General Fields

TLS Fields

username

Required, username used for ShadowQUIC authentication.

password

Required, password used for ShadowQUIC authentication.

sni

Optional, SNI used by the ShadowQUIC TLS handshake.

alpn

Optional, application-layer protocol negotiation list. Defaults to h3.

quic-versions

Optional, sets the supported QUIC versions. Available values: v1/v2. Default is v1.

udp-over-stream

Optional, sets whether to transmit UDP over stream. Default is false.

zero-rtt

Optional, sets whether to enable QUIC 0-RTT (Zero Round Trip Time) handshake.

keep-alive-interval

Optional, the interval time for sending keep-alive heartbeat packets to maintain connection activity, in milliseconds.

congestion-controller

Optional, sets the congestion control algorithm. Available values: cubic/new_reno/bbr. Default is cubic.

up

Optional, sets the client upload speed and enables Brutal negotiation through a mihomo private extension. Falls back to congestion-controller when unsupported.

down

Optional, sets the requested client download speed, capped by the Listener’s up, and enables Brutal negotiation through a mihomo private extension. Falls back to congestion-controller when unsupported.

cwnd

Optional, sets the initial congestion window size. Default is 32.

bbr-profile

Optional, sets the aggressiveness profile for the BBR algorithm. Available values: standard/conservative/aggressive. Only effective when congestion-controller is set to bbr.

max-datagram-frame-size

Optional, sets the maximum allowed datagram frame size, in bytes. Default is 1400.

max-open-streams

Optional, sets the maximum number of concurrent streams that can be opened simultaneously. Default is 1024.

recv-window-conn

Optional, sets the receive window size for an individual stream. If set to 0, the internal default value will be used.

recv-window

Optional, sets the connection-level receive window size. If set to 0, the internal default value will be used.

disable-mtu-discovery

Optional, sets whether to disable Path MTU Discovery. If set to true, a fixed MTU size will be used.
