Google's Network Congestion Algorithm Isn't Fair, Researchers Say

'Researchers at Carnegie Mellon University say a Google algorithm
designed help reduce internet congestion is mathematically unfair,
resulting in network management systems that may disadvantage some
traffic over others. From a report:

Several years back, Google began work on a new open source congestion
control algorithm (CCA) designed to improve the way the internet
functions. The result was BBR, short for Bottleneck Bandwidth and RTT
(Round-Trip Time). The goal of the project: to improve how network
packets travel between servers to mitigate congestion on the internet.
CCAs have long been used to help manage congestion -- ideally while
treating all traffic equally. But in a study unveiled last week at the
Internet Measurement Conference in Amsterdam, researchers revealed
that BBR doesn't actually do a very good job of that last part. In
fact, they found that during periods of congestion, BBR connections
would take up 40 percent of the available bandwidth, leaving the
remaining 60 percent to be fought over by the remaining users on the
network.'
