Struct TransportConfig 

pub struct TransportConfig {
    pub congestion: Congestion,
    pub datagram_send_buffer: usize,
    pub datagram_receive_buffer: usize,
    pub max_idle: Duration,
    pub keep_alive: Duration,
    pub initial_mtu: u16,
}

Fields

congestion: Congestion

datagram_send_buffer: usize

Bytes quinn may hold in its outgoing datagram buffer.

This is a ceiling, not the latency bound: the engine’s admission control measures what is queued here against the QoS profile’s backlog threshold (Session::send_buffer_queued) and drops delta frames long before the buffer fills. What the size must guarantee is that a keyframe always fits — keyframes are never dropped, and a keyframe chunk that finds no room is retried with 1 ms sleeps and then abandoned, tearing the frame. So: the largest backlog a profile tolerates (3 frames at 6 Mbps / 30 fps is 75 KB) plus the largest keyframe with parity (a 2 s GOP at 6 Mbps can reach ~170 KB), with headroom.

initial_mtu: u16

Starting MTU assumption; DPLPMTUD probes upward from here.
