It sounds like SDN is another scheme made up to kill hardware vendors. These Telco's and internet service providers must realize that if they kill all of their hardware suppliers just so they can save a few bucks in their network management tools, there will be no one but the Chinese to make hardware for them. I contend the business concept of adapt or die is not going to work in North America because even if you adapt you die. I recall Jetsream, at the height of its business, just simply quit and screwed all of thier cusotmers. Perhaps they were the smart ones, and as time goes on, the NA hardware vendors one by one will bow and take the Jetstream route.
HW vendors seem to resort to touting the performance required to run several virtual machines and services on a single platform. I think the real fear is that SDN will increase the appetite for low-cost hardware (from China) and therefore speed up the commoditization that they're already experiencing.
