For years, we’ve heard about Software Defined Networking (SDN), and while the hype has been tremendous, we in the engineering community have joked that SDN stands for “Still Does Nothing”. Now that that SDN has been overhyped, marketers have moved on to terms like SD-Access (or SD-WAN) and Digitization. So, when Cisco recently announced their Digital Network Architecture, or DNA, the engineering community reacted with a collective yawn. Just another marketing term, right? Is this just an attempt to erase stale connotations of the first-generation SDN? Not exactly, as it turns out. Where SDN was the automation of network management, Cisco DNA is the automation of the network itself, or “digital networking”.
