Bottleneck Bandwidth and Round-trip propagation time is a congestion control algorithm for TCP.
Bottleneck Bandwidth and Round-trip propagation time is a congestion control algorithm for TCP.
This algorithm is an improvement the over previous TCP loss-based congestion control CUBIC algorithm.
The impetus for the improvements were based on the changing face of the Internet, and differences in current traffic compared to traffic using previous generation technology. In the 1980's, packet loss and congestion were synonymous, due to technology choices of that day. Due to other changes made since then, packet loss and congestion no longer have a direct correspondence with each other, leading to the need for an improvement in this TCP algorithm.
