[Stephen Hemminger]

This looks interesting: https://blog.apnic.net/2020/09/18/nest-a-simpleefficient-tool-to-study-congestion-control/

Good - using namespaces for testing is a good idea.
     - testbed is GPLv2

Bad - using iperf as your main test tool encourages buffer bloat

    - Does 5G really need yet another congestion control algorithm?
      Or it this just a way to get the grant money?
      Or worse, the start of proprietary TCP congestion control.
