Judging by the amount of traffic many people face on their morning commutes, anticipating demand and traffic flow is often the greatest stumbling block. My daily commute to work is a prime example: I’m stuck in the traffic on a six-lane highway where it converges into just two lanes ahead. As the car inches forward each time, I find myself repeating in my head “Who designed this highway?” Clearly, I didn’t think this was the most brilliant approach to improve traffic flow. Data center managers go through similar thinking processes when designing the network. The design stage is critical; it practically decides the outcome of a project, and most importantly, whether the investments are fully maximized.
