Suffice it to say, to this day, we still don't know what SDN means to us, hehe.
Hi Mark, The Software Defined Network concept started as, "Let's use commodity hardware running commodity operating systems to form the control plane for our network devices." The concept has expanded somewhat to: "Lets use commodity hardware running commodity operating systems AS our network devices." For example, if you build a high-rate firewall with DPDK on Linux, that's now considered SDN since its commodity hardware, commodity OS and custom packet handling (DPDK) that skips the OS. This is happening a lot in the big shops like Amazon that can afford to employ software developers to write purpose-built network code.
