In advance of Network Virtualization & SDN World in London on 27-30 May 2014, we caught up with Ampai Pornprasertsakul, Deputy Director at True Corporation in Thailand, to find out more about her perspective on SDN and NFV in 2014.
Ampai, welcome. What are your impressions of SDN and NFV in telecom networks to date?
AP: “Telecom operations are still in the process of exploring the SDN and NFV capability and impact. The realization is it is coming, and that we shall all need to prepare for it.”
What do you think are the biggest hurdles towards implementing SDN and NFV at present, and how can they be overcome?
AP: “The biggest hurdles that remain are how best to implement SDN and NFV, how to determine the biggest benefits we can get from them, working out how this new technology will impact our existing network, and what exactly the implementation costs will be. We also need to know how best to integrate SDN with network equipment, VAS and IT systems.”
Which areas of the network do you think should be prioritised for virtualization, and why?
AP: “Personally, I think that VAS (Value Added Services) should be prioritised first for virtualization. The reasons for this are the high feasibility of implementation in this area, and that VAS has less impact on key services. I believe that less mission-critical services should be tested first.”
What are your expectations for the development of SDN and virtualization in telco networks in coming years?
AP: “In coming years, I foresee that SDN and Virtualization will continue towards full network implementation. Eventually, I anticipate the integration of network, VAS and IT systems as one.”
