Struct quinn_proto::congestion::Bbr

source · [−]

pub struct Bbr { /* private fields */ }

Expand description

Experimental! Use at your own risk.

Aims for reduced buffer bloat and improved performance over high bandwidth-delay product networks. Based on google’s quiche implementation https://source.chromium.org/chromium/chromium/src/+/master:net/third_party/quiche/src/quic/core/congestion_control/bbr_sender.cc of BBR https://datatracker.ietf.org/doc/html/draft-cardwell-iccrg-bbr-congestion-control.
