[Server-devel] BBR: Congestion-Based Congestion Control

School server networks fail to perform fairly or effectively because
the loss-based congestion control methods in TCP networking are not a
good match for the wireless environment.

Wireless access points or devices with too much buffering memory make
the problem worse.  A case of more not being good.

Former OLPCer Jim Gettys warned us about bufferbloat years ago.

I'd like to hear from anyone deploying the new BBR congestion-base
controls, which should be available in 4.9 kernels.  It is a
server-side feature, so there's no great need for it in laptops that
operate as clients.
