BBR Internet Draft
---
* There is an Internet Draft specifying BBR:
* BBR is a Congestion Control Working Group (CCWG) "working group item"
* Target: publish an experimental RFC documenting the algorithm
* IETF working group members are collaborating on github
* [https://github.com/ietf-wg-ccwg/draft-ietf-ccwg-bbr](https://github.com/ietf-wg-ccwg/draft-ietf-ccwg-bbr)
* Ideas or suggestions? Feel free to file a github issue.
* Specific editorial suggestions? Feel free to propose a pull request.
