Description

It is well known that loss-based TCP congestion control algorithms are problematic for high-speed, high-latency flows that are common in Big Science. In 2016 Google released a new congestion control algorithm called ‘BBR’ (Bottleneck Bandwidth and Round-trip time) that uses a model-based approach, and the design has since been refined in an alpha release of BBRv2. In this paper, we describe and perform a set of experiments that assess the suitability of BBRv2 for use on Data Transfer Nodes (DTNs).
