Traffic Engineering
Traffic Engineering is a way of managing how data moves through computer networks to make sure everything runs smoothly and efficiently. It's like being a traffic controller for digital information, making sure data takes the best possible routes and preventing network congestion. Network professionals use Traffic Engineering to make sure important services like video calls or critical business applications get priority and run without interruption. This is especially important for internet service providers and large companies that need their networks to perform reliably.
