Abstract

This paper evaluates the fairness of BBR congestion control using NS-3 simulator. While BBR improves performance over loss-based methods in single flows, unfairness issues emerge with competing BBR and BBR/Cubic flows. Unfairness correlates with factors like round-trip time and buffer size. The core reason is the lack of responding mechanisms for the flows to converge on fair bandwidth share.
