CMU Researchers Find Google's New Congestion Control Algorithm Does Not Treat Data Fairly


Even when adding more users to the network, Google's algorithm does not release any bandwidth.

Carnegie Mellon University researcher have found that a new congestion control algorithm developed by Google may compete unfairly with other services on overloaded networks.

Researchers at Carnegie Mellon University have shown that a new congestion control algorithm (CCA) developed by Google may compete unfairly with other services on overloaded networks.

The new BBR algorithm would take up to 40% of the bandwidth of a given network, leaving the remaining 60% to be split between the other parties on the network.

When only two users are sharing the network, BBR takes its normal 40%, but as more users are added to the network, BBR keeps its 40% and leaves the rest to be divided up into smaller and smaller portions.
