Re: SDN & Mobile Backhaul The next challenge for us is to analyze this suddenly prevalent feeling that SDN is under-hyped. What does that really mean? If a new technology takes several years to play out, but still has a major effect on the industry, it is not necessairly under-hyped now. I'm wondering if it is still over-hyped in the sense that some people might think the transformation will happen much sooner.

Re: SDN & Mobile Backhaul More than one operator here echoed the underhyped sentiments. I think a lot of new vendors were excited about it because they saw SDN as a way to get their foot in the door and level the playing field, but we're already seeing some operators stick with what they know. And, established vendors are certainly making more noise about SDN now too. It'll be interesting to see how that plays out.

Re: SDN & Mobile Backhaul I agree that SDN is under hyped. Seldom has something come along that can so radically change the way networks are deployed and also the relationship of the network with the upper layers. But I also think the adoption of SDN mgith take some time because it so different. It will also be interesting to see if the new vendors have a chance with the major carriers--or will the major carriers favor existing vendors in the adoption of SDN.

SDN & Mobile Backhaul The mobile backhaul panel was really interesting. On the topic of SDN, the panelists suggested the biggest benefit would come in the reduction of opex. Jim Heney, from Canoga Perkins said: "SDN will have a big, positive impact. We'll start seeing those coming up here fairly soon."

And, Carol was spot on about the ability to move traffic patterns on demand. That's something Bruno Gigure from EXFO talked up, noting that traffic patterns depend a lot on time, so being able to switch the bandwidth around will be helpful. "You can throw a Gig at a tower only when you need it," he said.
