The issue covers everything we want to do around Congestion Estimation and Pion. This covers a Bandwidth Estimator in Pion, and generating feedback for remote peers.

@mengelbart is the owner of this work. If you have feedback/suggestions/ideas he knows this all the best!

• bc30165 Implement Sender/Receiver Reports
• c8a26a2 Implement Transport Wide Congestion Control Feedback
• Design a interface/API that all Bandwidth Estimators will satify
• Merge the NetworkConditoner so we can test our implementations
  • Start with basic tests (hard limits on total bandwidth/start queueing at certain bitrate]
  • Implement full test suite from RFC8867
• Implement Google Congestion Control
  • Have it be Sender estimates only using TWCC. No REMB our Receiver Reports.
• Implement FlexFEC
  • This will be needed by servers attempting to deliver Simulcast/SVC
• Make WebRTC Bandwidth Estimation accessiable to others
  • Write blog posts about what you are implementing/challenges
  • Write a dedicated chapter in WebRTC for the Curious about Bandwidth Estimation
• Make work accessible for other projects.

In the future we will also need

• Switch from Transport Wide Congestion Control to cc-feedback-message
  • This hasn't been adopted by anyone yet
• Investigate AdaptiveFEC
  • Paper

• Mozilla article on RMCAT
• Transport Wide Congestion Control
• Google Congestion Control
• RMCAT
• NADA
• GstConf Video on Transport Wide Congestion Control
• ion-sfu Transport Wide Congestion Control
