Question: Can plugins modify the congestion control behavior?

[hawkinsw]

I am sorry to ask a meta question here, but I was just wonder whether or not you are considering plugins that have the capability to modify the congestion control algorithms in quic? There are protocols that do this type of thing (UDT3, https://en.wikipedia.org/wiki/UDP-based_Data_Transfer_Protocol) and I thought it might be really cool to have quic be able to do something similar.

I think that the work on making quick "pluginizable" is awesome and incredibly valuable. Thank you for working so hard on it! I apologize if the question is stupid, naive, or off topic. Please tell me if it is!

Thanks again!

Those kind of questions are welcomed! You can replace the congestion controller using this protoop: https://github.com/p-quic/pquic/blob/master/picoquic/protoop.h#L302-L314. We currently have no public plugins replacing the CC but we did experiment with it and were able to implement a new CC.

I close this issue as no further assistance seems required.
