Cisco to network engineers: Get comfortable with software. It’s here to stay
The shift to software-defined networks (SDN) was the catalyst to usher in a whole new way of running networks—and that’s through software. Some may argue that network engineers have been using software for decades, as every good router jockey had a laptop filled with scripts and templates that could be cut and pasted into the command line interface. This ad hoc model is highly error prone and not scalable, which is why human error still accounts for much of the downtime with respect to networks.
