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.Read more of this story at Slashdot.
