’s been a busy month full of industry meetings, the most recent of which was the Broadband World Forum in Amsterdam last week.

Marc Cohn, Chair of the Market Education Committee for the ONF, highlighted an interesting differentiator between SDN and NFV, in that SDN can provide considerable OPEX savings for telcos and carriers, while Virtualization holds more promise for lowering CAPEX. Together, SDN and NFV hold the potential to transform telco networks substantially for the better, but monetisation will always be the greatest driver for change.

Meanwhile, Antonio Manzalini from Telecom Italia put forward a positive assessment of the continuing growth of the SDN and NFV markets, stating, “The most profound technologies are those that disappear and weave themselves into the fabric of everyday life” – if applied successfully, this could well be the case for both technologies in 20 years’ time.

Don Clarke from BT, Chair of the Network Operator Council for ETSI NFV ISG, also gave a valuable update on the ETSI group’s activities to date and outlining their plans in the future. (Please see a ETSI’s tweet below to access their recently-published NFV specification documents).

Don also predicted that SDN and NFV-related conference agendas will look very different in 2014 from those of this year, as more and more use cases are established and SDN and NFV move out of the ideas phase towards mainstream use.

Indeed, we already have over 20 carriers confirmed to present at Carrier Network Virtualization in Palo Alto on 9-11 December 2013 and this number is still rising: www.carriernetworkvirtualization.com.

Plans for our annual Network Virtualization and SDN World conference and exhibition in London on 27-29 May 2014 are also taking shape. If you have any ideas for the programme which you would like to feed into this, please do get in touch, as the research process for this is now beginning.

All the very best to you this autumn. Please find below a round-up of what we’ve spotted this month…

SDN to cause a paradigm shift for telcos, says Telefonica

Diego LopezDiego Lopez is Assistant Technical Manager of ETSI’s Network Funictions Virtualisation ISG and Head of Technology Exploration in the Global CTO Unit of Telefonica, Spain. In advance of SDN World, we caught up with him to ask him about Telefonica’s outlook on SDN and his thoughts on the growth of the industry.

Diego, what is the significance of SDN for telcos?

“My view is that SDN will bring to networking a dramatic change (a “paradigm shift” is the term I’d employ if it had not become a little bit too overused), very similar to what Java meant for applications fifteen years ago. Things are going to change, though very probably not in the exact way we foresee now. And, as you can imagine, if such a dramatic change to networking occurs it will involve practically every network operator, at all levels.”

Why is carrier-class SDN so important?

“Essentially, because we are carriers! 🙂 Seriously speaking, SDN has proved its applicability in data centre environments, highly regular and homogenous not only in the infrastructure itself but also in what relates to the use of a limited set of protocols, reasonably controlled application usage patterns, and a highly centralised control and supervised operation.

“Moving SDN into much wider networks implies not only addressing the challenges about extremely high resilience with necessarily decentralised control, but the ability to address the high heterogeneity at all levels that characterises current network infrastructures.”

How quickly do you think SDN and NFV will become a reality?

“It is already happening, and I do think it will bring a snowball effect: the more environments where these techniques are applied the more other environments in which their application will become appealing. It is true that we are at the beginning of the slope, but I think that the interest and commitment of the whole industry (operators and vendors) is clear, compelling use cases have been around for a while, and real-life demonstrations are about to start.”

What do you think will be the best use-case scenarios for SDN and NFV?

“I’d reverse the question: what scenarios are not extraordinarily appealing for SDN and NFV? None I can think of. And the most appealing to me are those related with the possibility of providing powerful abstractions, easing the definition of E2E services over heterogeneous networks in dynamic way. I have sometimes referred to it as finding the equivalent in networking to what SQL was for database technologies.”

How does Telefonica intend to use SDN and NFV in coming years? What difference will it make to your ongoing operations?

“Virtualisation, with SDN and NFV being terms of the general equation, is one of our key strategies for network evolution. It will translate in much more flexible infrastructures, centred on the user, and able to provide a much better experience at lower costs of operation. The phased approach we have in mind, aligned with the pace of infrastructure updates, will help us in making such a deep change much smoother.”

Diego will be detailing Telefonica’s vision in greater detail at SDN World in Barcelona on 11-13 June 2013.
