The paper is pretty coy about what they mean by "network", "congestion" and "latency". It doesn't just apply to computer networking -- the original motivating example for this kind of model was road network traffic, and it also applies to things like choosing which bus to take to work with some "overcrowding discomfort" function. This research could motivate how self-driving taxis are routed through a city. The Braess network example shows that cooperative routing could decrease everyone's travel times simultaneously compared to the "everyone takes the shortest path given traffic" Nash equilibrium (called "Wardrop equilibrium" in the continuous network flow domain.)
