max-outgoing-packet-size

Sets the maximum packet size Radiator constructs for a backend server.

server "PRIMARY" {
    max-outgoing-packet-size 16384;
    connect { protocol tls; host "primary.example.com"; port 2083; }
}

The default is 4096 bytes. Valid values are 20 through 65535. UDP permits values up to 4096. Larger values require outbound TCP or TLS.

Radiator fails a request that exceeds this value. Radiator does not truncate or split the packet. The operating system may fragment a UDP datagram at the IP layer.

When a larger upstream hop follows a smaller downstream hop, Radiator adds the RFC 7930 Response-Length attribute to the request.
