along the way (in the old days people in the routing
This is an excellent RFC. It should be issued immediately. It should also be
(along with fq_codel) cited as one alternative for managing queues properly in
a new version of a best practices RFC. There may be alternatives of similar
quality, but those alternatives should have quantitative
All the points below make sense. Ideally you want to measure the TCP FQ Codel
interaction in the real world. Throughput benchmarks are irrelevant, the
equivalent of Hot Rod amateur dragstrip competitions among cars that cannot
even turn corners.
Beyond being hard, there is no agreed upon
