Software-Defined Networking for Dynamic Traffic Engineering
Quick fact
In traditional networks, traffic is routed by routers making local decisions—like drivers taking side streets without a global map. SDN instead uses a central controller that can see the whole city and redirect traffic on a whim.
Why this is interesting
Imagine a highway system where lanes could instantly change direction to match rush-hour traffic. That's the promise of software-defined networking—a way to make the internet's roads move in real time.
