In advance of Network Virtualization & SDN World in London on 27-30 May 2014, we caught up with Haim Geron, Senior Deputy Director-General, Israel Ministry of Communications, to find out his thoughts on progress within the industry in 2014…
Haim, welcome. What would you say has had the largest impact in terms of progressing SDN and NFV in telecom networks to date?
HG: “I believe that the recognition by major manufacturers like Cisco, HP and Juniper, major Software co. like VMware and announcements by application giants like Facebook about the development of Open Source based applications contributed to the rapid progressing of SDN and NFV to date.”
Do you feel that the industry is making as much progress towards implementing SDN and NFV this year as you would like?
HG: “Telecommunications experts always feel that the progress towards implementation is NOT what they would like and again and again get “disappointed that it takes roughly 10 years from concept to mainstream implementation. However, we see some positive signs that the adoption of SDN/NFV architecture my “break” the 10-year barrier.”
How is your company contributing to the realisation of SDN and NFV at present?
HG: “As a regulator, we favor any technical advance that may reduce cost for operators and eventually, some of the cost savings will be transferred to consumers.”
What do you think are the biggest hurdles towards implementing SDN and NFV at present, and how can they be overcome?
HG: “I believe that the current, huge ‘sunk cost’ of legacy networks imposes the biggest obstacle to the rapid implementation of SDN/NFV. One way of overcoming that is to lower the entry-level barrier for new service providers who did not yet make a significant CAPEX in legacy networks. Another way is to devise sophisticated acquisition plans for SDN/NFV systems so that the CAPEX+OPEX of these new systems will be less than the long-term OPEX of the installed legacy systems.”
Which areas of the network do you think should be prioritised for virtualization, and why?
HG: “Obviously the Core Network will be prioritized because that’s where the applications get prioritized. In the access network, be it mobile or fixed, ‘a bit is a bit’.”
What are your expectations for the development of SDN and virtualization in telco networks in coming years?
HG: “Reducing cost for the benefit of consumers, flexibility in the development of new services and a fair and proper implementation of Net Neutrality principle.”
