perf(qlog): introduce outer `Option`

6

Currently qlog is defined as: ```rust pub struct Qlog { inner: Rc, } ``` https://github.com/mozilla/neqo/issues/1894 documents our finding, that dereferencing the `Rc` is costly, i.e. showing up in our CPU...

feat(transport/cc): lower CWND reduction on ECN CE vs loss

5

Work in progress. Fixes https://github.com/mozilla/neqo/issues/3111.

transport: consider lower pacing rate in congestion avoidance

2

Neqo currently paces over half the RTT, i.e. 2x the current rate: https://github.com/mozilla/neqo/blob/207d309e941d3ae9384c191c13463dc81fca4ce9/neqo-transport/src/pace.rs#L19-L27 This is independent of the congestion control phase, i.e. same in slow start and congestion avoidance. In...

Lower CWND reduction on ECN CE vs loss

3

Today our Cubic implementation reacts to ECN CE the same way it reacts to inferred packet loss. `on_packets_loss` calls `on_congestion_event` the same way that `on_ecn_ce_received`. https://github.com/mozilla/neqo/blob/6d56ec96fc97b488b0d67df1e72807386fdb23dd/neqo-transport/src/cc/classic_cc.rs#L270-L326 https://github.com/mozilla/neqo/blob/6d56ec96fc97b488b0d67df1e72807386fdb23dd/neqo-transport/src/cc/classic_cc.rs#L328-L334 [RFC 8511](https://www.rfc-editor.org/rfc/rfc8511.html) suggests...

cc/cubic: consider >2 MSS increase on ACK

4

Currently `on_packets_acked`, we at most increase by 2 MSS per ACK: https://github.com/mozilla/neqo/blob/207d309e941d3ae9384c191c13463dc81fca4ce9/neqo-transport/src/cc/classic_cc.rs#L243-L257 I am not sure this artificial limit is needed, especially since outgoing packets will be paced. This code...

Should Neqo support the HTTP DATAGRAM Capsule?

4

> [3.5. ](https://www.rfc-editor.org/rfc/rfc9297.html#section-3.5)[The DATAGRAM Capsule](https://www.rfc-editor.org/rfc/rfc9297.html#name-the-datagram-capsule) > > This document defines the DATAGRAM (0x00) Capsule Type.

Today Neqo does not yet implement the ORIGIN extension, e.g. does not yet implement the HTTP/3 ORIGIN frame: https://github.com/mozilla/neqo/blob/0dc00b457f46659500ccba392b9b7bb06ef28826/neqo-http3/src/frames/hframe.rs#L18-L26 This is specified in RFC 9412: https://datatracker.ietf.org/doc/html/rfc9412 Firefox does support the...
