Networking actually has tons of interesting and complex math. Congestion control is a rabbit hole of math and control theory.

I ended up reading quite a bit about congestion control while investigating a different issue (sending data from a 25gb box to a 1gb one over a 10gb/100ms latency link didn't work well since the bigger nic would saturate the smaller one which then dropped packets, and this caused the tcp window to shrink significantly ), and it was extremely interesting. The whole problem of having multiple agents competing with different strategies and incomplete information to maximize their network throughput also reminded me of economics. Tcp pacing essentially solved the problem (and if not available brutally traffic shape).
