pub struct RoundTripEstimatorParams {
    ewma_cwnd_pct: Percentage<u32>,

Expand description

The round trip estimator parameters taken from consensus and used to estimate the round trip time on a circuit.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§ewma_cwnd_pct: Percentage<u32>

The “N” parameter in N-EWMA smoothing of RTT and/or bandwidth estimation, specified as a percentage of the number of SENDME acks in a congestion window.

A percentage over 100% indicates smoothing with more than one congestion window’s worth of SENDMEs.

§ewma_max: u32

The maximum value of the “N” parameter in N-EWMA smoothing of RTT and/or bandwidth estimation.

§ewma_ss_max: u32

The maximum value of the “N” parameter in N-EWMA smoothing of RTT and/or bandwidth estimation but in Slow Start.

§rtt_reset_pct: Percentage<u32>

Describes a percentile average between min and current ewma, for use to reset RTT_min, when the congestion window hits cwnd_min.
