 Welcome to ITU telecom world here in Bangkok, Thailand. Today I have with me Mr Yukio Ito who is the Senior Vice President of Software Infrastructure at NTT Communications in Japan. Ito-san, great to have you here. This is a very interesting event this year and the theme is all about digital change or change in the digital world. What do you see as the biggest opportunities in this changing digital world? For network business industry especially, I believe SDN, Software Defined Networking Architecture, this is really important technologies to innovate at the current network business situations. But what are the challenges that will come with moves towards SDN? Because SDN, its concept is very simple. At the current equipment like a lot of the switching systems is a combined whole of functions, packet of warning function and control functions and some kinds of network application software. Is that the major change though that the network we're going to separate the control plane from the... Yes, yes, because network operation, network equipment operation is still monitored because that is our whole function is one box and those functions are from many kinds of vendors. That's one type of a black box type of equipment. That's why our engineers and our customers engineers and every network engineer have to make it manually. But if SDN architecture is realized, we can completely make our operations like automatically and remotely like almost same of computer technologies situations. How far are we from seeing software defined networks really working across the network and what's it going to look like in say ten years time? So I think maybe from two or three years from now on, it's a very important period to changing those current situations. Many startup company, many current vendors and also many academies and also many service providers. They are very, very interesting, strong interesting to develop those technologies. And I believe from now on, many young and middle and old network engineers shift to like those SDN architectures development because based on hardware, but from hardware base to software base. Software basis is very important because if you are understanding software technologies, if the engineers who can write some kind of software code, they can make any kind of applications, many kinds of functions for our customers. Not only for customers, but also our internal operation too. That means we can change completely our current cost situations, current workflow situations. That's a very, very amazing situation. I think we're all very excited with the prospect of SDN and the effects it's going to have on our networks. Itosan, thank you so much for being with me today. Thank you. Thank you, my pleasure.
