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
