One of the goal of SDN is to have more control of how network works. With SDN, the network will be able to route different traffic differently. The Internet will run more efficiently. One of the many questions that I have is how the trade is done. Traditionally, ASIC will run faster than firmware and, firmware will run faster than application on top of OS. I believe it is still true. Then, is the current processor fast enough to offset the extra load due to the operation of OS? On the other hands, the success of a technology is not only relied on the technology itself but also on the business model. What do network operators and ISPs want to accomplish in the business side? No one owns the whole Internet. Internet is built by interconnecting different networks together. With Openflow/ SDN, does any network operator have control of an end-to-end route? What will be the features that Openflow/ SDN can empower the business?

SDN is virtually off loading the firmware onto the Server OS and strengthening the network operation with more resources and dynamics. OpenFlow will be having its very early stage but it is industries requirement. Also ASIC and SDNs are not rivals but they will complement each other to get better out of networks.

I am wondering about the performance of SDN vs ASICs for routing the huge traffic load that the internet represents. Perhaps there will evolve a middle ground sort of a hybrid between hardware and software routing of network traffic, I would think that the combination would be more powerful and yet still flexible than an either or solution.
