Whether to implement a congestion control algorithm such as BBR CUBIC #20

Please explain what exactly your question is or what you want from me. My time is valuable to me, i don't like to base my answer on guessing what the question would be....

@prtd Hello，in kwik, I see "QUIC's congestion control is based on TCP NewReno [RFC6582]" ,so the congestion algorithm of Kwik uses NewReno。Is there a plan to support BBR or Cubic ?

Hi,

No plans yet. I would like to add some other congestion control algorithm, but congestion control is hard to implement / test, so would / will take a lot of time and there are dozens of other things in Kwik to improve, that should come first.

Why are asking? Do you have a use case that requires it?

Hi,@ptrd
I saw other quic projects implement multiple algorithms and asked by the way. At the same time, I also want to know which algorithm is better, or can choose and test it in practice. Is it convenient to disclose the plans of kwik in the future?

Hi,

There is no real planning. This is my hobby project, so i work on it when i have time and pick up something that i like doing or that i think needs improvement or like to experiment with.

Currently, i'm working on:

Things that are on my list:

As you see, this is a long list, I guess other CC algo's will not quickly get priority, especially because i have no compelling reason to implement it. For the things mention above, I have. For example, my first goal is to conform to the RFC's, and to do so stream priorities and connection migration must be implemented. W.r.t. CC, Kwik is conforming to the specification and I have no indications that it would not be working well.
