BBR Congestion Control Development

BBR is a new congestion control algorithm developed at Google.

There is a blog post on the launch of BBR for Google.com, YouTube, and Google Cloud Platform
There is a paper describing BBR in the February 2017 issue of CACM (the same content is in the ACM Queue BBR article from Oct 2016).
There are Internet Drafts specifying the BBR algorithm and the delivery rate estimation algorithm used by BBRv1.
BBR code from the BBR team at Google:
- BBRv1:
  - BBRv1 for Linux TCP (added in Linux v4.9: main commit)
  - BBRv1 for QUIC: .cc | .h
- BBRv2 (alpha):
  - BBRv2 alpha for Linux TCP
  - BBRv2 alpha for QUIC: .cc | .h
Quick start: a guide for getting started with the Linux TCP BBR implementation
