feat(bbr3) Implemented bbr3's latest version based on the RFC by Tipuch · Pull Request #2481 · quinn-rs/quinn

Tipuch · 2025-12-21T05:21:19Z

solves #1254
Based on https://www.ietf.org/archive/id/draft-ietf-ccwg-bbr-04.txt

tested with sudo tc qdisc add dev lo root netem delay 50ms 10ms distribution normal with a big file, this is a single connection
and it's BBR3 vs Cubic (the default) for quinn

1206KiB/s for BB3 vs 1049 KiB/s for Cubic so approximately 13% faster transfer speed (this is with a big file so over a long period of time).

Let me know if you need any additional information or if you want me to change the implementation in some ways.

Thanks for working on this! I'm excited to have this feature, and those performance numbers look promising. It's hard to read the vertical scales, but I guess the second chart is the new path? The pacing rate units don't look quite right.

What conditions was this tested in? It'd be interesting to contrast e.g. loopback, LANs, wifi, cellular, long fat networks, satellite networks, etc. We don't need all of that to merge this, but it would help inform what our guidance to users on its use should be, and might motivate future changes in default configuration.

Is there a strong reason for us to keep the old BBR code around? It hasn't received any attention in years, so unless it serves a very strong purpose I think it would be better for this change to replace it outright, perhaps by just deleting it in a final commit.

As this is a large body of algorithmically nuanced code, review will be difficult. To start with, can you reorganize the PR as a series of incremental, linear commits? For example, please remove merge commits and squash together WIP, incomplete, or later-revised changes, and separate changes to existing Quinn interfaces from the introduction of new logic.

Tipuch · 2025-12-25T06:22:19Z

This was tested on local with simulated network latency (between a client and a server from the examples provided in quinn) 100 ms ping with 20 ms jitter.
The top one is Cubic and the bottom one is BBR3, as for the units I used the same units as the previous implementation of BBR but I guess I'll change that for Bytes/sec instead. I'll reorder and polish the commit history as well.
I'll try testing it in different conditions and post the graphs here as well.
As for the previous version of BBR I think we can replace it as it doesn't seem to me like it was ever in working condition (because some of the output parameters weren't being applied to the connection).

I'll edit the history here soon, change the units for pacing rate and post more graphs under different condition :)

Tipuch · 2025-12-25T13:04:50Z

Alright I have cleaned up the history of commits and adjusted the units for pacing_rate

I'll get to doing some more tests under different circumstances now.

Tipuch · 2025-12-28T03:50:26Z

I'm not sure what's the best way to share the graphs with you, I tried to get an average sample and no outliers (positive or negative) for cubic vs bbr3:

Using the perf server and client with default settings and within lo without limits and using tc qdisc add dev lo root netem delay 50ms 10ms distribution normal

bbr3:

cubic:

Ralith

Thanks for putting this together! The commit organization is great.

Because this is marked as experimental and replaces obsolete and equally experimental code, I'm not inclined to block this on an in-depth review of the actual BBR logic, which would otherwise take us much longer. That said, some documentation around it would dramatically improve our ability to notice implementation errors, and make it much easier for yourself or others to update and debug it in the future. Appropriate documentation might heavily cite or even excerpt the IETF draft.

Tipuch · 2026-01-11T17:25:47Z

I just noticed there are some inconsistencies with what the value of the pacing gain when in the draining state in the ietf draft, I'll update its value soon with additional justifications

djc · 2026-01-11T21:31:07Z

Please rebase and squash all your commits on your next push.

Ralith · 2026-01-11T22:37:07Z

(don't literally squash them all, just assemble into a logical progression like before)

Tipuch · 2026-01-12T16:47:54Z

I introduced a bug within the latest changes, so I will first find it and fix it and then clean up the commits.

I introduced a bug within the latest changes, so I will first find it and fix it and then clean up the commits.

fixed the bug, there were a couple errors in calculations but the main issue was with how inflight was set, ack_eliciting is the number of packets, not an amount of bytes, resulting in underestimating inflight by a lot

Tipuch · 2026-01-13T14:30:40Z

Alright cleaned up the commits :)

happytrudy · 2026-01-31T12:02:06Z

When can this submission be merged? I need to use the BBR congestion control algorithm.

There is a newer version of the draft which changes some things, would it be alright to update this PR to the latest version in a new commit? @Ralith

There are some QUIC specific additions, among other small differences: https://www.ietf.org/archive/id/draft-ietf-ccwg-bbr-05.html#name-quic-offload-budget

Ralith · 2026-04-06T17:21:19Z

would it be alright to update this PR to the latest version in a new commit?

Staying up to date is ideal! Since I haven't been focusing on the mechanics of BBR itself, I don't think there's much drawback to squashing the update into the main commit here, so I don't feel strongly either way.

Tipuch · 2026-04-19T03:11:13Z

I updated to the newer draft @Fhokud I have fixed a couple of bugs in the implementation as well, could you take a look and see if you get better performance? Whenever is convenient for you. I'll work on adding tests to the main implementation as well

1 Gbps server to 1 Gbps client (via congested public networks)
Measures only the data volume transmitted via QUIC, and 210~ms latency,and severe packet loss
Average of 7 rounds of data

I've switched both the client and the server to a new ISP, so I can no longer reproduce the previous environment.

Thank you very much for the detailed graphs, how does loss % look like in those runs?

Was this test done with a single channel or with multiple channels?

Fhokud · 2026-04-23T02:01:48Z

Was this test done with a single channel or with multiple channels?

Multiple bidirectional streams over a single QUIC connection, initiated by the client with data subsequently written by the server.

Thank you very much for the detailed graphs, how does loss % look like in those runs?

I added some iperf3 UDP test with a packet size of 1200 b.
