[Bloat] NeST: Network Stack Tester

[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.

Making things easy to test is good, and I generally assume anything said
about 5G is marketing (three drink minimum (;-))

Academics often respond positively to opportunities to make their
metrics better, so we might want to write to them and suggest some valid
follow-on work... to apply for grants for.

Drop me a line if you would like to do so.
