The networking industry is in the midst of a transition to the digital era. The network plays a critical role in the success of digital businesses as many of the digital building blocks, such as IoT and the cloud, are network-centric. This is one of the reasons why there is currently so much focus on network evolution. Technologies such as SDN, SD-WAN, WiFi, segmentation are currently red hot.

However, before moving forward, it’s critically important to go through the exercise of establishing a network baseline. In actuality, setting a network baseline will provide value regardless of whether the network is being evolved or not. Understanding the current state of the network can have many benefits, including planning for growth.

A few weeks ago I presented on the state of Software-Defined Networks (SDN) at this years Open Networking User Group (ONUG) conference. During the section on SD-WAN I made a comment that I thought that hybrid WAN was an unnecessary step on the journey towards a broadband WAN. It appears I touched a nerve on that topic — the minute I stepped off the podium I was inundated with people asking to me to explain myself further — so I thought I would give more details.

I moderated a workshop on the topic of software defined WANs (SD-WAN) last month and I’m continually baffled that the focus of software-defined networking remains on the hardware for so many individuals. This is clearly a hangover from the early days of SDN when many of the start ups were hammering home the point that hardware is expensive and businesses should move to a software-defined model and cut capital costs.
