Expand description

Per-connection congestion state.

Fields§

§id: CccConnId

Unique connection identifier.

§cwnd: u64

Current congestion window (bytes).

§ssthresh: u64

Slow-start threshold (bytes).

§state: CccState

Current FSM state.

§rtt_ms: f64

Smoothed RTT (ms), exponential weighted moving average.

§rtt_var: f64

RTT variance (ms).

§in_flight: u64

Bytes currently in flight.

§bytes_acked: u64

Total bytes acknowledged.

§bytes_lost: u64

Total bytes lost.

§last_ts: u64

Timestamp of the last event (monotonic ms counter, internal).

Implementations§

Source §

impl CccConnection

Source

pub fn apply_cwnd_jitter(&mut self, min_cwnd: u64, max_cwnd: u64)

Apply a small random jitter (±1 %) to the congestion window.

Used by algorithms that need to break synchronisation among multiple flows. The magnitude is bounded so cwnd never leaves [min, max].
